ONLINE CRIME REPORTING

1.3 Project purpose

Usually the citizen has to go to police station to make a complaint. Here we have given an

opportunity to make a complaint through online and the actors will be taken by the police

officers immediately. The communication for officers will be easy. The license can be get easily

through online if it is selected by the officers via sms and mail.

The main purpose behind the Online crime reporting system was to improve the

effectiveness of policy performance; to improve the efficiency of police procedures; for

example, by eliminating redundant processes in the registration of criminal cases; and to

improve the quality of management information provided for senior policy decision-making,

particularly through integration of previously separate information systems.

Within the focus on effectiveness, there was a concern about the non-transparent, even

dishonest nature of police work, which had become synonymous with corruption and delay. The

intention was that the new system - through its automation of previously human processes and

through its state-wide and online accessibility - would make the registration, processing and

follow-up of criminal cases more open. Under the existing regime, many police require a bribe

before they are willing to register a case, and also require a bribe to be paid before they answer

any query about the case, such as its progress, or other information held on file.

It was partly this poor image of police functioning, that led the Chief Minister of the

State to impose the system on the police service. There were also drivers from the failure of

police to properly prosecute some high-profile criminal cases that had political overtones;

something which was politically-damaging and seen as requiring an equally high-profile

reaction.

1.4 Objectives

Generally many crimes seen by the public will not reach to the police due to many reasons like

fear, Lack of time, Ignorance. Due to this reason many cases are not even reaching the police

station. Though some cases are registered they are not investigated properly due to lack of

evidences and Cooperation of the public. This software helps the public to report about the

crimes to the police without any fear in correct time. This is helpful to police in solving the

cases .This is also helpful for higher authorities of police to have an overview about the progress

of the investigation.

ECOPS is an online reporting service to which the internet user can report crimes

committed on or through the Internet. The impact of IT and communications is traversing at afast pace. As information for the department is crucial, an enterprise IT tool for enhancing the

performance of the police officials became necessary called ONLINE CRIME REPORTING or

E-Computerized Operations for Police Services, the main purpose is to maintain information,

monitor and enhance the performance of the department.

The focus of ONLINE CRIME REPORTING is to computerize the activities of

controlling crime, administration and support services across the state in an integrated fashion

so as to enable the division heads and senior officers to obtain the relevant information. Besides,

it is also envisaged to reduce dependence on paper and help in automatic maintenance of

registers and generation of reports, data analysis, better planning and coordination, speedy

detection of crimes and monitoring the prosecutions.

2. SYSTEM ANALYSIS

2.1 Existing system

The normal public in India is afraid to give a complaint in police station because they

are filled with a false fear about the police department. An online complaint registration system

will solve the fear of the public and will also help to police dept in catching criminals. It will

improve the service, so you dont have to wait on hold on the telephone or go down to the

station to file a report.

2.2 Drawbacks of existing system

Existing system is time consuming

Corrections & maintenance should be done manually

It needs more man power

There may be mistakes while maintaining data manually.

2.3 Proposed system

An online solution is very useful as the solution is inherently distributive. This distributive

characteristic of the online solution helps in getting the different police stations to share

information & get in contact with one another.

The reports filled online are checked at the administrative department to use if any

information is lacking or to check the status of the report.

Administrator:

This module is accessible to some VIPs like SP, DCP, and DIG etc. By using

this module they can give any caution to the police department. Also they can perform

updations to the crime report database.

3. REQUIREMENT SPECIFICATION

3.1 Requirement study and analysis

Generally many crimes seen by the public will not reach to the police due to many reasons like

fear, Lack of time, Ignorance. Due to this reason many cases are not even reaching the police

station. Though some cases are registered they are not investigated properly due to lack of

evidences and Cooperation of the public. This software helps the public to report about the

crimes to the police without any fear in correct time. This is helpful to police in solving the

cases .This is also helpful for higher authorities of police to have an overview about the progress

of the investigation. An online solution is very useful as the solution is inherently distributive.

This distributive characteristic of the online solution helps in getting the different police stations

to share information and get in contact with one another.

With ECOPS, the exchange of information within police stations and other senior police

officers in the departments is faster. It also streamlines the workflow in police department

machinery. A central database permits the police units to operate more efficiently leading to

speedy detection of crime and prosecution monitoring. The senior police officers of the state can

access the reports, which allow them to take quick and timely decisions. Crime analysis reports

will enable the senior police officers to observe the crime trends and to guide the investigating

officers. The technological benefits of ECOPS are to maintain information, monitor and

enhance the performance of the department, to take a critical look at the existing system,

processes and procedures of the department so as to identify and remove the redundancy.

ECOPS is envisaged to reduce the fair amount of paper work and helps in the automatic

maintenance of registers and generation of reports, data analysis, better planning and

coordination, timely decision and speedy detection of crime and prosecution monitoring. All

these factors have contributed to a higher moral of the police officials at all the levels in police

department. The case registered at one police station can be tracked at any police station.

This reduces the discretionary dependence of police. Once the case is registered the

investigation and follow up activities relating to the case cannot be delayed. The grievances

handling is more efficient. Now, the citizens will have access to senior officers through the web.

ECOPS introduced transparency and accountability in the whole system.

The User Interface should be user friendly to the user who uses the home page by whichhe/she can easily register.

The Operations should take place transparently.

User:

User can send the complaints to police and they can view the complaint report. User can

perform these tasks only when he logins to his account otherwise he has to register his new

account. Police send the status report to the users based on their investigation. The user can

check the status of their complaints with the help of complaint id given. The user can register

his complaints to the police and view the thieves information.

Administrator:

Higher authorities like VIPS, CP, and DCP can view the complaints which are sent by

the public. The administrator has to login with their account in order to perform his actions.

They can send alert messages to the police department regarding any future complications. The

administrator can also send cautions to the users. Unlike police who can view complaints

specific to his area the administrator can view the complaints universally.

Police Department:

Basing on the complaints given by the public, police can view them and take appropriate

action timely. The police has to login with their account to view the complaints and to send the

status of the complaints to the users. They can update the status of the complaint basing on the

progress of investigation. They will also receive alerts from the higher authorities regarding

warnings and can take action in advance.

4.3 Feasibility Analysis

Feasibility studies aim to objectively and rationally uncover the strengths and weaknesses of the

existing business or proposed venture, opportunities and threats as presented by the

environment, the resources required to carry through, and ultimately the prospects for success.

In its simplest terms, the two criteria to judge feasibility are cost required and value to be

attained. As such, a well-designed feasibility study should provide a historical background of

the business or project, description of the product or service, accounting statements, details of

the operations and management, marketing research and policies, financial data, legal

requirements and tax obligations. Generally, feasibility studies precede technical developmentand project implementation.

5. DATA FLOW DIAGRAMS

5.1 Rules of data flow diagram

Data flow diagram is a pictorial representation of the system in which flow of data from one

process to another process is described. A Data Flow is composed of

Data movement shown by arrows.

Transformation or process of data shown by named circle or rounded rectangle.

Sources and destination of data represented by named rectangles.

Static storage or data at rest denoted by an open rectangle that is named.

Data Flow Diagrams are of two types:

Physical Data Flow Diagrams:

These are implementation-dependent i.e., they show the actual devices, departments, people,

etc., involved in the system.

Logical Data Flow Diagrams:

These diagrams describe the system independently of how it is actually implemented, they show

what takes places, rather than how an activity is accomplished.

The DFD is intended to represent information Flow but it is not a flow chart and is not

intended decision-making, flow of control, loops and other procedural aspects of the system.

DFD is a useful Graphical tool and is applied at the earlier stages of requirements analysis. It

may be further refined at preliminary design stage and is used as mechanism for top-level

structural design for software.

The DFD drawn first at a preliminary level is further expanded into greater details:

The context diagram is decomposed and represented with multiple rectangles.

Each of these rectangles may be decomposed further and given as more detailed DFD.

Explanation of DFD.

Context diagram:

Its a diagram, which shows whole system at once. The sources in context diagram for

this system are USER, ADMINISTRATOR, POLICE and these are linked to the

ONLNECRIMEREPORTING. The Context Diagram is shown in fig (6.1.1):

5.2 Levels of data diagram

Level -1 Diagram:

User login process is the Level-1 DFD shown in Fig(6.2.1). Here user has to enter into the

registering complaint area any one register the complaint so there is user id and password for it.

After entering the complaint and pressing submit it will be send to the complaintdatabase. If his complaint has been successfully entered in to the database he is allotted with a

self generated no which is used for the further purposes.

The user can view the status of his compliant in the status menu by entering the self

generated no given by the system.


8/2/2019 ecop doc

The user can also view the details of the thieves present in the various locations to make

him cautious .By just selecting the location and the thieves id he can view the details of the

thieves with his photo and reward announced on him by the police.

Fig.5.2.1 : Level-1 Diagram

Level -2 Diagram:

Police login is Level-2 DFD as shown in Fig(6.2.2). In this level, different police officers of

different locations were provided with their particular user id and password using which they

have to login in. The entered user id and password were validated and if correct they were made

to login. Here they can view the alert message given by the administrator and also the caution


8/2/2019 ecop doc

by the administrator to the particular complaint. Police officers can see the complaints

belonging to their locality only.

Level -3 DIAGRAM:

Level-3 DFD diagram is for administrator .Here he consists of login page .Where he has to login

using user id and password provided to him. After entering user id and password they are

validated and if correct they made to enter into the page. Here he has two tasks they are sending

alert messages and caution for the particular complaint to the police. In the caution first he has

to select the location and then the complaint id and then he has to send the status and caution to

the particular complaint. The entered alert, status, and caution were sent to the respective

databases.

5.3 Flow chart

A flowchart is a type of diagram that represents an algorithm or process, showing the steps as

boxes of various kinds, and their order by connecting these with arrows. This diagrammatic

representation can give a step-by-step solution to a given problem. Process operations are

represented in these boxes, and arrows connecting them represent flow of control. Data flows

are not typically represented in a flowchart, in contrast with data flow diagrams; rather, they are


8/2/2019 ecop doc

implied by the sequencing of operations. Flowcharts are used in analyzing, designing,

documenting or managing a process or program in various fields.

8. IMPLEMENTATION AND TESTING

8.1 Implementation

About java

Now-a-days all are familiar with Internet, the worldwide network of computers, which connects

together thousands of computer all over the world. These network connections are increasing

day by day in a rapid rate, so the network traffic is increasing at a pulse rate. Computers

connected to the net are from many different manufacturers, running on different operating

systems and they differ in architecture, computing power and capacity. By considering this

point SUN Microsystems Corporation felt the need for a new programming language suitable

for this heterogeneous Environment and java was the solution. This breaks barriers between

different computers, chips and operating systems. Using java your application become

compatible with all operating systems.

Features of java:-

Simple

Secure

Portable

Object oriented

Robust

Multithreaded

Simple


8/2/2019 ecop doc

47/71

47


It is simple for professional programmer to learn & they can use it effectively. If we

already know object oriented programming, then learning java is very easy. It inherits syntax

from c & object oriented features from c++, so if the user knows c\c++ then it will be a easy

way to do effective java programming.

Secure

As we know many people are effected by viral infection when they download an

executable file or program. Rather than, virus programs we have malicious programs that can

gather private information, such as credit card number, bank account balances & passwords by

searching the contents of your computers local file system. Java has a better answer for this

effect i.e., FIREWALL between networked application and your computer.

Portable

As already we have discussed about compatibility of operating system, computers,

chips. In Internet the programs have to be dynamically downloaded to all the various types of

platforms. For this purpose java program will generate a byte code (which is not a executable

code). Byte code is a highly optimized set of instructions designed to be executed by java run

system, which is called as JVM (Java Virtual Machine).

Object-Oriented:-

Java is purely object oriented. The object model in java is simple and easy to extend,

while simple types, such as integers, are kept as high-performance non-objects.

Robust

The ability to create robust programs was given a high priority in the design of java. To

gain reliability, java restricts you in a few key areas, to force you to find your mistakes early in

program development. At the same time, java frees you from having to worry about many of the

most common causes of programming errors. Because java is a strictly typed language, it

checks your code at Compile time. Java is robust for two reasons; they are Memory

management& mishandled exceptional task in traditional programming environments.

What is JDBC?

JDBC is a Java API for executing SQL statements. (JDBC is often thought of as Java

Database Connectivity) .It consists of a set of classes and interfaces written in the java

programming language.

Using JDBC, it is easy to send SQL statements to virtually any relational database. In

the other words, with the JDBC API, it is not necessary to write to one program to access a

Sybase database, another program to access Informix database, another program to access

Oracle database, and so on. One can write a single program using the JDBC API, and the

program will be able to send SQL statements to the appropriate database. The combinations of

JAVA and JDBC lets a programmer writes it once and run it anywhere.

Java, being robust, secure, easy to use, easy to understand, and automatically

downloadable on a network, is an excellent language basis for database applications.

JDBC extends what can be done in Java. For example, with Java and the JDBC API, it is

possible to publish a web page, which contains an applet that uses information obtained from a

remote database. With more and more Programmers using the Java Programming language, the

need for easy database access from java is continuing to grow.

MIS managers like the combination of Java and JDBC because it makes disseminating

information easy and economical, Businesses can continue to use their installed database and

access information even if it is stored on different database management systems. Development

time for new application is short. A programmer can write an application or an update once, putit on the server, and everybody has access to the latest version. A Low Level API and a Base for

Higher-level APIs.


8/2/2019 ecop doc

49/71

49


JDBC is a Low level interface that means that it is used to invoke SQL commands

directly, it works very well in this capacity and is easier to use than other database connectivity

APIs, but it was designed to be a base upon which to build higher level interfaces and tools.

A high level interface is user-friendly, using a more understandable or more

convenient API that is translated behind the scenes into a low level interface such as JDBC. At

the time of writing, two kinds of higher level APIs are under development of top of JDBC.

1) An embedded SQL for Java. At least one vendor plan to build this DBMS implement SQL, a

language designed specifically for use with databases. JDBC requires that the SQL statements

be passed as Strings to Java methods. The embedded SQL preprocessor then translates this

JAVA/SQL mix into Java with JDBC calls.

2) A direct mapping of relational database tables to Java classes. In this object/relational

mapping, each row of the table becomes an instance of that class, and each column value

corresponds to an attribute of that instance. Programmers can then operate.

ODBC is hard to learn. It mixes simple and advanced features together, and it has

complex options even for simple queries. JDBC, on the other hand, was designed to keep simplethings simple while allowing more advanced capabilities where required.

A Java API like JDBC is needed in order to enable a Pure Java solution. When ODBC

is used, the ODBC Driver Manager and drivers must be manually installed on every client

machine. When the JDBC driver is written completely in Java, however, JDBC code is

automatically installable, portable, and secure on all platforms from network computers to

mainframes.

Java server page (jsp)

Java Server Pages (JSP) is a new technology for web application development that

has received a great deal of attention since it was first announced.

Why is JSP so exciting?

1. JSP is Java-based, and Java is well-suited for enterprise computing.

In fact, JSP is a key part of the Java 2 Enterprise Edition (J2EE) platform and can take

advantage of the many Java Enterprise libraries, such as JDBC, JNDI, and Enterprise Java

Beans.

2. JSP supports a powerful model for developing web applications that separates presentation

from processing.

In the early days of the Web, the only tool for developing dynamic web content was the

Common Gateway Interface (CGI). CGI outlined how a web server made user input available to

a program, as well as how the program provided the web server with dynamically generated

content to send back. CGI scripts were typically written in Perl. (In fact, CGI Perl scripts still

drive numerous dynamic web sites.) However, CGI is not an efficient solution. For every

request, the web server has to create a new operating-system process, load a Perl interpreter and

the Perl script, execute the script, and then dispose of the entire process when it's done.

To provide a more efficient solution, various alternatives to CGI have been added to

programmers' toolboxes over the last few years: FastCGI, for example, runs each CGI programin an external permanent process (or a pool of processes). In addition, mod_perl for Apache,

NSAPI for Netscape, and ISAPI for Microsoft's IIS all run server-side programs in the same

process as the web server itself. While these solutions offer better performance and scalability,

each one is supported by only a subset of the popular web servers.

The Java Servlet API, introduced in early 1997, provides a solution to the portability

issue. However, all these technologies suffer from a common problem: HTML code embedded

inside programs. If you've ever looked at the code for a servlet, you've probably seen endless

calls to out.println( )that contain scores of HTML tags.

For the individual developer working on a simple web site this approach may work fine,

but it makes it very difficult for people with different skills to work together to develop a web

application. This is becoming a significant problem. As web sites become increasingly complex

and are more and more critical to the success of an organization, the appearance and usability of

the web interface becomes paramount. New client technologies, such as client-side scripts and

DHTML, can develop more responsive and interactive user interfaces, style sheets can make it

easier to globally change fonts and colors, and images can make the interface more appealing.

At the same time, server-side code is getting more complex, and demands for reliability,

performance, and fault tolerance are increasing.

The growing complexity of web applications requires a development model that allows

people with different skills to cooperate efficiently.

Java Server Pages provides just such a development model, allowing web page authors

with skills in graphics, layout, and usability to work in tandem with programmers who are

experienced in server-side technologies such as multithreading, resource pooling, databases, and

caching. While there are other technologies, such as ASP, PHP and ColdFusion, that support

similar development models, none of them offers all the advantages of JSP.

Introduction to Database Management System (DBMS)

A Database is an integrated collection of user related data stored with minimum redundancy,

serves many users/applications quickly and efficiently.

A database system is basically a computerized record keeping system, i.e. it is a computerized

system whose overall purpose is to maintain information and make that information available on

demand. DBMS is a collection of inter-related data and set of programs that allow several users to

access and manipulate data. Its main purpose is to provide users with an abstract view of the data, i.e.

the system hides certain details of how the data is stored and maintained.

Database Management System is divided into 4 main components

Database

Hardware

Software

User

Database:

It consists of collection of persistent data that is used by the application system.

Hardware:

The processor(s) and associated main memory that are used to support the execution of database

system software..

Software:

The layer between the physical database and the users that handles all requests from the user for access

to the database.

User:

There are three types of users

Application Programmers

End User

Database Administrator (DBA)

Types of dbms

There are four major categories of DBMS data models.

Hierarchical

Network

Inverted

Relational

Relational database management systems

Database Management System has evolved from hierarchical to network to relational

models. Today, the most widely accepted database model is the relational model. The relational

database management system uses only its relational capabilities to manage the information

stored in the database. The relational model has three different aspects.

Structures

Operation

Integrity rules


8/2/2019 ecop doc

54/71

54


Structures:

They are well-defined objects that store the data of a database structure and the data contained within

them can be manipulated by operations.

Operations:

They are clearly defined actions that allow users to manipulate the data and structures of a

database. The operations on a database must adhere to a predefined set of integrity rules.

Integrity rules:

They are laws that govern which operations are allowed on the data and structures of a

database. Integrity rules protect the data and the structures of a database.

A DBMS can be regarded as relational only if it obeys a set of 12 rules formulated by

Dr.E.F.Codd These rules define the scope and functionality of a relational database.

There is a single overall rule called Zero Rule which is a foundation rule that covers

all other rules. It states that

Any truly relational database must be manageable entirely through its relational capabilities.

The twelve rules are as follows:

Rule 1: The information rules

Rule 2: The guaranteed access rule

Rule 3: The systematic treatment of null values

Rule 4: The database description rule

Rule 5: The comprehensive sub-language rule

Rule 6:The view update rule

Rule 7: The insert, update and delete rule

Rule 8: The physical data independence rule

Rule 9: The logical data independence rule.

Rule 10: The integrity independence rule.

Rule 11: The distribution independence rule.

Rule 12: The no subversion rules.

Why Oracle?

Even though the architecture of all RDBMS is same but the features are different from

different RDBMS. Oracle, Sybase, Informix. As per the features concerned all the RDBMS can

be related as it. But with the easiness, demand it is better to go for Oracle.

Because the professional availability in Oracle is high compared to other RDBMS

professionals. Because the availability is high the manpower cost will be less compared to

Sybase professionals, Informix professionals. Even the support from the vendors in also hig in

Oracle environment rather than other RDBMS.

Oracle9i is regarded as the RDBMS because it is the most widely acclaimed package

across the globe with its 100% client-server architecture. Oracle has in-built features like data

integrity, security, reverie and backup and total GUI based presentation and can easily and

efficiently support small to very large scale applications.

Database connections:

The database connection string is the only JDBC component that references the

particular database being accessed. You must provide a specific driver connection string that

uses the protocol defined for the driver. The JDBC Driver Manager class to determine which

driver to load uses the protocols currently maintained by Java Soft.

A Query returns a Result set object. This object contains the results of the query in a

form of that can be accessed by the application. If the query has no results, the Result Set object

contains no rows.

Otherwise it contains rows of data matching the query (up to the limit specified by the

database). If the database supports doing so, you can set the maximum number of rows using the

Statement class method setMaxRows ().

What is Testing?

A process of executing a program with the explicit intention of finding errors, that is making the

program fail.

Software Testing:

It is the process of testing the functionality and correctness of software by running it. Process of

executing a program with the intent of finding an error.

A good test case is one that has a high probability of finding an as yet undiscovered

error. A successful test is one that uncovers an as yet undiscovered error. Software Testing is

usually performed for one of two reasons:

Defect detection

Reliability estimation

Black Box Testing:

Applies to software systems or module, tests functionality in terms of inputs and outputs

at interfaces.Test reveals if the software function is fully operational with reference to

requirements specification.

White Box Testing:


8/2/2019 ecop doc

57/71

57


Knowing the internal workings i.e., to test if all internal operations are performed

according to program structures and data structures.

To test if all internal components have been adequately exercised.

Software Testing Strategies:

A strategy for software testing will begin in the following order:

Unit testing

Integration testing

Validation testing

System testing

Unit testing

It concentrates on each unit of the software as implemented in source code and is a white

box oriented. Using the component level design description as a guide, important control paths

are tested to uncover errors within the boundary of the module. In the unit testing,

The step can be conducted in parallel for multiple components.

Integration testing:

Here focus is on design and construction of the software architecture. Integration testing

is a systematic technique for constructing the program structure while at the same time

conducting tests to uncover errors associated with interfacing. The objective is to take unit

tested components and build a program structure that has been dictated by design.

Validation testing:

In this, requirements established as part of software requirements analysis are validated

against the software that has been constructed i.e., validation succeeds when software functions

in a manner that can reasonably expected by the customer.

System testing:


8/2/2019 ecop doc

58/71

58


In this software and other system elements are tested as a whole.

8.2 TESTING

8.2.1. TEST CASE REPORT

Having test cases that are good at revealing the presence of faults is central to successful

testing. The reason for this is that if there is a fault in a program, the program can still provide

the expected behavior for many inputs. Only for the set of inputs that exercise the fault in the

program will the output of the program deviate from the expected behavior. Hence, it is fair to

say that testing is as its test cases.

CONCLUSION


8/2/2019 ecop doc

69/71

The technological benefits of ECOPS are to maintain information, monitor and enhance

the performance of the department, to take a critical look at the existing system, processes and

procedures of the department so as to identify and remove the redundancy.

The case registered at one police station can be tracked at any police station. This

reduces the discretionary dependence of police. Once the case is registered the investigation and

follow up activities relating to the case cannot be delayed.

All these factors have contributed to a higher moral of the police officials at all the

levels in police department. This project result in great improvement in the organizations

functioning by reducing the effort spent by the general people.

GOALS:

Improve efficiency in police department

Availability of online police service to citizens

Availability of data to senior officials for quick decision making

Better administration and co-ordination

Speedy detection of crimes

Duplication of work avoided

Retrieval and access of data is easy

Paper work is drastically reduced

Automatic maintenance of registers

GLOSSARY

Project management is the discipline of planning, organizing, securing, and managing

resources to achieve specific goals. A project is a temporary endeavor with a defined beginning

and end (usually time-constrained, and often constrained by funding or deliverables),

undertaken to meet unique goals and objectives, typically to bring about beneficial change or

added value. The temporary nature of projects stands in contrast with business as usual (or

operations), which are repetitive, permanent, or semi-permanent functional activities to produce

products or services. In practice, the management of these two systems is often quite different,

and as such requires the development of distinct technical skills and management strategies.

The primary challenge of project management is to achieve all of the project goals and

objectives while honoring the preconceived constraints. Typical constraints are scope, time, and budget. The secondaryand more ambitiouschallenge is to optimize the allocation of

necessary inputs and integrate them to meet pre-defined objectives.
