Objective

To implement a system that track attendance using: Database system:

Track of all information

Fingerprints: Identity Recognition

Automatically generates absent warning

5

Background

Biometrics

What Biometric is?Types of Biometrics: Properties

Fingerprints Fingerprints are unique for each finger of a person

Face Recognition non-intrusive, hands-free, continuous and accepted by most users

Speaker Recognition Easy to implement

Iris Recognition It does not require physical contact with a scanner, Expensive.

Hand and Finger Geometry These methods of personal authentication are well established.

Signature Verification Uses the dynamic analysis of a signature to authenticate a person.

Fingerprint Sensors

Fingerprint sensors how its work? price

Optical Capture a digital image of the fingerprint. 50 -100 $

Ultrasonic Use very high frequency sound waves to enter the epidermal layer of skin.

500-1000 $

Capacitance Use the principles associated with capacitance in order to form fingerprint images.

100-150 $

Thermal Sensors Use the same pyro-electric material that is used in infrared cameras.

200 $

RF Sensors Low radio frequency (RF) signal is applied to the user’s finger. 200 $

Database

Files Vs. DBMS Files Complex Code for Queries Security of Data

RDBMS

9

Application Server

Using PHP under LAMP (GNU/Linux , Apache , MySQL, PHP)

CodeIgniter:- Open source PHP web application framework Small footprint MVC structured code (Model-View-Controller) Internal security features (XSS Filtering,

Encryption classes, input validation classes)

System Requirements

Non-Functional Requirements Cost-effective

Open source Usability

11

System Requirements

Functional Requirements Instructor enable the terminal (tracking) Students register attendance (fingerprint) Record absentees Send notification email to them Generate warnings automatically Instructor detailed reports of attendance in his

classes (web interface)

System Architecture

Decentralized Vs. Centralized. Factors

- Fingerprints Capacity

- Labor work

- Flexibility Centralized Wins !!

Application Server All responses are encoded in JSON

(JavaScript Object Notation) Binary Data are Base64 encoded

Provide a pre-defined tasks to the fingerprint terminal Authorize instructors Provide a list of students along with their

fingerprints in the current class using instructor id & current date and time

Add absent students to the database. Limit what users can do with the database.

20

Fingerprint Terminal Emulator Written in Java Object Oriented Programming paradigm Using Eclipse as an integrated development

environment Futronic Fingerprint Software Development Kit

for fingerprint matching “json_simple” for JSON encoding & decoding Communicate with the Application server using

HTTP protocol Emulate both the numbered keyboard and the

LCD screen Communicate with the fingerprint sensor using

Futronic Fingerprint SDK

21

Web Interface Levels of Access

One level Instructor

Functions: Detailed Report of Students’ Attendance in a

Section View, edit absence records Email Approve Warnings

Security Avoid Security By Obscurity Allow only authorized users to gain access Restrictive regarding which characters to

allow in URL strings Filter the data as if it were tainted Validate the data to ensure it confirms the

correct type, length and size Escape the data before submitting it into the

database All cookies are encrypted
