Objective To implement a system that track

attendance using: Database system:

Track of all information

Fingerprints: Identity Recognition

Automatically generates absent warning

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 SensorsFingerprint 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)

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

Conclusion Standards

Fingerprint Terminal Emulator Java Standard Edition 6 (1.6)

Web Interface XHTML 1.0 (A Reformulation of HTML 4 in XML 1.0) Cascading Style Sheets 2.1 (CSS 2.1) ECMAScript (aka. JavaScript)  ECMA-262

specification and ISO/IEC 16262 Communication

Hypertext Transfer Protocol -- HTTP/1.1 (RFC 2616) JSON (JavaScript Object Notation) (RFC 4627)

26

Conclusion Why SQU should adapt this solution?

Environment (paperless) Lower total-cost of ownership Time-effective Easy and fast access to data Less human error (more affective tracking

system)
