Objective

To implement a system that track
attendance using:

Database system:


Fingerprints:


Track of all information
Identity Recognition
 Automatically generates absent warning
4
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.
6
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
8
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)


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
Centralized Wins !!
- Flexibility

Application Server

All responses are encoded in JSON
(JavaScript Object Notation)


Provide a pre-defined tasks to the fingerprint
terminal




Binary Data are Base64 encoded
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.

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

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

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)
