1.1BACKGROUND OF THE STUDY
Biometric Verification is as old as computer vision, both because of the practical importance of the topic and theoretical interest from cognitive scientists. Despite the fact that other methods of identification (such as fingerprints, or iris scans) can be more accurate, face recognition has always remains a major focus of research because of its noninvasive nature and because it is people's primary method of personal identification. Face recognition technology is gradually evolving to a universal biometric solution since it requires virtually zero effort from the user end while compared with other biometric options like fingerprints, and iris scan.
Biometric face recognition is basically used in three main domains: class attendance systems and employee management, visitor management systems and last but not the least authorization systems and access control systems.
Traditionally, student’s attendances are taken manually by using attendance sheet given by the faculty members in class, which is a time consuming event. Moreover, it is very difficult to verify one by one student in a large classroom environment with distributed branches whether the authenticated students are actually responding or not.
This research work show how face recognition can be used for an effective attendance system to automatically record the presence of an enrolled individual within the respective venue. Proposed system also maintains a log file to keep records of the entry of every individual with respect to a universal system time.
The manual student attendance system is not efficient and accurate, it is easy to manipulate and be duplicated. The reasons why we embark on the research are:
1. To make attendance system more efficient and accurate.
2. To know the number of students attended lecture using the biometrics
3. To capture student biometric data
1.3 PURPOSE OF STUDY
The purpose of this study work is as follows:
i. To design and construct biometric based attendance system (facial recognition).
ii. To ease student attendance in schools.
iii. To eliminate multiple attendance during lecture periods.
Research methodology is a careful study or investigation, especially in order to discover new knowledge or information. The method used to collect data, process the data and interpret the data or information. Hence research methodology should be sound enough to make attainment of the set objectives possible. One of the important issues in building software is deciding what programming language to be used. Visual Basic .NET has been chosen to design the interface (front end). Microsoft Access will be used to design the database (back end) which will be used to store data of student.
Pc camera (Web cam) use as the hardware component that will capture the image of student which will be passing to the application to add to the attendance of the student in the database.
1.5 THE SCOPE OF PROJECT
The scope of this project is to develop a computerized biometric based attendance application/system using facial recognition, specially designed to meet the needs of Kaduna Polytechnic by using the recognition technique(s) that will be implemented.
1.6 EXPECTED CONTRIBUTION TO KNOWLEDGE
The biometric based attendance system (facial recognition) will enlighten student on how to use an automated attendance system in marking students attendance in a classroom and will also help the lecturer to keep tract of truant and punctual students to lectures.
1.7 DEFINITION OF TERMS
· Biometric: is refer to the process by which a person’s unique physical and other traits are detected and recorded by an electronic device and system as a means of confirming identity.
· Facial recognition (face recognition): is the ability of a computer to scan, and recognize human faces for use in identifying people.
· Access control: is a way of limiting access to a system or to physical or virtual resources.
- Interface: a point where two systems, subjects, organizations, etc. meet and interact. It is referring to a device or program enabling a user to communicate with a computer.
