A Fingerprint Based Biometric Authentication and Identification System for Time and Attendance Management

...A FINGERPRINT BASED BIOMETRIC AUTHENTICATION AND IDENTIFICATION SYSTEM FOR TIME AND ATTENDANCE MANAGEMENT ABSTRACT This project is about designing a system that automates the whole process of taking attendance and maintaining its records in an academic institute. Managing people is a difficult task for most of the organizations, and maintaining the attendance record is an important factor in people management. When considering academic institutes, taking the attendance of students on daily basis and maintaining the records is a major task. Manually taking the attendance and maintaining it for a long time adds to the difficulty of this task as well as wastes a lot of time. For this reason an efficient system is designed. This system takes attendance electronically with the help of a fingerprint sensor and all the records are saved on a computer server. In order to mark the attendance, student/staff has to place his/her finger on the fingerprint sensor. On identification student’s attendance record is updated in the database and he/she is notified through a screen. .

Design and Implementation of a Bio-Metric (Fingerprint) Clocking System

...institution or organization can be very laborious using the conventional method of paper sheets and old file system method. Every corporate organization poses some standards concerning how attendance is to be confirmed for staff in offices. This is to enable the management of the organization identify those staff that are punctual and competent, that is why keeping the accurate record of attendance is very important. Also in institutions, tracking and monitoring staff time of attendance could pose a tedious task, time consuming and as well prone to errors. As an alternative to the traditional manual clocking process by staff in offices, biometrics characteristics can be used for authenticating staff. This research will focus on developing a Fingerprint based Biometric Clocking System.  The fingerprint Biometrics is adopted in this research work due to the fact that it is one of the most successful applications of biometric technology. In the manual signing processes, where a sheet of paper is placed at the entrance of the office for staff to write their names and signature as a form of confirming their presence for a particular day in the office, falsification in staff attendance mostly occur. A situation whereby a staff can sign on behalf of his or her colleague as being present in the office when that is not true. This can be so difficult to prevent from happening especially for large offices where row count can take longer time. The trending concern in this modern age is regarding...

Automated Attendance Monitoring System

... Excessive school absence is a precursor of school dropout and is related to juvenile delinquency. And, because average daily attendance rates are a common determiner of school funding, absences mean that schools have less resources to do the job. Given all this, it is not surprising that reducing school absences is a top priority for many schools. (http://smhp.psych.ucla.edu) Now-a-days intelligent automation has stepped its presence in every field all over the world. This project has a stepping in the attendance and power management of the classrooms in the colleges/schools.

Electronic Daily Time Record

...Development of Attendance Management System using Biometrics. O. Shoewu, Ph.D.1,2* and O.A. Idowu, B.Sc. 1 1 Department of Electronic and Computer Engineering, Lagos State University, Epe Campus, Nigeria. 2 Department of Electrical and Electronics, University of Benin, Edo State, Nigeria. E-mail: engrshoewu@lasunigeria.org* ABSTRACT In this paper, the development of an attendance management system using biometrics is proposed. Managing student attendance during lecture periods has become a difficult challenge. The ability to compute the attendance percentage becomes a major task as manual computation produces errors, and also wastes a lot of time. For the stated reason, an efficient attendance management system using biometrics is designed. This system takes attendance electronically with the help of a finger print device and the records of the attendance are stored in a database. Attendance is marked after student identification. For student identification, a biometric (fingerprint) identification based system is used. This process however, eliminates the need for stationary materials and personnel for the keeping of records. Eighty candidates were used to test the system and success rate of 94% was recorded. The manual attendance system average execution time for eighty students was 17.83 seconds while it was 3.79 seconds for the automatic attendance management system using biometrics. The results showed improved performance over manual attendance management system....

The computer processing idea has been around for hundreds of years but the equipment has only been available for the past several decades evolving to become better with each step. The need for a formal system to record and identify first-time and repeated offenders in the 1800s led the known Bertillon to develop anthropometrics to identify individuals. This advancement was later linked with computer systems to create a true biometric system identifier. The several types of biometric identifiers, later discussed, have evolved from a mere idea to an implemented security system used in airports, government programs, and even small businesses. The technology is used globally from the US to the UK, India, Germany, and many more. Its long history has created responsiveness and allowed countries to embrace the welfares of such a...
