Data flow diagram for attendance monitoring with finger print scanner

Termination of a fingerprint is simply the situation in which a particular ridge ends abruptly while bifurcation is the situation by which the line splits into two.

While the second module covers security duties. It starts with the taking of the finger print; the template of the finger print taken is extracted. All these maintenance practices should be done on a regular or semi-regular schedule, often during non-peak usage hours, and keep servers running smoothly. Architecture focuses on looking at a system as a combination of many different components, and how they interact with Data Flows: each other to produce the desired result. The Architectural design of fingerprint biometrics verification and vetting management system is shown in figure 3. Attendance Management System AMS is the easiest way to keep track of attendance for organizations such as industrial organization, business organizations and volunteer groups. In case of fingerprint images Tp represents the imbalance in intensity between the back-ground pixels and ridge pixels. Normalisation Normalization operation acts on the input fingerprint image to standardize image pixel intensity values. Therefore, it was appropriate to use Gabor filters as band pass filters to remove the noise and preserve true ridge and valley structures [14]. The registration page links directly with the admin page, the admin has the privilege of seeing the details of every registered user and the page displaying attendance information of all users. Security vetting process requires the total in biometric system, input fingerprint image is processed to skeleton image levels and then features are extracted from the said thinned image.

Figure 2 shows activity diagram of the proposed system. Ridge pixel values are then classified as ridge ending, crossover, bifurcation, isolated points and crossing points as illustrated in the figure 6.

The Level 1 DFD shows how the system is divided into sub-systems processeseach of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the system as a whole.

When human fingerprint experts KeyWords: Fingerprint Identification, Attendance determine if two fingerprints are from the same finger, the Management. Top down design approach was employed which involved dividing the system into subsystems or modules and each subsystem being further divided into even smaller subs. Crossing Number Minutiae extraction techniques 7. It can be concluded from the above discussion that a reliable, secure, fast and efficient system has been developed replacing a manual and unreliable system. Finally, a simple image scans allows the detection of pixels that correspond to minutiae through the pixel-wise computation of crossing number. The class diagrams are widely employed in the software modelling of object oriented systems because they are the only UML diagrams which can be mapped directly with object oriented languages [8]. Adewole, S. The system was developed to enhance security in the nation. The system was developed to manage attendance record in an organization using the available computer development tools.

Net environment. The term biometrics is derived from the Greek words bios meaning life and metron meaning measurement [2]. Fingerprint verification process Figure 8.
