BIOMETRIC FINGER PRINT IDENTIFICATION BASED SECURITY SYSTEM.

Nowadays accurate personal identification is becoming more and more important.Usual means (smart cards, passwords…) have shown their limits (falsification, loss…).Biometrics (i.e. analysis of personal biological characteristics) can bring a satisfying answer to those latter problems. Currently fingerprint recognition is the most widely used techniquefor personal identification. Fingerprints are made up of locally parallel ridges with singular  points (minutiae), and they constitute a unique permanent universal pattern. The use of ink and paper to get an image from a finger was used for a long time, but technological advanceshave enabled to automate the acquisition stage by means of solid-state sensors. These sensorsexploit different techniques to acquire the image (pressure, electrical field, temperature…)and require a static (matrix sensor) or mobile finger position (sweeping mode sensor).Our project is developed to provide security for a Organization. In this project thefingerprint sensor sense the thumb impression of the corresponding person and that imagewill be compared with registered image, if the both images are unique, then the finger printdevice activates particular task like access control to a secured area, identification of theemployee etc. The project contains 2 modes, the first one is master mode and the second isuser mode. The master mode is used to register the new user and gives the mode of authorization. The master mode has the ability to create and delete the users. The user modeis an ordinary mode used for the authentication of the employees. In user mode of authorization, creation and deletion of a user cannot be performed.The Master mode operations are done directly through interfacing the FM10(Finger Print Module) to the COM PORT of the computer. The application program isdeveloped using java API in Swings. The Java communication API is used for communicating with the Fingerprint device. The employee details along with biometricinformation database is stored in the flash memory of the Fingerprint module. TheMicrocontroller 89S52 is programmed to operate under user mode. Microcontroller is programmed using C51 cross compiler. Fingerprint image is scanned by the fingerprintdevice. If the scanned image matches with the registered image then Microcontroller sendsthe authorized persons Id to the computer when the person enters and leaves the organization.By this daily attendance of employees, many employee records are maintained. Theemployee records are stored in the database
