Abstract:
Fingerprints as a type of biometrics, appear to be the most populous and most acceptable means of individual identification and verification. We leave our fingerprints on virtually anything we lay our fingers on. The chance however, of casually leaving our fingerprints at several location without our knowledge, exposes mankind to much more insecurity. The biometric templates identifies us as those imprint features they get from our body, thus; losing them by any sort means losing who we actually are. In this paper, protection of biometric (fingerprint) template is an important issue that was dealt with. The protection of fingerprint in the database of the Automatic Fingerprint Identification System (AFIS) using a modified Gaussian equation to encrypt the image and store as template in the database and decrypt the template to compare with the reference data during verification. This technique of encryption successfully encrypt and decrypt without degrading the original image sample. The simulation of the image was carried out on a MATLAB environment whereas the verification was performed using the GrFinger environment.
