Abstract

Security of a cryptographic system depends much on the randomness of random number used in the system. In this paper, a true random number generator based on the data of fingerprint (FPTRNG) is designed which extracts the random information from image data of fingerprint to generate random number. The random number generated by the generator is tested using the statistical test suite for random and pseudorandom number generators of NIST. Test result shows that the random data generated by this random number generator has perfect randomness. In fingerprint-based information security system, FPTRNG insures higher level of security.
