- Abstract:
-
This study presents an overall introduction of a finger vain encryption algorithm. A finger vain encryption algorithm with error correction is then designed by adding an error correction mechanism. This new finger vain encryption algorithm can produce a stochastic key in the form of a multinomial coefficient using a binary system sequencer, an encrypt finger vain, and the Lagrange interpolation value to restore the multinomial during authentication. The accuracy of this algorithm can be ensured using the cyclic redundancy check the code to determine the most accurate key. The experimental results indicate that the fuzzy vault algorithm with error correction can realize well the encryption and decryption of a vein template and meet the requirements of biological information security protection. In addition, the algorithm also indicates that the syste’s safety performance can be enhanced by changing the keys’ length.
