Abstract

Biometric fusion image (BFI) help increase the accuracy of identity authentication system. Previous study shows that a higher level of accuracy of recognition ratio can be achieved by employing the two dimensional Fisher Linear Discriminator (2D-FLD), a method for fusing and extracting biometric images [1]. However, in this paper, we have extended 2D-FLD method to fuse and extract biometric images then we are able to share BFI over unsecured communication network, provided that a secret code has been embedded. The secret code method using the pseudo-random sequence in order to secure the shared images between the owner and clients over satellite communications is proposed. Results indicate that the recognition rate of the transferred image is in the range between 93% and 100% at the receiving end.
