An Analysis of Lightweight Encryption Schemes for Fingerprint Images
Dominik Engel, Elias Pschernig, Andreas Uhl · IEEE Transactions on Information Forensics and Security · 2008
Two lightweight encryption schemes for fingerprint images based on a bit-plane representation of the data are assessed. We demonstrate a low complexity attack against a scheme recently proposed in literature which exploits one of several weaknesses found. A second scheme is evaluated with respect to two fingerprint recognition systems and recommendations for its safe use are given.
