A New Fast Reversible Method for Image Safe Transfer (2007)

Puech, William, Rodrigues, José, Develay-Morice, Jean-Eric

In this paper a novel reversible method for fast and safe image transfer is proposed. The method combines compression, data hiding and partial encryption of images in a single processing step. The...

Analysis and Cryptanalysis of a Selective Encryption Method for JPEG Images (2007)

Puech, William, Rodrigues, José, Bors, Adrian

This paper addresses the protection of images. We address the problem of simultaneous selective encryption (SE) and image compression. The SE is done by using the Advanced Encryption Standard (AES)...
