Lossless Image Compression and Selective Encryption Using a Discrete Radon Transform

Kingston, Andrew; Colosimo, S; Campisi, P; Autrusseau, Florent

Description

In this paper we propose a new joint encryption and lossless compression technique designed for large images. The proposed technique takes advantage of the Mojette transform properties, and can easily be included in a distributed storage architecture. The basic crypto-compression scheme presented is based on a cascade of Radon projection which enables fast encryption of a large amount of digital data. Standard encryption techniques, such as AES, DES, 3DES, or IDEA can be applied to encrypt very...[Show more]
