Abstract: |
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 is detailed, and a cascaded Radon projections technique is derived for high security selective encryption. The proposed technique enables fast encryption of a large amount of digital data. Standard encryption techniques, such as AES, DES, 3DES, or IDEA can be used to efficiently encrypt high resolution images. As the proposed scheme uses standard encryption, and only transmits uncorrelated data along with the encrypted part, this technique is very secure, therefore, we hereby assess its performances in terms of processing time and compression ratio. |
