A New Approach of Crypto-compression on MPEG Format

Abstract

Issues of security and compression of transmitted data have become an important concern in multimedia technology. In this study, we propose an efficient approach to secure video sequences in real time using the method of choosing reference images that is based on the Faber-schauder Multi-scale Transform to reduce the data flow. The encryption step is based on the principle of affine encryption to achieve transposition and to perform some manipulations such as puzzle to reduce the amount of bits to be processed on the image. Testing this approach on video sequences revealed an improvement in data flow and provides a stronger security and a good encryption time.
