Practice of Video Encryption Algorithms Based on Chaotic Sequence and Scan Pattern

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 4693)

Abstract

In this paper, we propose a new method of digital video encryption based on the SCAN methodology that is a formal language-based two-dimensional spatial accessing methodology, which can generate very large number of scanning paths or space filling curves. The SCAN-based video encryption is first performed by detecting the difference between adjacent frames and compressing these frame differences, and finally the encrypted video is obtained by encrypting the above frame differences. The main characteristics of the proposed methods are image encryption, which can be bounded pixelwise by a user specified value, very large number of encryption keys, and the ability to encrypt large blocks of any digital data. The simulation with standard color test videos (Tennis) indicates that the proposed encryption algorithm can achieve satisfying results. In the end, the characteristics and effects of the algorithm are summarized and the aspects of the subsequent work are prospected.
