Abstract

In this paper, we propose a perceptual video encryption algorithm that utilizes rotation matrix and unit anti-diagonal matrix to visually degrade video data with varying perceptibility. Blocks of pixels in video frames are identified and extracted using rotation matrix and encrypted/decrypted using unit anti-diagonal matrix. Analysis of results show that the technique has low computational overhead and ideal for on-the-fly encryption. When compared with existing techniques, the proposed method is better in the quality of visual degradation, processing time and independent on the video format. Preliminary analysis also showed that the proposed method can resist chosen/known-plaintext attacks.
