Security and privacy issues of the transmitted data have become an important concern in multimedia technology. In this paper, we propose a computationally efficient and secure video encryption algorithm. This makes secure video encryption feasible for real-time applications without any extra dedicated hardware. We achieve computational efficiency by exploiting the frequently occurring patterns in the DCT coefficients of the video data. Computational complexity of the encryption is made proportional to the influence of the DCT coefficients on the visual content. On an average, our algorithm takes only 2 ms of encryption time per frame. This paper deals with the issues of color videos in-compression encryption, this done by using the optimized multiple Huffman table (OMHT) technique, will be elucidated upon in order to compress and encrypt both color images and videos. Only visual processing will be discussed (no audio processing). OMHT produces an encrypted coded sequence with an improved quality for the high compression ratios when compared to the existing standards in addition to the ability of encryption. The performance of the proposed technique is compared with that of the standard encryptions and it gives a very good perceptual quality especially at lower bit rates. We present experimental results which show that OMHT outperforms many traditional and selective techniques for video over wireless applications.
