This paper proposes a new format-compliant perceptual encryption scheme based on the Multiple Description Coding (MDC). The proposed technique exploits the scalable property of MDC which results in multiple encrypted formatcompliance video streams. An unbalanced MDC was specially designed to serve the purpose of perceptual encryption in such a way that it provides the control over quality differences and number of achievable qualities. In general, the perceived quality is directly proportional to the number of video descriptions that can be correctly decrypted. In order to preserve format compliant property of the encoded video streams, the proposed scheme was designed based on a pre-and post-processing multiple description video coding method and an encryption process at bit stream level. Hence, no alterations are required for both coding and encryption processes. Even though the proposed framework is format independent, this paper focuses on the H.264/AVC video coding standard. The experimental results demonstrate that the proposed scheme can successfully integrate encryption and a multiple description coding technique while preserving other multiple description video coding characteristics such as scalability and robustness.

The wide use of digital images and videos in various applications warrant serious attention to the security and privacy issues today. Several encryption techniques have been proposed in recent years as feasible solutions to the protection of digital images and videos. In many applications, such as pay-per-view videos, pay-TV and video on demand, one of the required features is that the quality of the video data be degraded only partially by some encryption technique and the encrypted data must still be partially perceptible. This feature referred to as 'Perceptual encryption' is the encryption algorithm that degrades the quality of media content according to security or quality requirements. In this work we propose a simple yet efficient technique for realizing perceptual encryption using geometric objects as kernels based on which the pixels are permuted. Confusion aspect that is required is realized by inserting the kernel on the image and thereby performing transposition of pixels based on the kernel formed out of geometric objects. The various parameters of geometric objects, number of objects and the position of the objects/kernel in the image
