A Video Sensing Oriented Format-compliant Entropy Coding Encryption Scheme and Embedded Video Processing System

A Format-Compliant Selective Encryption Scheme for Real-Time Video Streaming of the H.264/AVC

H.264 video coding standard is one of the most promising techniques for the future video communications. In fact, it supports a broad range of applications. Accordingly, with the continuous promotion of multimedia services, H.264 has been widely used in real-world applications. A major concern in the design of H.264 encryption algorithms is how to achieve a sufficiently high security level, whi...

Joint Entropy Coding and Encryption in AVS Video Codec

A data embedded video coding scheme for error-prone channels

We propose a novel data embedding scheme for fractional-pixel based video coding algorithms such as H.263 and MPEG-2. By modifying the motion estimation procedure at fractional-pel precision, two bits data can be embedded in a motion vector (MV) for a inter-mode coded macroblock (MB). For half-pel precision motion estimation, the resulted bitstream is compatible with the current video coding st...

A format-compliant configurable encryption framework for access control of video

– In this paper, we introduce new methods of performing selective encryption and spatial/frequency shuffling of compressed digital content that maintain syntax compliance after content has been secured. The tools described in this paper have been proposed to the MPEG-4 Intellectual Property Management and Protection (IPMP) standardization group and have been adopted into the MPEG-4 IPMP Final P...

Efficient and Format-Compliant Video Encryption Algorithm in Compressed Domain for H.264/AVC

In this paper, an efficient video encryption scheme is proposed for protecting H.264 bitstream. The issues on the compressed domain video encryption have been pointed out and fully addressed. In the proposed scheme, only the most significant bits for video reconstruction in H.264 bitstream are extracted and encrypted, to optimize the trade-off between security level and computational complexity...
