Encryption System Integrated with ROI and Tracking for High Efficiency Video Coding
Ximing Cheng, Houqiang Li · 2014
In this paper, we present a novel encryption scheme that integrates Region of Interest (ROI) tracking on the next generation High Efficiency Video Coding (HEVC) standard. With the Tracking Learning Detection (TLD) algorithm, the ROI encryption system can become more intelligent through constrained motion estimation and some constrained mode decision. The encryption system we proposed on the selected bin strings in Context Adaptive Binary Arithmetic Coding (CABAC) of the HEVC can achieve an obvious encryption performance improvement on different situations. With the RSA and key management scheme, the security of our encryption system is fully guaranteed.
