A NEW TECHNIQUE FOR DETERMINING REGION OF INTEREST IN SELECTIVE VIDEO PROTECTION APPROACH

Abstract

Today, the use of video communication in real-time applications is rising at a rapid rate and most of these videos require secure transmission like surveillance, video conferencing, video on demand, and medical and military imaging systems. The trade-off between data security and real-time performance is the main challenge in this field. This paper presents a protection approach for H.246 compression standard that provides a balancing between the security level and coding efficiency. A new technique of region selection for the motion information of the video is designed based on canny edge detection scaling which reduces the amount of encrypted data ,and a strong and fast stream encryption is presented using key generation model of chaos method and RC4 algorithm. The experimental results of the performance metrics confirmed the high perceptual and cryptographic security of the proposed approach against attacks and showed that all the requirements of compression efficiency are satisfied.
