Self adjustable security technique based on remote reference passing for digital multimedia services

摘要

In this paper, we have proposed parameterized security technique based on remote reference passing (RRP). RRP intrinsically works on the principle of transmitting the information or data in the form of reference at receiver side. RRP is most suitable technique to address security needs of video services while accessed/played through constrained devices because of its low power design and negligible delay during decryption process, one of stringent requirement of video transmission. Proposed technique has potential to offer varying level of perceptual encryption which makes it suitable to support different multimedia service with different security needs. This technique offer confidentiality and authentication for secure communication and further, same is also suitable for entertainment video services to facilitate pay TV, video on demand or pay per view. This technique encrypts the raw video in RGB 24 bit color space which makes its integration possible with different video codec.
