Abstract
We compare the performance of three selective SHVC encryption schemes: the first scheme encrypts only the lowest SHVC layer, the second encrypts all layers and the last scheme encrypts only the highest layer. The performance of the proposed schemes is assessed over different video encryption criteria, at different scalability configurations and various High Definition (HD) video sequences. Experimental results showed that encrypt only the lowest layer or all layers enables a high security level, while encrypting only the highest layer leads to a perceptual encryption solution, by slightly decreasing the highest layer quality. Moreover, the processing complexity of the proposed solution is assessed in the context of a real-time SHVC decoder. The complexity overhead remains low and does not exceed 6% of the real-time decoding of SHVC video sequences.
