Enormous usage of multimedia necessitates maintaining a secured environment. Security in multimedia communication can be achieved with many cryptographic techniques. Perceptual video encryption is an essential technique to prevent the unwanted use of the video which is transmitted. Encryption is used in order to maintain a safe content of data from attackers. This paper explains about the perceptual video encryption using SPIHT (Set Partitioning in Hierarchical Tree) transform. It achieves good PSNR values and it is more secured to transfer videos.
