An Uncompressed AVI Encryption Based on Haar Wavelet Decomposition of Frames and Audio

The privacy and security becomes the major issues since the multimedia is transmitted openly over the network. Along with the privacy and security, storage space is also an important point that cant be missed. So it is necessary to provide the privacy and security to the multimedia with help of encryption. This work presents design and implement of an efficient video encryption of uncompressed AVI system, where lossy compression is considered. The AVI (Audio Video Interleaved) file which is uncompressed divided into frames and audio which will be encrypted. Here a new modified International Haar Wavelet is used to encrypt the full video in an efficient secure manner, after encryption the frame and audio will be decomposes and deliver final uncompressed video. The proposed image encryption scheme operated in the prediction error domain is shown to be able to provide a reasonably high level of security and efficiency.
