An Image Based Encryption Algorithm for Multimedia Applications

Abstract

Multimedia is the most popular domain in recent era, where it handles distinct information such as text, image, music, video and etc. The security and channel capacity are the challenging parameters in real time multimedia applications. In this research work, an image based double encryption scheme has proposed along with DCT compression technique. The input image is encrypted by Chaotic Baker map and Advanced Encryption Standard (AES) algorithms. The encrypted image is compressed by DCT compression technique. The PSNR and MSE of proposed double encryption method attains 77.1617 and 0.0013 respectively. The experimental results are compared with the individual encryption methods shows that the performance of Double encryption is superior to the other existing methods.
