In the modern world, the privacy, security features and hidden information of the image is rapidly growing this lead towards the research interest. This paper proposes a new design of image encryption of an image using random permutation and then compression of an encrypted image using discrete wavelet transform. The main part of the work is the practical design of a pair of image encryption then compression. Compression process in this paper is similar to the normal compression of an image. The receiver side performs decompression and decryption. The decompression process by Inverse discrete wavelet transform and decryption process is the reverse of the encryption process. Thus image encryption then compression provides better security features and transmission rate.
