Since multimedia data contains important as well as personal digital images and videos so, their storage, privacy and security are the most important issues while transmitting data openly over the network. In this work, firstly an image has been encrypted via prediction error clustering and random permutation. Then the encrypted image has been compressed using both HAAR and COIFLET wavelet using 2D level of decomposition. Finally, the results have been compared on the basis of different parameters: Compression Ratio (CR), Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR), Entropy, Bit Error Rate (BER) showing HAAR wavelet is better than COIFLET wavelet.
