Abstract: With the progress in data exchange today communicators are not only facing the problem of security, but also the speed of communication and size of content. Digital images in their uncompressed form require an enormous amount of storage capacity which in turn needs large transmission bandwidth. Image compression reduces the storage space of image & also maintains the quality of image. Encrytion techniques protects the confidential image data from unauthorized access This paper focus on dual approach of compression and encryption where compression is achieved through DCT and DWT(Haar wavelet transform) and compressed image is encrypted using Deblurring technique. Moreover ,the compression approach applied to encrypted image is proved more efficient in terms of Compression Ratio(CR),Mean Square Error(MSE),Peak Signal to Noise Ratio(PSNR).For the implementation of this proposed work we use MATLAB software.
