AN OVERVIEW AND APPROACH FOR HYBRID IMAGE ENCRYPTION AND COMPRESSION

Abstract

In an image processing, for proving security to an image many encryption techniques are available. But most of the Encryption techniques mask some amount of data to the source image that always increases the size of image. Encryption makes it difficult to transmit an image through bandwidth constrained channel. To overcome this problem, Image Compression can be applied on the Encrypted image to reduce its size. This paper presents the analysis and overview of some prominent approaches which are relevant to the image encryption and compression. It also discusses an approach to perform joint encryption and compression on image. The scope of implementation for the derived idea exists. Some analytical analysis is also presented from the proposed approach implementation point of view.
