Abstract

Abstract: Lossless data recovery can be achieved if we are able restore the original image without losing its state. It is possible in proposed system; the idea behind this is reserving space before encryption. By reserving space we can increase the payload as compared to existing system. We have use Histogram shifting for the data shrinking purpose; also it prevents underflow and overflow problems.
