Method To Enhance The Capacity Of Embedding Data In Jpeg Images
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2016, Vol 5, Issue 2
Abstract
A novel method of reversible data hiding is proposed here. The technique relies on data hiding in encrypted JPEG images is used. As we know that encryption is an effective method of privacy protection .All previous method such as embedding using a difference expansion method produce some error on the recovery stage and their embedding capacity is relatively small compared to the proposed method. In this paper, we take an image and it is compressed and later it is encrypted .To this image the secret data are embedded to it and again it is encrypted using another key called embedding key. Reaching the receiver side if he has only the both key he can obtain initial image otherwise only partially restored image and secrete data that embedded in it will not be retrieved.
