316 www.ijergs.org A REVIEW ON KEYLESS APPROACH TO IMAGE ENCRYPTION

Abstract – How data can be shared from one part of the world to the other in near real time came with the arrival of internet. Along with this they have introduced new challenges like maintaining the confidentiality of transmitting the data. This gave a boost to the research area related to cryptography. Firstly, Encryption of images with the accepted encryption algorithms had significant downside as key management was complicated and limited. Secondly, introduction to new area for encrypting images was splitting the image at its pixel level in to multiple shares. But the major drawback of this approach was that the recovered image had a poor quality. To overcome these mentioned drawbacks we have proposed a new approach which does not attempt to use any type of keys for encryption
