Lossless and Reversible Data Hiding using Public Key Cryptography

Abstract

In today’s world, the internet is a platform, where large amount of data can be obtained and transferred. Different technologies and internet access are used to transfer the data which can be accessed by authorized and unauthorized users.The major drawback of these technologies are that any unauthorized person can access it.Hence encryption and decryption is perform on Message/Data .In encryption the plain text/image is converted into cipher text/image.The technique of data hiding is used to hide the data that has to be transferred from the source to the destination.The process involves insertion of secret message in the cover image which is encrypted with the help of AES algorithm. This algorithm generates public/private key. All this process can be performed in lossless and reversible manner.
