ADAPTIVE IMAGE STEGANOGRAPHY USING PIXEL INTENSITY DIFFERENCE
Main Article Content
Abstract
In this digital world the Internet has become so popular and billions of people are using it. On various platform, web applications as well as standalone applications there is a need of Internet. For this purpose various techniques like cryptography, data encryption/decryption, and data hiding algorithms are invented. But use of these techniques was not too secure and hackers easily stole the secret message. To ensure high security of confidential data a new technique was invented known as “Steganography”. In this paper we a new a new steganography scheme which is very efficient with respect to data hiding capacity and distortion. The main approach for this algorithm is based on pixel intensity difference.
