ADAPTIVE ON DEMAND SIZE BASED IMGAGE STEGANOGRAPHY WITH CIPHER TECHNOLOGY

Abstract

The improvement of spending internet system has enlarged the cosiness of data communication which throws competition in information security. Now recent day’s not hurtful and nontoxic data broadcasting become more vigorous and substantial. In our recommended work the plain text is changed to a cipher text using the method of Cryptography, where individual can able to use their desirable key for encrypting the text and also some Boolean algebraic operations are used in the following steps and next this cipher text is suppressed inside a cover media of 2n x 2n dimension gray scale image and a secure pictorial block steganography grounded encryption algorithm is suggested for transporting message and also exposed the Steganalysis and Cryptanalysis technique for retrieving data at receiver side. The investigational result specifies that for using altered length of message text, distortion of picture is too much less which is negligible in open eyes. At the end it can be declared that deprived of knowing the proper knowledge of cryptanalysis and steganalysis regaining of message is quite impossible.
