Design and Implementation of Image Steganography by using LSB Replacement Algorithm and Pseudo Random Encoding Technique

Abstract

Steganography is the efficient technique to provide secure data transmission over the network, as the number of users increases effectively. The cryptography is also used to provide security to data over network, but transmission of secured message may be detectable to third party. From security point of view, steganography does not allow to detect the presence of hidden secret other than indeed user, over the communication channel. Here we are implementing the image steganograpgy i.e image as the master file or cover media and secrete message can be text messages. This paper presents to provide the transfer of secret data embedded into master file to obtain new image , which is practically indistinguishable from the original image, so that other than the indeed user, cannot detect the presence of the secrete data sent. Here we use the Least Significant Bit (LSB) algorithm and Pseudo Random encoding technique for hiding the secrete data by embedding the secrete data into a master file in sending station and we use reverse process of LSB and Pseudo random encoding techniques during the retrieval of the secrete data from the master file by the intended user. The PSNR of both techniques should be measured as performance characteristics of the steganography and comparing both the techniques.
