Perspective Based Variable Key Encryption in LSB Steganography

Abstract

Abstract.We have explored a new dimension in image steganography and propose a deft method for image-secret data -keyword (steg key) based sampling, encryption and embedding the former with a variable bit retrieval function. The keen association of the image, secret data and steg key, varied with a pixel dependant embedding results in a highly secure, reliable L.S.B. substitution. Meticulous statistical analyses have been provided to emphasize the strong immunity of the algorithm to the various steganalysis methods in the later sections of the paper.
