A High Capacitive and Confidentiality Steganography Using Private key
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2011, Vol 1, Issue 1
Abstract
Steganography and Steganalysis are two important areas of research that involve a number of applications. These two areas of research are important especially when reliable and secure information exchange is required. To enhance the embedding capacity of image steganography and provide an imperceptible stego-image for human vision, a novel adaptive number of least significant bits substitution method with private stego-key based on gray-level ranges is proposed in this paper. The new technique embeds binary bit stream in 8-bits gray-scale image. The method also verifies whether the attacker has tried to modify the secret hidden (or stego-image also) information in the stego-image. The technique embeds the hidden information in the spatial domain of the cover image and uses simple (Ex-OR operation based) digital signature using 140-bit key to verify the integrity from the stego-image.
