Steganalysis of Real Time Image by Statistical Attacks

Free registration required

Executive Summary

Steganalysis is a technique for the detection of the secret information's embedded in the another image known as cover image and if possible the secret text is tried to recover .In this paper, two techniques are used for the detection of the hidden data .Firstly, detection done by comparing the histogram of the stego & cover image in which the attacker knows about the cover image without the knowledge of the coding algorithm of the stego image & secondly in the image smoothening technique, the probability distribution function is used for the detection .Based on the difference in statistical parameter of the stego image with cover image detection is done.
