Combine use of Steganography and Visual Cryptography for Secured Data hiding in Computer Forensics

Abstract

The proposed system highlights a novel approach for creating a secure steganographic method and visual cryptography for data hiding in computer forensics. Although there has been an extensive research work in the past, but majority of the research work has no much optimal consideration for robust security towards the encrypted image. The proposed method encodes the secret message in least significant bits of the original image, where the pixels values of the encrypted image are modified by the genetic algorithm to retain their statistic characters, thereby making the detection of secret of message difficult. Use of Genetic algorithm has compelled the system for enhancing the security. The proposed system hides data in a real image and achieve its detection after under went to visual cryptography. The main aim of the proposed model is to design a feasible RS- resistance secure algorithm which combines the use of both steganography and visual cryptography for improving security, reliability and efficiency for secret message. The implementation is done in java platform which shows that the proposed system has better resilienc by considering the steganalysis.
