HARDWARE REALIZATION OF A NOVEL LSB STEGANOGRAPHIC ALGORITHM

摘要：

Steganography is the science of hiding information by embedding messages within cover medium so that the existence of the message is concealed.LSB is the most common method of image steganography that represents a high embedding capacity but it is detectable by statistical analysis such as RS and Chi-square analyses.Therefore, a novel LSB algorithm proposed that can effectively resist image steganalysis based on statistical analysis.This paper, proposes a hardware realization of this new algorithm which is designed for one to four bit insertion.Furthermore, a novel combinational message bit randomizer is designed for security improvement.
