Using SFLA and LSB for Text Message Steganography in 24-Bit RGB Color Images
2013
A B S T R A C T In this study, we intend to increase the robustness of text message steganography by hiding the message in appropriate places of image. Due to it, shuffled leaping frog algorithm (SLFA) is used to search among blocks of image data for similar ones in message. The SLFA is a memetic meta heuristic that is designed to seek a global optimal solution by performing a heuristic search. Experimental results of applying the proposed method on 20 sample images shows the appropriateness of method. Also, some parameters like the length of data blocks are discussed which play an important role in efficiency of proposed algorithm.
