A Steganographic Method Using Tabu Search Approach

The steganography objective consists to hide confidential information within a cover-media in such a way that others cannot detect the presence of the hidden message. In this work we investigate to improve the embedding capacity and provide an imperceptible visual quality, using an adapted tabu search approach to locate the optimal positions of the pixels in the cover image. Experimental results showed that the proposed approach hide more large information and improve the quality of the stego-image.
