Abstract |
Steganography is one of the data security methods to hide the secret information within the cover medium. Steganography is advantageous than other data security methods like cryptography because the hidden information is not predictable. In this paper, we propose a steganography model in which data is embedded in the discrete cosine domain of cover image. This model provides high data embedding capacity and better data invisibility which describes the efficiency of a steganography model. In the proposed model, the secret image is coded into binary bits using Huffman coding and then they inserted into the DCT domain of the cover image. It differs from other DCT based steganography method in terms of data embedding algorithm. |
