A novel data hiding algorithm for game texture based on Hamming+1

Game texture image is an important resource in game development. In recent years, more and more attention has been paid to copyright protection technology in the computer game. Data hiding method can be used to add some secret messages in the game texture image. To solve the copyright protection of game texture image, a novel data hiding algorithm based on Hamming +1 technology is proposed in this paper. The secret messages are embedded into the modulation information of PVRTC (PowerVR Texture Compression) texture format which is popular in computer game. Due to the coding rules of the PVRTC texture format, the decompressed image quality will be reduced after secret messages are embedded. So the optimization mechanism is applied to improve the image quality. The experimental results show that this method is effective and can be applied to the copyright protection of the game texture images.
