Abstract: Hamming code and Arnold shuffling techniques are used in this paper. A method of image content tampering recovery based on correct-encode combined with the LSB is proposed. The original feature of image is picked up to generate correct code, which is embedded into the original image after being changed with Arnold shuffling techniques. When the watermarking image is tampered, the original feature can be recovered by the correct-encode which is picked up from the image. Experimental results show that proposed algorithm can detect and local the tampered areas effectively, and it has a good self-recovery function.
