Abstract:

A novel image blind digital watermark algorithm is proposed. When using error correcting coding and Arnold transform, the binary image watermark is processed before embedded into the bitplane of the original gray image. It is effective to improve the security of traditional least significant bits (LSB ) watermarking algorithm. The embed position is chosen by the secret key which is obtained during the course of the best scrambling degree calculation in Arnold transform. This algorithm can also realize blind extraction of digital image watermark. The experimental results show that the watermarks are invisible and robust against noise and commonly used image-processing methods such as Gaussian’s noise, Salt Pepper noise, joint photographic experts group (JPEG) compressing, and crop procession etc

Key words: watermarking, Arnold transform, error correcting coding, least significant bit
