Information hiding technology is widely used in various fields, such as secret communication, digital watermark, forgery detection, etc. The paper proposes a method of information hiding based on wavelet transform, the procedures for hiding and extracting information are also presented in this paper. The method has good robustness and can resist some attacks such as lossy compression, noise, etc.
