Digital Water Marking for Digital Anti-forgery Applied Research
一种数字水印在数字防伪中的应用研究*

This paper analyzes the digital watermark rationale,contrastes several kinds of commonly used digital watermarks algorithm.The paper introduces the Arnold digital image set at chaotic and the principle of inverse transformation return to original state.The algorithm feasibility and the toughness are carried out by Matlab.Finally,this paper realizes a digital watermark model based on Inter the OpenCV class and the Arnonld transformation.
