Digital watermarking techniques: theory, algorithm and future work

How to provide copyright protection and implementing covert communication has drawn extensive attention in recent years.As a main method for copyright protection(watermarking),digital watermarking has been studied and applied widely.In this paper.we present a summary on the digital watermarking techniques including the latest achievement in this field.First,we give the general concepts and fundamental principles of digital watermarking the definition,characteristic ,classification and general framework.Then,we analyze the processing model,the typical methods,the main application and the attack analysis of watermarking.Finally,we point out some possible orientations for the further research and the application prospect of the technique we make a discussion on some open problems and point out some possible directions for topics.
