Abstract:

This paper reviews the up-to-date research results in the analysis of information-hiding capacity, and establishes the communication model of informat  ion-hiding. With the description of the theoretical question of hiding capacity, we classify the capacity analysis results given. We particularly analyse the expression of capacity results and provide some new viewpoints and four important aspects for further research.

Key words: （information hiding, digital watermarking, capacity analysis, digital fingerprint）
