The document discusses fuzzy logic in watermarking systems. It provides an overview of watermarking, encryption, fuzzy logic, and fuzzification/defuzzification. It then discusses how fuzzy sets can be used to design the front-end of a watermarking system, with fuzzy sets defined for factors like robustness, encryption algorithms, and watermarking methods. The front-end architecture is designed based on fuzzy rules to provide a more user-friendly interface. In conclusion, this approach can make software architecture design easier by incorporating user-defined fuzzy sets and rules.
