In this paper we have proposed novel hardware for an adaptive encrypted watermarking method based on fuzzy logic. Fuzzy logic is used for data fusion, and it builds a human visual system (HVS) model for spatial masking in a wavelet domain. Encryption and digital watermarking both techniques must be incorporated to give best solution for digital rights management. It is obvious that these two technologies complement each other, and are both responsible for complete security of the digital information. Encryption transforms the original content into an unreadable format and watermarking leaves the digital object intact and recognizable. The aim of hardware assisted watermarking is to achieve low power usage, real-time performance, reliability, and ease of integration with existing consumer electronic devices. The experimental results demonstrate the high robustness of the proposed algorithm against the geometric distortion such as rotation and scaling.
