摘要：In this paper a fuzzy logic approach is introduced to embed the encrypted watermark in the wavelet domain. The multi-resolution representation based on DWT incorporates a model of Human Visual System (HVS). Encryption and digital watermarking techniques need to be incorporated in digital right management. It is clear that these two technologies are complimenting each other, and the complete security of the digital contains depends on both. Encryption transforms the original contain into unreadable format and watermarking leaves the digital object intact and recognizable. The objective is to develop simple, real time and robust secure watermarking system, which can be achieved through the hardware implementation. To meet a real time constrain we have proposed parallel computing architecture for wavelet transform. The experimental results demonstrate the high robustness of the proposed algorithm to various attacks like noise additions etc
