Multimedia contents have received a sharp attention now a day as a result of massive development of cyber crime. Illegal replication, violation of authentication, misappropriation of digital content has achieved an enigmatic growth. In this respect we’ve already proposed different schemes for invisible watermarking for color image authentication in fragile domain. In current communication we are going to propose a chip-based framework for color image authentication in accordance with our prescribed LSB scheme. In this watermarking scheme, a secret key will be given to the user and with the help of a particular hash function the user can authenticate the ownership of an image. With the aforesaid secret key and hash function the secured communication is guaranteed. The original watermark will not be retrieved if any intruder tries to perform watermark extraction with an inappropriate key and a incorrect hash function. We named our proposed chip as BLIND CHIP, because we’ve used blind method for watermark extraction where neither the host image nor the watermark image is needed at the time of watermark extraction.
