摘要：A buyer-seller watermarking protocol utilize watermarking along with cryptography for copyright and copy protection for the seller and meanwhile it also preserve buyers rights for privacy. Up to now many secure BSW protocol has been suggested but the common problem with all of them is that in all of them is the buyers involvement in generation of some cryptographic key or watermark or digital signature what happened if buyer is not capable or is a layman and does not understand what cryptography and watermarking means. In this paper we proposed the use of open access identification concept for this buyer has to get registered with some trusted third party which after registration provide an open access ID which is unique. This not only provide anonymity to buyer but the seller can also provide some benefit to his loyal customers. In our scheme non of the watermark or cryptographic key is generated by buyer so a layman buyer can also use it. It also enables a seller to successfully identify a malicious seller from a pirated copy, while preventing the seller from framing an innocent buyer and provide anonymity to buyer.
