%X A new buyer-seller watermarking protocol without the third party was proposed,which used the idea of secret sharing and homomorphic public key cryptosystem.For a transaction,a piece of secret was produced by the buyer and the seller respectively,and the two pieces of secret were mixed into one secret in encrypted domain,which was embedded in a digital product as a watermark.The pirate tracing problem,the customer's problem and other problems can be solved by this watermark protocol.Meanwhile,the conspiracy problem can be completely avoided because of no the third party.
