In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.
