| Popis: | 98 More and more customers purchase digital contents through the Internet due to its b popularity and convenience. However, there are a multitude of pirated editions of digital products that have become more available and easier to attain. Therefore, proving the legal ownership of digital contents has becomes more important than ever before. Many researchers have proposed various schemes to protect consumer''s ownership with watermarking mechanisms on secure payment systems. In this paper, we want to preserve customer’s ownership via subliminal message and propose an intact arbitration mechanism to solve the fairness of transactions between both the customer and the shop. In order to achieve above objectives, the security of this protocol employs five cryptographic techniques including the subliminal channel, Nyberg-Rueppel scheme, one-way hash function, Schnorr signature scheme and RSA cryptosystem. We propose two payment schemes: on-line payment system based on discrete logarithms problem and off-line payment system based on factoring problem. Our schemes not only protect customer’s legal ownership of digital content, but also achieve fair transaction, customer anonymity, owner tracing of coin and payment security. |
