| Abstract(in English) | We propose a new anonymous fingerprinting scheme using Okamoto-Uchiyama cryptosystem. In the previous schemes the enciphering rate is so small that it seems very difficult to implement for any applications. In order to improve the rate ingeniously, we have applied the Okamoto-Uchiyama cryptosystem for our fingerprinting protocel. As the results, a buyer can commit a fingerprint to a merchant being embedded in a digital content anonymously and efficiently, and then the amount of encrypted data is controlled in a reasonable size. The security can also be protected for both of a buyer and a merchant in our scheme. |
