我们提出了一种使用 Okamoto-Uchiyama 密码系统的新匿名指纹识别方案 [1]。在之前的方案[2]-[4]中，加密率是如此之小，以至于对于任何应用来说都很难实现。为了提高速率，我们在指纹协议中应用了 Okamoto-Uchiyama 密码系统。结果，买家可以匿名且高效地向嵌入数字内容的商家提交指纹，然后将加密数据量控制在合理的大小。在我们的方案中，买家和商家的安全也可以得到保护。
We propose a new anonymous fingerprinting scheme using Okamoto-Uchiyama cryptosystem [1]. In the previous schemes [2]-[4] the enciphering rate is so small that it seems very difficult to implement for any applications. In order to improve the rate, we have applied the Okamoto-Uchiyama cryptosystem for our fingerprinting protocol. 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.
