数字指纹识别是一种用于识别出于非预期目的（例如重新分发）使用多媒体内容的用户的技术。为了表征能够抵御共谋攻击的指纹，Dittmann 等人。等人提出了反共谋代码（ACC）的定义。在本文中，我们提出了一种基于无覆盖家庭构建反共谋代码的新方法。之前所有ACC的建设都是我们建设的特例。特别是，我们可以通过使用纠错码来构造 ACC。不同方案的抗共谋性比较表明，我们的方案比以前的 ACC 更有效。提出了与此主题相关的一些问题。
Digital fingerprinting is a technique for identifying users who use multimedia content for unintended purpose, such as redistribution. In order to characterize the fingerprints that can withstand collusion attack, Dittmann et. al proposed the definition of Anti-Collusion Codes (ACCs). In this paper, we present a new approach to construct anti-collusion codes based on cover-free families. All the previous constructions of ACCs are special cases of our construction. Especially, we can construct ACCs by using error-correcting codes. Collusion resistance comparison of different schemes show that our scheme is more efficient than previous ACCs. Some related problems on this subject are proposed.
