It was shown very recently in [1] that there are no multimedia digital fingerprinting codes capable of fully recovering a coalition of malicious users under the general linear attack and adversarial noise. We show that such codes exist if the class of attacks is narrowed to the averaging attack. The arising mathematical problem is close to the problem of constructing signature codes for a noisy binary adder channel.

抵抗平均攻击和对抗性噪声的完整可追溯多媒体指纹代码的存在与构建

最近在[1]中显示，还没有多媒体数字指纹识别码能够在一般的线性攻击和对抗性噪声下完全恢复恶意用户的联盟。我们证明，如果将攻击类别缩小为平均攻击，则存在此类代码。出现的数学问题接近于为嘈杂的二进制加法器通道构造签名代码的问题。
