Abstract

Strongly multimedia identifiable parent property code (t-SMIPPC) was introduced for protecting multimedia contents from illegally redistributing under the averaging collusion attack. Such a code has efficient algorithms for tracing colluders. However, there are few results about the existence of such codes up to now. In this paper, we focus on t-SMIPPCs with length $t+1$ where $t \ge 2$ is an integer. We first improve the lower bound on the size of such codes. For the case $t=2$, i.e., 2-SMIPPCs with length 3, we further investigate combinatorial properties of the codes. Based on these properties, optimal q-ary 2-SMIPPCs with length 3 are constructed for $q\equiv 0,1,2,5 \pmod 6$.

长度为 $$t+1$$ 的 t 强多媒体 IPP 编码的构造

强多媒体可识别父属性代码（t-SMIPPC）被引入用于保护多媒体内容免受平均串通攻击下的非法再分发。这种代码具有追踪串通者的高效算法。然而，到目前为止，有关此类代码存在的研究成果还很少。在本文中，我们关注长度为 $t+1$ 的 t-SMIPPC，其中 $t \ge 2$ 是整数。我们首先改进了这种编码的大小下限。对于 $t=2$ 的情况，即长度为 3 的 2-SMIPPCs ，我们进一步研究了编码的组合特性。基于这些特性，我们为 $q\equiv 0,1,2,5 \pmod 6$ 构造了长度为 3 的最优 qary 2-SMIPPCs 。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
