摘要
保护数字产品版权,抑制盗版是数字指纹所关心的主要问题。本文简要介绍了q-进制数字指纹的概念及其相关结果,并且在此基础上提出了一种新的q-进制指纹的概念,进而利用纠错码构造了一种性质优良的q-进制防诬陷码。
It is the focus of digital fingerprints to protect the copyright of digital products. This paper first introduces some basic concepts and results of q-ary digital fingerprints, and then develops a new concept for q-ary fingerprints.
