(接上期)复杂模型在实际当中,我们碰到的假冒情况不太可能是单一的,往往可能遭遇数个假冒者,并且假冒的倍率也各不相同,因此我们有必要分析一下在这种情况下,数码防伪的有效性。我们可以将这种可能发生的现象通过建立以下的数学模型演示:假冒的数码有M个,第i数码的复制比率为Ci (Continued) Complex Models In practice, the types of counterfeits we encounter are unlikely to be single and often involve several counterfeiters, and the rate of counterfeiting varies from place to place. Therefore, it is necessary to analyze the situation in this situation Next, the effectiveness of digital security. We can demonstrate this possible phenomenon by establishing the following mathematical model: there are M fake digital numbers, the i digital digital copy ratio is Ci
