P-集合与信息真度及应用

P-Sets and Information Truth Degree and Its Application

在P-集合的基础上,给出特征数据、(F,F)-特征数据集合的概念,提出特征数据迭代发现和消除定理、信息真度定理、信息真度距离定理和数据前后域恢复定理,给出数据的信息真度辨识准则,最后给出这些概念与定理在信息安全中的应用方法。

Based on P-set,the paper presents characteristics of data,concept Of（F^-,F）-feature data collection,proposes the detection and elimination theorems of iteration characteristics of data,information truth degree theorem,information true distance theorem,data recovery theorem before and after domain and truth degree of identification criteria of data.The paper finally presents the application of these concepts and theorems in information security.
