摘要
提出一种基于多维关联度的数字证据链自动构造方法.首先设计一种数字证据标准化表示方法,将数字事件与其之间的关联关系进行规范化描述.然后通过对数字事件关联关系的分析,提出多维度的非因果关联度计算方法和基本证据环的构造方法,对数字事件因果关系进行深度分析.实验结果表明,所提出方法构造的数据证据链对于提升数字证据的证明力具有一定的应用意义.
Abstract
An automatic construction method of digital evidence chain is proposed based on multi-dimensional correlation degree.First,a standardized representation of digital evidence is designed to standardize the description of digital events and the correlations between them.Then,by analyzing the association relationship of digital events,a multidimensional non-causal correlation degree calculation method is proposed for the construction of the basic evidence ring,and a deep analysis of the causal relationship of digital events is conducted.The experimental results show that the data evidence chain constructed by the method has certain application significance for improving the proof power of digital evidence.
