Construction method of digital evidence chain driven by multidimensional correlation analysis
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.
