基于证据链的电子证据可信性分析

随着信息技术的普及与应用,计算机已经成为了人类生活的必需品,同样也成为了犯罪活动中必不可少的工具。计算机留下的电子证据通常会成为案件侦破或审判的核心证据。但是,由于电子证据的易失性和易篡改性,导致其经常在法庭上遭到质疑,因此证明电子证据的可信性是当前取证领域面临的一大挑战。提出的基于证据链的电子证据可信性分析模型通过构建证据链获取关联电子证据 ,并通过判断证据间一致性的方法,进行推理获得电子证据的可信性。

Trustworthiness Analysis of Digital Evidences Based on Chain of Evidences

Computers are necessary in our lives along with the popularization of information technology,and they are also important tools in criminal activities.Digital evidences often play a major role in the judicial case or trial,but digital evidences have usually been questioned in the courts because they are easy to forge.To prove the trustworthiness of di-gital evidences is a big challenge of forensic research.In this paper,we put forward a framework to analyze trustworthiness of digital evidences based on chain of evidences by means of building chain to access associated evidences and ju-dging the consistency among evidences to deduce the their trustworthiness.
