디지털 증거 인증시스템(DAS)을 통한진정성 입증에 관한 연구

Abstract

Digital evidence is a different form of evidence from the existing physical evidence due to the development of science and technology, and has always caused new attempts in our criminal law system. In particular, the method of search and seizure is defined as ‘principled selection seizure, exceptional storage media seizure’, and at the same time, it is defined to prove the authenticity of establishment by objective and scientific digital forensic. However, the authenticity of digital evidence has been solved through the Supreme Court precedent, not the Criminal Procedure Act. The precedent requires identity and integrity as a requirement to judge the authenticity of digital evidence. Although several methods of authenticity verification for digital evidence are suggested, this study introduces digital evidence authentication system (DAS) that certifies integrity using 해시 values of digital evidence. In addition, we suggest the plan for solving the authenticity problem of digital evidence by certifying immediately digital evidence collected in the investigation process through DAS.
