AB  - Although recent development in Internet technology has brought many benefits to our lives, numerous dysfunctions, such as Internet-based cybercrime, have also increased. In order to effectively investigate such Internet-based cybercrime, it is essential to collect, store, and process cyber public information from a digital forensics perspective. However, related laws, such as the current Criminal Procedure Act, have not yet explicitly stipulated cyber public information forensics, or deletion of the original data, may also be one of the reasons for this occurrence. In this paper, we propose a novel architecture in processing and disclosing cyber information forensics tool for investigation to secure the legal evidence capability of cyber disclosure information collected between effective investigations and investigations of cybercrime. We also present a technical approach from a digital forensics perspective to demonstrate the integrity, identity, reproducibility, and authenticity of digital evidence to be observed while collecting and storing cyber disclosure information using the proposed tool.
