With the continuous progress of science and technology, the Internet has gradually entered every field of daily life. In addition to the information generated by the Internet in the form of digitization, it has become the main media for people to store information. In the field of criminal offenses, the network is likely to be used to perpetrate criminal schemes, implement crimes, or help hinder investigations afterward. These acts will leave an electronic data trail, such as WeChat information, emails, or blogs. After a crime occurs, an evidence investigator should accurately, timely, and comprehensively obtain all electronic data related to the case by collecting, extracting, and transferring this data according to the law, and examining the authenticity, legality, and relevance of the evidence. Through a comprehensive review, the investigator should clarify the relationship between the electronic data and the facts to be proved and make full use of the obtained electronic evidence in criminal proceedings.
