Detailed Description
Embodiments of an evidence preservation platform based on content data parsing according to the present invention will be described in detail below with reference to the accompanying drawings.
Electronic evidence collection refers to a process of obtaining, storing, analyzing and presenting evidence of criminal behaviors such as computer intrusion, destruction, fraud, attack and the like in a manner of meeting legal specifications by using computer software and hardware technologies. From the technical aspect, computer crime evidence obtaining is a process of scanning and cracking an invaded computer system and reconstructing an invaded event. Specifically, the method regards a computer as a crime scene, and utilizes advanced discrimination technology to dissect crime behaviors of the computer and search criminals and crime evidences thereof.
With the increasing number of crime cases and the digitalization of crime means, the work of collecting electronic evidences becomes a key to provide important clues and solve cases. Electronic evidence is the restoration of corrupted computer data and the provision of relevant electronic data evidence.
Due to the particularity of the electronic evidence, when collecting the electronic evidence, a computer operator who provides an evidence unit needs to open the computer to search the evidence which needs to be collected. When evidence is found, the forensics should view and confirm the time of formation of the document through the display. Then the operator opens the file, and the evidence collector determines that the file is the evidence to be collected, and then extracts and fixes the file in a corresponding mode. In the process of finding evidence, if the document can not be found or opened, the professional should be informed in time to assist. Meanwhile, in order to ensure the originality, authenticity and legality of the electronic evidence, professional data copying and backup equipment is adopted to copy and backup the electronic evidence file during the collection of the electronic evidence, and the data copying equipment is required to have the functions of read-only design, automatic calibration and the like.
