Research of key technical issues based on computer forensic legal expert system

摘要

The research field of legal profession includes related legal features of computer evidence and its recognition process thereof. Evidence technical features and acquisition techniques thereof are researched and calculated from technical angle in computer field. Since forensic discipline belongs to an inter-discipline established on the basis of law and computer science. It should be researched from the perspective of the two disciplines and specialty embodied on the derived disciplines thereof. In the paper, effectiveness of economic contract and risk consultation during performance are proposed, and legal expert system design model for legal retrieval is established with limited natural language. The system is realized with blackboard model. A knowledge expression method applicable for legal field is also proposed. Law is combined with computer technology for researching computer forensics. Related legal issues of computer forensics are described. Technical methods and tools for computer forensics are mainly researched, and a technical process of computer forensics experiment is provided. Current related laws and regulations of computer forensics and disadvantages of computer forensics technology are proposed. Keys of exchange safety under network environment are discussed with information exchange theory. Existing information laws are analyzed. Establishment of new network safe legal system is proposed from the perspective of information exchange. Finally, the system is designed and realized, and key issues are studied.
