Technical forensics has brought a certain degree of difficulty and challenge, on the other hand also promoted the computer forensics research and related technologies, tools to explore and improve. This reporter interviewed Xu Rongsheng, chief scientist of the Institute of High Energy Institute of Cybernetics, CAS which has a long history of research in computer forensics. He introduced in detail the development status and current status of Chinese and international evidence-based technologies and their problems. Journal will then launch a series of articles related to computer forensics, please pay attention!
