The Research And Implementation Of Multi-language System Based On Chinese, Japanese, And Korean

At present, the computer forensics put it's emphases on Simplified Chinese in windows. Along frequently international communication and embedded reform and open policies, the cases about foreigners are increasing continuously. Because of the lack of precise multiplicate language tool to deal with, the investigators have to spend much time on the disposal of computer data. At the same time, to use the different methods make the technics difficult to spread.For the questions above, this paper analysed the shortage of information analysis and computer forensics system, and researched the computer code regulations in China, Japan, and Korea. Through giving the hex code of possible key words for search, let the investigators use standard software for computer forensics to search the key words easily and fleetly. So, it can predigest the work of forensics, and improve the work efficiency under the premise of work quality.This paper described the significance of the multi-language system based on Chinese, Japanese, and Korean firstly, introduced the island and overseas status quo of computer forensics. Then, it traversed most kind of codes which the computers in China, Japan, and Korea refer to. Then, used Unicode as kerneled code, lucubrated to the local codes, such as GB2312, BIG5, GBK, etc. in Chinese, JIS, SHIFT_JIS, EUC-JP, etc. in Japanese, EUC-KR, etc. in Korean; the quadratic codes such as rtf document, base64 and QP code; and the Unicode. The system sustain to export a batch EnCase' scrips of key words search. Then the paper introduced the design of system, the environment to run, and basic circs to implement concretely. Finally, summarized the system development and on the lack propose the next step to make efforts.Through testings, the system discussed in paper can effectively improve the work efficiency, enlarge the range of forencis search, and provide a good tool for striking computer crimes. It also can correct unreadable codes, enhance the communication of international information. It has been generalized widely, and has high significance for society, and applied value.
