| Abstract: | A technology of location the illegal manipulation to Microsoft Word documents is addressed and the corresponding system prototype is designed. This system can be combined with existing backup server and reduce greatly the time consumed on backup and updating. The result of simulation reveals that this system can not only detect the illegal manipulation but also locate them in definite range. |
