A computer privacy lock, which is dubbed "Poly Digital Guard", has been successfully developed by a research institute of the PLA General Staff Headquarters in partnership with the related units, and has recently passed experts' appraisal and evaluation. Computers equipped with such "digital guard" can have computer information protected in many aspects, such as safety for logging on, auto screen-lock, protection of directory file, encrypt transmission, and password management, etc.
