| Abstract: | With frequent occurrence of sensitive information leakage,the protection of object reuse becomes more and more important in process of information system clssified security protection.This paper introduces principle of hard disk data deleting and recovering,and analyzing in detail the current mainstream disk overwriting standard,for instance US DoD 5220.22-M and Gutmann so no,and designing the method of disk overwriting to meet the different grade information system on this basis. |
