Abstract

Flash memory based Solid State Drives(SSDs) become an indispensable part in mobile computers. To protect confidential data from being leaked, user have to run secure deletion software to erase the confidential files. However the traditional secure deletion software may report success on SSDs, but do not work at all. To solve the problem, we proposed a per-file secure deletion method to clean up the sensitive data without erase the whole SSD. In addition, RAID technique is also employed to enhance the reliability and eliminate the potential risk caused by secure deletion.
