Abstract :
Flash memories find wide use in storing data in any application. Data deletion in flash memories involves making the data unreliable on the device. As contents get deleted in the flash memory, time is consumed in deleting the data on the flash permanently. This paper proposes a method to make the contents of the deleted blocks in the flash memory unreliable. The proposed method can be used for any algorithm used for data security in terms of error detection and correction. The method involves introducing appropriate number of errors in the data and control bits of the blocks of data making data recovery impossible.
