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 makes data unreliable by swapping most significant bits into least significant bits in block of data making data recovery impossible
