Recently, flash memory is used as storage system of digital devices. Anti-forensic techniques like file wiping is being tried to completely delete the stored files on flash memory, since they are clues in a criminal investigation. Therefore, it is necessary to develop digital forensic techniques for the analysis of digital evidence on flash memory to win anti-forensic techniques. Recently, data recovery approaches on flash memory have been proposed, which are heavily dependent of metadata stored on flash memory. This paper suggests a new technique to be able to recover data on flash memory deleted by file wiping. Differently from the previous techniques, our scheme can recovery deleted files without metadata on flash memory. Through diverse experiments, we show that our approach is a higher level of the data recovery technique compared with the existing techniques.
