Recently, popularity of digital devices increases cyber-crimes and it is very important to secure evidence of crimes in the devices. In order to remove data completely in the device, anti-forensic techniques like a file wiping are generally used. Accordingly, digital forensic techniques are required to search those evidence in the devices. Since most of digital devices are equipped with a flash memory as a storage device currently, hard disk-based forensic techniques cannot be applied on that situation. Also, recent studies on flash-based data recovery focus just on recovering particular files under restricted conditions. In this paper, we suggests a new technique which can secure evidence of file wiping in a flash-equipped storage device. Through diverse experiments, we show that our technique is better than the previous ones in terms of gathering evidence of file wiping.
