Abstract: In a method for recovering a partition using backup boot record information, an unallocated area is separated from a disk or an evidence image. The unallocated area is searched for a location of a backup boot record. Whether is backup boot record of a file system to be detected is present in found sectors is analyzed. If the backup boot record is found to be the backup boot record of the file system desired to be detected as a result of the analysis, it is verified whether the backup boot record is a boot record of a valid partition. If it is verified that the backup boot record is the boot record of the valid partition, a file system of a deleted partition is parsed using the backup boot record and a deleted directory or file is recovered.

Abstract: Disclosed herein are a data protection apparatus and method for a smart device. The data protection apparatus for a smart device includes a detection unit for detecting unauthorized activity in a bootloader of the smart device, based on whether a program for acquiring an administrator privilege has been installed and whether a compressed-command file is present, during a procedure for loading the bootloader, and a data access blocking unit for, when the unauthorized activity is detected, performing an operation of locking the smart device, thus blocking access to data in the smart device.
