Abstract
Provided are an index analysis apparatus and method, and an index search apparatus and method. The index analysis apparatus extracts indexes from digital data, which is included in a disk image of a virtual drive, by using pattern matching, and the index search apparatus receives the extracted indexes and searches the digital data, which includes the received indexes, using a keyword keyed in by a user. Accordingly, the accuracy of digital forensic analysis can be increased, and digital forensic search can be sped up.
Claims16
An index analysis apparatus comprising:
- a virtual drive generation unit generating a virtual drive for digital data collected as evidence;
- an index analysis unit extracting indexes from the digital data, which is included in a disk image of the generated virtual drive, by using pattern matching;
- and
- a database storing the digital data having the extracted indexes.
An index search apparatus comprising an index search unit receiving indexes, which are extracted using pattern matching from digital data included in a disk image of a virtual drive, and searching the digital data, which comprises the received indexes, using a is keyword keyed in by a user.
An index analysis method comprising:
- generating a virtual drive for digital data collected as evidence;
- extracting indexes from the digital data, which is included in a disk image of the generated virtual drive, by using pattern matching;
- and
- storing the digital data having the extracted indexes,
- wherein in the pattern matching, the digital data is compared with a preset pattern, and parts, which match the preset pattern, are searched for in the digital data.
An index search method comprising receiving indexes, which are extracted using pattern matching from digital data included in a disk image of a virtual drive, and searching the digital data, which comprises the received indexes, using a keyword keyed in by a user.
