File Format Identification is the process of figuring out the format of a sequence of bytes. Operating systems typically do this by file extension or by embedded MIME information. Forensic applications need to identify file types by content.
- Written in C.
- Rules in /usr/share/file/magic and compiled at runtime.
- Powers the Unix “file” command, but you can also call the library directly from a C program.
- Writen in Java
- Developed by National Archives of the United Kingdom.
- XML config file
- Closed source; free for non-commercial use
Forensic Innovations File Investigator TOOLS
- Proprietary, but free trial available.
- Available as consumer applications and OEM API.
- Identifies 3,000+ file types, using multiple methods to maintain high accuracy.
- Extracts metadata for many of the supported file types.
- Proprietary but free demo.
- Provides detection of password protected archives, some files of cryptographic programs, Pinch/Zeus binary reports, etc.
Current research papers on the file format identification problem. Most of these papers concern themselves with identifying file format of a few file sectors, rather than an entire file. Please note that this bibliography is in chronological order!
