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.

Tools

libmagic

  • 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.
  • http://sourceforge.net/projects/libmagic

Bibliography

2001

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!
