A system and method of monitoring font usage is provided whereby fonts are monitored on a distributed computer network such as the Internet by searching for a font represented by a font image or font file, extracting metadata from said font image or font file to populate a font database, and using information extraction means and comparison means with information on the font database to detect and record whether usage of the font has been authorized according to the license of the copyright owner. Preferably, said comparison means are implemented by generating an image preview of an unknown font file and comparing the hash of the resulting image with hashes of images of known font files. Reports may be generated which rank infringing websites according to predetermined criteria including estimated number of downloads of restricted font files and financial status of the website owner. |
