Abstract
This present invention describes an innovative solution in the area of indexing and searching binary files including various binary files such as multimedia files, including image files, mp3 files and other audio/video files from the public Internet. The invention introduces a way to index binary files such as multimedia files according to their content signatures, which uniquely identify themselves, and search for related files by walking through a graph database constructed during the index phase. The present invention can be used in a search engine and a download engine, as well as with text based index and search technologies. As a result, such extended usage will broaden a multimedia file's context and increase relevant accuracy of the keywords describing the context.
