ABSTRACT:
The present invention provides tools and techniques for distinguishing a file from any or all copies of the file that may exist. One method ascertains (204) the actual physical location of the file (512) and associates (214) that physical location with the file as the claimed physical location (516) of the file. The file's originality status may then be determined (104) by finding (304) the location claim, reading (306) from it the claimed physical location associated with the file, ascertaining (308) the actual physical location of the file, and comparing (310) the locations. If the claimed and actual locations are identical, then the file is the original file it claims to be. If there is disparity between the claimed physical location recited for or by the file and the actual physical location of the file, then it is not the original file it claims to be.
