No, you cant the comparison does not necessarily work on the same data (as in binary same), but rather on some level of similarity. you would need to teach your database to recognize which prints are similar to the one you just got, which is actually all that fprint does Pavel _______________________________________________ fprint mailing list fprint@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/fprint
