  • Patent number: 6266680
    Abstract: A method for electronically checking documents as to their authenticity is disclosed, in which an official seal is not put on the document, but the document itself shows to be notarized, and the authenticity of a document can be electronically confirmed. The method for electronically checking the authenticities of documents includes the step of forming a document with an electronically authenticity-checking format for showing that a document has been notarized without using an official seal (first step). It further includes the step of judging as to whether the document with the electronically authenticity-checking format has been really notarized (second step). Therefore, a notarization feature can be provided even to facsimile documents and to printed-out documents. Therefore, a document having a notarization feature can be transmitted even to a remote place, thereby preventing forgery of documents.
