ABSTRACT:
A system and method for authenticating records. Certification information may be encoded in graphical form. This graphical form, or design, may be referred to as an “Indicia.” The record at issue may be printed out by a computer or stored electronically and bear on it an indicia that relates to the authenticity of the document. The indicia (and record) may then be scanned and interpreted by the computer to authenticate the record.
