Secure system for creating and validating personal identification cards with operator discretion

A method of making and using a secure ID card in which ambiguous discrepancies are identified and presented to a human operator to allow a pass-fail decision to be made on the basis of informed human judgment, the method comprising the steps of:

• creating an ID card for a user which includes at least one unambiguous digital identifier, at least one graphical information field, and at least one text information data field in which each of said graphical information fields and text information data fields is assigned a predetermined limit of acceptable anomaly;
• scanning said ID card to create a composite digital image;
• transmitting said composite digital image over a data network to a data server;
• storing said composite digital image on a central database in association with said at least one unambiguous digital identifier;
• optically scanning and digitally encoding a presenter's ID card presented for authentication at a gatekeeper station attended by a human operator;
• transmitting said digitally encoded presenter's ID card to a comparison computer associated with said central database;
• comparing said digitally encoded presenter's ID card with the digital images stored in said central database;
• performing a first matching step using said comparison computer to match said presenter's ID card with an unambiguous digital identifier in said central database, and generating a first pass-fail result;
• if said first matching step generates a pass result, performing a second matching step using said comparison computer to compare said presenter's ID card with the composite digital image stored on said central database in association with said presenter's ID card in which said comparison computer compares the said at least one text information data field and at least one graphical information field of said presenter's ID card with the corresponding data stored in said central computer against its said predetermined limit of acceptable anomaly, generating a numerical error message, and including said numerical error message in said first and second pass-fail results with an indication of which information field failed to yield a match with the presenter's ID card;
• and
• transmitting said first and second pass-fail results, together with said indication of which information field failed to yield a match with the presenter's ID card, back to said gatekeeper station and human operator for the exercise of operator judgment in accepting said presenter's ID card, whereby said human operator is enabled to determine which field of the presenter's ID card has caused an anomaly, and to what degree.
