Robus digital token generation and verification system accommodating token verification where addressee information cannot be recreated automated mail processing

A method for verifying postage evidencing information printed on a mail piece, comprising the steps of:

• obtaining an error correction code printed on a mail piece;
• determining that the obtained error correction code is inaccurate;
• obtaining the information employed to generate said inaccurate error correction code;
• generating an error correction code from said obtained information;
• and,
• employing said generated error correction code to verify the validity of said postage evidencing information.

A method for verifying postage evidencing information printed on a mail piece, comprising the steps of:

• obtaining an error correction code printed on a mail piece for other information printed on a mail piece;
• determining that the obtained error correction code is inaccurate;
• obtaining said other information employed to generate said printed error correction code;
• attempting to regenerate said error correction code from said obtained other information;
• determining that the obtained other information is inaccurate;
• employing said obtained error correction code and said obtained other information to regenerated a correct error correction code for said other information;
• and,
• employing said regenerated correct error correction code to verify the validity of said postage evidencing information.

A method for verifying postage evidencing information printed on a mail piece, comprising the steps of:

• obtaining an error correction code printed on a mail piece for other information printed on a mail piece;
• determining that the obtained error correction code is inaccurate;
• obtaining said other information employed to generate said printed error correction code;
• regenerating said error correction code from said obtained other information;
• and,
• employing said regenerated correct error code to verify the validity of said postage evidencing information.

A method for generating postage evidencing information comprising the steps of:

• generating an error correction code for at least a portion of destination address;
• generating address structure information for said destination address;
• imprinting said error correction code and address structure information on said mail piece;
• and,
• generating a digital token employing said error correction code and said address structure information.

A method for generating authentication and integrity information comprising the steps of:

• generating an error correction code for information printed on a document;
• generating document structure information for said information printed on said document;
• imprinting said error correction code and document structure information on said document;
• and,
• generating a digital token employing said error correction code and said address structure information.

A method for verifying postage evidencing information comprising the steps of:

• generating a first error correction code for at least a portion of a destination address of a mail piece;
• generating a first digital token including said first error correction code;
• including the first digital token in a postal indicia on the mail piece scanning said mail piece at a mail piece processing location for information from the mail piece;
• generating a second error correction code from the information;
• computing a second digital token using said second error correction code;
• determining mail piece validity by comparing said first digital token and said second digital token.

A method for verifying postage evidencing information comprising the steps of:

• generating an error correction code for at least a portion of a mail piece destination address;
• generating a first digital token including said error correction code;
• scanning said mail piece at a mail piece processing location to obtain mail piece information;
• obtaining said error correction code from said mail piece information and said destination address;
• determining whether said obtained error correction code corresponds to said obtained destination address;
• a) generating a second digital token using said obtained error correction code when said obtained error correction code corresponds to said obtained destination address;
• b) determining mail piece validity based upon a comparison of first and second digital tokens;
• or,
• c) regenerating said error correction code when said obtained error correction code does not correspond with said obtained destination address;
• d) generating the second digital token using said regenerated error correction code;
• and
• e) determining mail piece validity based upon said computed digital token and said regenerated digital token.
