<p>A method for generating postage evidence includes providing addressee information separated into a plurality of address fields. A predetermined section of each address field, appropriate for authentication purposes, is selected to obtain selected address data. An error correction code is generated for the selected address data and a secure hash is generated of the selected address data. The secure hash is sent with postal data, including postage amount and date, to a digital token generation process that generates at least one digital token using the secure hash for evidencing postage. An indicia including the digital token and the postal data is generated and then printed on a mail piece with the error correction code and the addressee information. In a digital token verification process, the addressee information and the error correcting code are read from the mailpiece and the postal data is read from the indicia. An error correction algorithm is used to determine if errors are correctable. If correctable, a predetermined section of each address field is selected to obtain selected address data. A secure hash of the selected address data is generated and sent with the postal data to a digital token verification process.</p> |
