Abstract
A method for generating evidencing information for a document includes generating an error correction code and generating a digital token employing the error correction code. A method for verifying authentication and integrity information printed on a mail piece includes obtaining an error correction code printed on the document and employing the obtained error correction code to verify the validity of the evidencing information. A method for verifying the evidencing information printed on a mail piece includes obtaining an error correction code printed on a mail piece and determining that the obtained error correction code is inaccurate. The information employed to generate the inaccurate error correction code is obtained and an error correction code is generated from the obtained information. The generated error correction code is employed to verify the validity of the evidencing information. The document may be a mail piece and the evidencing information postage evidencing information with the error correction code being for at least a portion of destination address information.
