Summary:A process for evidencing postage payment begins by obtaining a destination address for a mail item and encoding it as a string of characters from which a subset of the encoded string is selected, concatenated with plain text data and then encrypted. The encrypted portion is hashed along and a digital signature is computed as part of the digital postage mark. During verification, the mail item is scanned to obtain a digital image thereof, which is parsed to identify and capture the digital postage mark and the destination address block. A recoverable portion of the DAB is extracted and the digital postage mark is parsed into a plain text area and a cryptographic validation code area. The CVC area is parsed to obtain a recoverable portion. If the recoverable portion of the DAB is within a threshold value of the recoverable portion of the CVC, then the mail item is accepted.
