Abstract

In a franking method and a mail transport system, a franking image is calculated before generation thereof on a mail piece. The franking image includes a franking image key, and for each new franking image, the franking image key therefor is derived from a predecessor franking image key according to a first crypto-algorithm. An integrity check code is also generated based on the new franking image key, a key generation number, an apparatus identifier of the franking device, and a second crypto-algorithm. The franking image includes at least the device identifier, the key generation number and the integrity check code. Upon transport of the mail piece to a sorting center, the franking image is scanned and fees for billing are generated based thereon.
