A method and system for dispensing and evidencing indicia by an indicia
generating device is disclosed in a system having a plurality of indicia
generating devices that have been divided into n groups. Each of the
indicia generating devices generates and prints indicia on a media that
is to be received at a plurality of establishments, wherein the
establishments are associated with different geographic designations. The
method and system include receiving a plurality of verification keys,
wherein each one of the received verification keys is encrypted as a
function of a respective geographic designation. A plurality of key IDs
are also received, where each one of the key IDs is associated with one
of the verification keys and is encrypted as a function of the same
geographic designation used to encrypt the corresponding verification
key. In response to receiving a request to generate an indicium for a
media destined for a particular one of the establishments, the indicia
generating device evidences the indicium by generating one of the
verification keys and the corresponding key ID assigned to indicia
generating device's group based on the geographic designation associated
with the particular establishment, and using the generated verification
key to create a digital signature, and digitally signing the indicia by
including the digital signature and the generated key ID in the indicia.
