摘要：
A system (10) and method of evidencing postage payment includes a data center (3) with a database (36) having a plurality of meter records (64) stored therein. Each meter record (64) includes meter information corresponding to a metering account assigned to each of a plurality of remote user devices (20, 22) that are authorized to request evidence of postage payment. When a request for postage (100) is received at the data center (30), a secure co-processor device (44) in the data center (3) obtains the appropriate meter record (64) and verifies the authenticity of the meter record (64) by verifying a signature (205, 210) in the meter record (64) and comparing freshness data (220, 225) in the meter record (64) to freshness data in the secure device (44). If verified, the secure device (44) then accounts for an amount of postage to be evidenced (130), generates evidence of postage payment (130) and updates the meter information, including the freshness data (130), in the meter record (64). The secure device (44) then signs the updated meter information and stores the signature in the meter record (64, 135, 140). The secure device (44) then returns the updated meter record (64) to the database (36, 135, 140).
