摘要:
A proof-of-postage generating system (22, 24, 25, 26, 27) wherein funds, application of those funds, the replenishment of those funds and the auditing of those funds are secure against attempts at fraud. The system (22, 24, 25, 26, 27) may either be a Closed System (CS) wherein the proof-of-postage printing means (22) are housed within the system computational means (24, 26) or within a cryptographically secure boundary. Further, the system (22, 24, 25, 26, 27) may be an Open System (OS) wherein the proof-of-postage printing means are external to the system computational means (24, 26).
摘要:
In a mailing system for franking a postage indicium serving as a proof of postage, postal data including the postage needs to be communicated through such an indicium. Illustratively, the postal data is categorized into (a) invariable postal data, e.g., a device ID identifying the mailing system, which is unaffected by a franking transaction, and (b) variable postal data, e.g., the postage, which may change from one franking transaction to another. To avoid latency of the franking operation, the invariable postal data is preset for initial printing of the postage indicium, and the variable postal data is determined and set for printing in real time. In printing the postage indicium, the invariable postal data and the variable postal data are presented in that order in one or more symbols.
