VIRTUAL POSTAGE METER WITH SECURE DIGITAL SIGNATURE DEVICE

摘要

A method for controlling a postage metering system (1) defines a first set of postage parameters P1, P2, P3 to Pn associated with the generation of postage evidence in a postage metering system (10) and then initializes the postage metering system (10) with a subset of the first set of postage parameters F1, F2, F3 to Fn. The subset F1, F2, F3 to Fn defines a combination of the postage parameters for which the generation of postage evidence is not authorized. When a request for postage evidence is received, the request includes a second set of postage parameters P1, P2, P3 to Pn that are combined to form a postage parameter vector (PPV). The generation of postage evidence is inhibited when at least one of the postage parameters P1, P2, P3 to Pn in the second set matches one of the postage parameters in the first set F1, F2, F3 to Fn. When none of the postage parameters P1, P2, P3 to Pn in the second set matches one of the postage parameters in the first set F1, F2, F3 to Fn the requested postage evidence is generated. In an alternative method the subset defines a combination of the postage parameters for which the generation of postage evidence is authorized, and the requested postage evidence is generated when each of the postage parameters in the first set matches one of the postage parameters in the second set.
