Method of inhibiting token generation in an open metering system

摘要

A method is provided for inhibiting the generation of digital tokens in an open metering system that includes a host processor and a vault. The method includes the steps of generating in the host processor a first digital token request that corresponds to a first destination identifier and a first postage amount; determining in the host processor if one of the first destination identifier and the first postage amount is different than a prior destination identifier and a prior postage mount, respectively, that correspond to an immediately preceding digital token request; sending the first digital token request to the vault when the first destination identifier and the first postage amount are different than the prior destination identifier and the prior postage amount, respectively; and rejecting the first digital token request when the first destination identifier and the first postage amount are the same as the prior destination identifier and the prior postage amount, respectively. The method includes the further steps of notifying a user when the first destination identifier and the first postage amount are the same as the prior destination identifier and the prior postage amount; providing the user with a capability to confirm that the first digital token request is valid; and sending the first digital token request to the vault when the user confirms that the first digital token request is valid.
