Abstract: A method and system for creating, reviewing and revoking, if necessary, a certificate for a client of a service provider of a communications network, wherein the client has a client private key and a client public key. The method includes the steps of establishing a communications link with the service provider through a dedicated communication channel; requesting a client certificate from the service provider; obtaining a caller-ID, including a telephone number from an operator of the dedicated communication channel; and creating the requested client certificate including the caller-ID. Preferably, the method also includes the step of verifying that the caller-ID obtained from the operator of the dedicated communication channel is the same as client identifying information provided by the client when requesting the client certificate. The certificate can be stored at a caller ID server or a client's storage.

Abstract: A postage metering capability is integrated in an automated teller machine. With minimal modification and using several components of the ATM to perform functions useful in dispensing of postage, the secured environment of an ATM is used to implement numerous postage metering functions. When used with a smart card, postage value is accounted for without reference to an internal vault of the apparatus or to a postal facility, by using a vault of the smart card. The smart card may be used to dispense postage by accessing a customer's postage account at a remote center to set into the internal vault a value to be dispensed, with communication secured in accordance with information provided by the smart card. Using such information, the customer's postage account may also be accessed to recharge the vault of the smart card, rather than the internal vault. Additionally, postage may be dispensed in accordance with value inputted directly by a customer, using cash, credit-, debit-, or money-cards.
