摘要:
A method for ensuring for each postage transaction in a postage meter having a vault subsystem (3) and a printing subsystem (5) that debiting occurs prior to printing of a postal indicia includes authenticating the postage transaction as being valid, performing debiting within the vault subsystem (3), sending an encrypted debit certificate from the vault subsystem (3) to the printing subsystem (5), independently recreating the encrypted debit certificate in the printing subsystem (5), comparing the encrypted debit certificate with the recreated encrypted debit certificate to ascertain if a predetermined relationship exists therebetween, and initiating printing of the postal indicia only upon determination of the existence of the predetermined relationship. An apparatus incorporates the method.
摘要:
A public key cryptographic system is disclosed with enhanced digital signature certification which authenticates the identity of the public key holder. A hierarchy of nested certifications and signatures are employed which indicate the authority and responsibility levels of the individual whose signature is being certified. The certifier in constructing a certificate generates a special message that includes fields identifying the public key which is being certified, and the name of the certifee. The certificate is constructed by the certifier to define the authority which is being granted and which may relate to wide range of authorizations, delegation responsibilities or restrictions given to, or placed on the certifee. Methodology is also disclosed by which multiple objects such as, for example, a cover letter, an associated enclosed letter, an associated graphics files, etc, are signed together. Methodology is also disclosed for digitally signing documents in which a digital signature is generated for both computer verification and for reverification if a document needs to be reconfirmed by reentering from a paper rendition.
摘要:
A public key cryptographic system is disclosed with enhanced digital signature certification which authenticates the identity of the public key holder. A hierarchy of nested certifications and signatures are employed which indicate the authority and responsibility levels of the individual whose signature is being certified. The present invention enhances the capabilities of public key cryptography so that it may be employed in a wider variety of business transactions, even those where two parties may be virtually unknown to each other. Counter-signature and joint-signature requirements are referenced in each digital certification to permit business transactions to take place electronically, which heretofore often only would take place after at least one party physically winds his way through a corporate bureaucracy. The certifier in constructing a certificate generates a special message that includes fields identifying the public key which is being certified, and the name of the certifiee. In addition, the certificate constructed by the certifier includes the authority which is being granted including information which reflects issues of concern to the certifier such as, for example, the monetary limit for the certifiee and the level of trust which is granted to the certifiee. The certificate may also specify cosignature requirements which are being imposed upon the certifiee.

A method of manufacturing a postage printing device that is to be registered by a registering entity having a public/private key pair. The manufacturing station has a manufacturing station public/private key pair. The method includes storing a root certificate comprising the registering entity public key signed by the registering entity private key in the postage printing device, generating a transport public/private key pair, and storing the transport private key in the postage printing device. The method also includes generating a transport certificate comprising the transport public key signed by the manufacturing station private key, and storing the transport certificate in the postage printing device, after which the postage printing device is set to a transport lock state so that it can be securely transported. Also, a method of registering a postage printing device manufactured in this manner prior to operation of the postage printing device.

An apparatus and method for creating negotiable items includes, in a system including a network of a governing authority and at least one remote printer, a secure indicia authorized by the governing authority. A preprinted form, authorized by the governing authority, transformable into a negotiable item upon the application of the secure indicia at the remote printer is provided. Further, a database, controlled by the governing authority, for issuing the secure indicia and the preprinted form and accounting for the use of each at the at least one remote printer oversees the creation of the negotiable item.

A system includes an accounting register; structure for creating and attaching a digital signature to a message; a memory having stored therein a plurality of different indemnification provisions and a plurality of different service rates each associated with a corresponding one of the plurality of different indemnification provisions; apparatus for selecting and associating a specific one of the plurality of different indemnification provisions to the digital signature; and a device for adjusting the accounting register, wherein at times when the specific one of the plurality of different indemnification provisions has been selected and associated with the digital signature the adjusting device accounts for a one of the plurality of different service rates that corresponds to the specific one of the plurality of different indemnification provisions.
摘要:
A method is provided for determining origin ZIP code for a postage meter. The method includes receiving at a data center a call that originates from the location of the postage meter. Using caller ID, the data center determines the phone number originating the call. The data center also determines the identification of the postage meter. If the phone number has changed from a phone number from the previous phone call for the postage meter, the data center obtains a five-digit ZIP code for the address corresponding to the phone number. If the five-digit ZIP code has changed from a previous ZIP code used for postal accounting during previous transactions for the postage meter, the data center obtains a new certificate based on the five-digit ZIP code and downloads the new certificate to the postage meter. The data center transfers postage meter register values to a new postal account for the new certificate.
