Abstract: A signature scheme is provided in which a message is divided in to a first portion which is hidden and is recovered during verification, and a second portion which is visible and is required as input to the verification algorithm. A first signature component is generated by encrypting the first portion alone. An intermediate component is formed by combining the first component and the visible portion and cryptographically hashing them. A second signature component is then formed using the intermediate component and the signature comprises the first and second components with the visible portion. A verification of the signature combines a first component derived only from the hidden portion of the message with the visible portion and produces a hash of the combination. The computed hash is used together with publicly available information to generate a bit string corresponding to the hidden portion.

Abstract: Methods and systems for providing confidentiality of communications sent via a network that is efficient, easy to implement, and does not require significant key management. The identity of each node of the routing path of a communication is encrypted utilizing an identity-based encryption scheme. This allows each node of the routing path to decrypt only those portions of the routing path necessary to send the communication to the next node. Thus, each node will only know the immediate previous node from which the communication came, and the next node to which the communication is to be sent. The remainder of the routing path of the communication, along with the original sender and intended recipient, remain confidential from any intermediate nodes in the routing path. Use of the identity-based encryption scheme removes the need for significant key management to maintain the encryption/decryption keys.

Abstract: Methods and systems for verification of indicia that do not require key management systems, and in which revocation of key pairs is easily performed without adding costs to the verification process are provided. Indicia are generated and authenticated utilizing an identity-based encryption (IBE) scheme. A key generating authority generates a private key for a PSD, distributes the private key securely to the PSD, and provides public information for use by a verification service when verifying cryptographic digital signatures generated with the private key. The corresponding public key is a string consisting of PSD information that is provided as part of the indicium. The verification service can verify the signature of each indicium by obtaining the public key string from the indicium, and utilizing the key generating authority's public information.

Abstract: A method and system for secure package delivery utilizing digital signatures is described.

The data is read and independently verified at the package destination.

Abstract: A closed loop postage metering system includes networked meters that provide mailers and/or recipients the capability to request additional or modified services during processing of a mail piece by a carrier. The networked meter allows the Post to charge the mailer, or even the recipient for these services or to provide them with a refund or credit. The services can include changing the processing of the mail piece. Further, the closed loop postage metering system enables more precise methods of paying for services when multiple carriers handle a mail piece. A special case of such multiple carriers handling is the handling of international mail.

Abstract: Methods and systems for authenticating senders and recipients in a carrier system and providing receipt of specified content by a recipient are provided. A one-time recipient identification code is generated that can be entered into the delivery agent's portable terminal. Data is protected against eavesdropping by encryption and by splitting cipher text and an encryption key into two parts that are not accessible to any single party except at the moment of the mail unit delivery.

Abstract: A method that enables the post to deliver letters, flats, post cards and packages (mail) addressed to a recipient's virtual post office box and then to be delivered directly to the recipient. The process enables individuals or entities to rent a virtual post office (VPO) box i.e., a box that does not physically exist, from the post office (“post”). Mail addressed to the virtual post office box would be captured by the post during the post's sortation process and rerouted to the specified address of the renter of the virtual post office box.

Abstract: An improved check sorting system capable of ordering cancelled checks for a plurality of accounts in a predetermined manner other than by account number is provided. Checks are ordered according to a priority value associated with the account number, and optionally check number, identified by each check. A database is utilized to store information indexed by institution and/or account number and optionally check number. The information includes a priority value. The check sorting system scans each check and reads the MICR code from each check. The institution and/or account number, and possibly check number, from each check are used as pointers to obtain the priority value for that check. The check is then sorted based on the priority value obtained from the database.

Abstract: A method in which the creation of identifier information is done by the recipient in a convenient fashion and communicated to the mailer. A recipient, such as a business or consumer who orders mail items of value, i.e., merchandise, documents, etc., from a mailer would give the mailer the recipient's electronic address and the recipient's delivery and handling preferences for the ordered merchandise. The electronic address and delivery and handling preferences of the recipient may be given to the mailer in plain language or in codified or encrypted form. This invention takes into account recipient's desires and preferences by entering information about the recipient's desires and preferences into a computerized actionable form.

Abstract: A mailing list is created including destination addresses for mailpieces to be submitted to a carrier service for delivery. A unique mailpiece identifier associated with mailpieces on the mailing list is generated by the carrier or other trusted third party. The unique mailpiece identifier is printed on the mailpiece with which it is associated. The mailpieces with the printed unique identifier are submitted to the carrier service. The carrier service obtains the printed unique identifier from the mailpiece. The obtained unique identifier from each said mailpiece is utilized to verify that data associated with the mailpiece has been processed by the carrier or trusted third party. When the unique number has been obtained from the mailpieces, the carrier service, if desired, may note this fact in the carrier records to prevent reuse of the unique identifier.

Abstract: The present invention uses an element of digital data that is created during digital postage mark (DPM) generation process from the digital image of the destination address block. The digital data is included into recoverable portion of the digital signature and imprinted on a mailpiece. During DPM verification, a representative portion of a destination address block image is retrieved in its original form from the digital signature itself. The retrieved portion of the image then can be compared with the similar digital data obtained from the scanned destination address block obtained during normal mail scanning and processing activities. If the comparison is under a predetermined threshold, then the DPM is declared authentic and the mailpiece can be processed and delivered with confidence. If, on the other hand, the threshold is not met, the DPM is declared a copy or a counterfeit of another DPM and the mailpiece can be subjected to further investigation.
