    摘要： In accordance with an embodiment of the invention, a method for creating a self-authenticating document is disclosed. The method comprises: providing a base substrate forming the document; printing an authentication seal on the document, the authentication seal comprising a printed portion comprising an ink creating a bleed area on the document where the ink and the substrate interact; and obtaining unique bleed properties of the bleed area. The bleed properties are obtained by scanning the bleed area upon termination of bleeding or drying to provide a description of the ink and substrate interaction to generate an identifier code representing the unique bleed properties. The method further comprises generating a signature of the identifier code, encoding the identifier code in an information carrier, and associating the information carrier with the document or storing the signed identifier code in a remote verification seal code that is not printed on the document. The authentication seal is capable of being scanned and compared to the information carrier or to the remote verification seal code, wherein the verification seal code is not located on the document and comprises the same code information as the identifier code.

    摘要： 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.

    摘要： A method and system for securing the communication link between the accounting device and printer of a metering system by authenticating the data being sent via the link utilizing a Nonlinear Feedback Shift Register (NLFSR) based system is provided. A NLFSR is provided in each of the accounting unit and printing unit of a metering system. The NLFSR in the accounting unit is utilized to generate a message authentication code (MAC) for the image data being sent from the accounting unit to the printing unit. The printing unit generates a corresponding MAC for the received image data using the NLFSR in the printing unit. The MAC generated by the printing unit is compared with the MAC generated by the accounting unit. If the MACs are similar, the image data is accepted as authentic and the printing unit will print the image corresponding to the image data.

    摘要： An opt-in email system in which a recipient that has opted in to an email list can recognize and trust that an email has actually come from a desired sender. When a recipient desires to opt-in to an e-mail list, the recipient is sent to a trusted third party certification service that generates a certificate associated with a key pair. A key is maintained at the sender's location by a secure cryptographic device that can verify the certificate and create a signature, using a key of the key pair, for messages intended for the recipient. When a message intended for the recipient is received from the sender, the signature will be verified based on the status of the certificate and the corresponding key of the key pair. If the signature does not verify, it indicates that the recipient has not opted-in to receive emails from this sender.

    摘要： A method of printing an image having a graphic security element included therein includes receiving main image data representing a main image, receiving graphic security element data representing a graphic security element to be included in the main image, receiving a request to print the main image, responsive to receiving the request to print the main image, determining particular pixels of the main image data that are to be shifted based on the graphic security element data, and causing a plurality of ink deposits to be deposited on the print medium based on the main image data including causing the position of each of the ink deposits on the print medium that is determined to correspond to shifted pixels to be shifted relative to a normal position that would normally result from the main image data. Also, system that implements the method is provided.
