    摘要: A method of printing a document includes generating commands in a computing device that include: (i) commands for printing based on document data, and (ii) an identification of a determined portion of the document data that is to be used in generating a printed copy detection pattern. The method further includes sending the printer control commands to an intermediate electronic device that stores a key, generating copy detection pattern data using the determined portion of the document data and the cryptographic key, and generating modified printer control commands that include commands for printing a first document portion based on the document data and a second document portion including the printed copy detection pattern based on the copy detection pattern data. Finally, the modified printer control commands are sent to a printing device. Also, a system is provided for implementing the method.

    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 for printing secure source images of the type that contain specific critical elements and non-secure images on a single printer includes determining the origin of an image (secure source or non-secure source). If the image to be printed is from the non-secure source, a determination is made if the image contains the specific critical elements of the type contained in secure source images. Printing of the image from the non-secure source is disabled if the image contains specific critical elements of the type contained in secure source images. Printing of the image from a non-secure source is enabled if the image does not contain specific critical elements of the type contained in the secure image. The determination if the non-secure source image contains the specific critical elements of the type contained in secure source images can be made after printing has commenced of the non-secure image.

    摘要: Methods and systems that provide privacy of signatures on envelopes containing ballots are provided. The envelope for returning ballots includes a flap with a window that aligns with a signature area on the envelope. The window appears opaque under normal lighting conditions, but appears transparent when illuminated with light having a predetermined wavelength. A movable signature stub is positioned on top of the signature area. The voter signs the back of the envelope on the signature stub, thereby imprinting a signature on the signature area by transferring a material from the signature stub to the signature area, and moves the signature stub. The flap of the envelope is then sealed, thereby covering the voter's signature in the signature area with the window of the envelope flap. To read the signature, light having the predetermined wavelength can be directed onto the window, thereby rendering the window transparent and the signature visible.

    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: A printing system for printing both secure value documents and non-secure documents while ensuring that fraudulent copies of secure value documents printed by the printing system can be detected is provided. The printing system determines if the source is a secure or non-secure source. If the source of the image is a secure source, it will print the image, including any graphic security features. If the source is a non-secure source, before printing the image a filter is applied to the image data to remove any graphic security features included in the received image and/or the printing system will not add any graphic security features to the received image to ensure that the printed image will not contain any copy detection graphic security features.
