    摘要: Print quality is ensured in a postage meter system employing an ink system and having settable modes of printing operation by detecting the type of ink system employed in the postage meter system, setting a first mode of printing operation for the postage meter system when the detected ink system is of a first type and setting a second mode of printing operation for the postage meter system when the detected ink system is of a second type. The detected information may be communicated to a data center to obtain modes of operation for the postage meter system and other corrective actions may be implemented. The method and system are applicable to other consumable item systems employing various types of consumable items.

    摘要: A method and apparatus for embedding information in an image during relative movement between a print medium and an ink jet print head is provided. A plurality of first lines are printed and a plurality of second lines are printed. Each of the first lines includes a plurality of first dots and a plurality of second dots offset from the first dots by a first amount, and each of the second lines includes a plurality of third dots and a plurality of fourth dots offset from the third dots by a second amount different than the first amount. The information is encoded in the image using an encoding scheme in which the first lines represent a first value in the encoding scheme and the second lines represent a second value in the encoding scheme.

    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: 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.
