    摘要: A method for producing a metered tape and an indicium on a meter tape comprising determining a location on the meter tape where the indicium is to be printed, generating the indicium with information related to the location incorporated therein, and printing the indicium on the meter tape at the location. A method of authenticating an indicium printed on a meter tape comprising retrieving information stored within the indicium, the information identifying a first location where the indicium is supposed to be positioned relative to the meter tape, detecting a spatial indicator identifying a second location where the indicium is actually positioned relative to the meter tape, and comparing the first location to the second location. Mail metering and authenticating systems for implementing the methods are also disclosed.

    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: An electronic voting system includes a vote security device (VSD), a user interface for presenting a ballot to a voter, and an audit trail printer operatively coupled to the VSD. The printer prints an audit trail ballot only in response to verifying encrypted and/or digitally signed messages received from the VSD that indicates the voter's ballot selections. The printer is structured to allow the voter to view but not access the audit trail ballot. The voter is able to accept or reject the audit trail ballot using the user interface. If the ballot is rejected, the VSD causes the printer to print a rejection indicator on the ballot, and if the voter accepts the ballot, the VSD causes the printer to print an acceptance indicator on the ballot. A digitally signed record of the voter's ballot selections is generated and stored.

    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.
