An apparatus for evidencing an occurrence of a transaction is provided that includes a tamper indicating housing, a processing unit provided within the tamper indicating housing, and a cryptographic module also provided within the tamper indicating housing. The processing unit is adapted to: (i) determine current location information indicating a current location of the apparatus, (ii) obtain transaction information relating to the transaction, and (iii) compile a data block including at least the current location information and the transaction information. The cryptographic module is adapted to generate cryptographic evidence based on the data block. The processing unit may also be adapted to obtain current time information, and the data block may further include the current time information. The processing unit may also be adapted to obtain user authentication information, such as biometric information, and the data block may further include the user authentication information.

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.

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.

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.

A method includes scanning a page of a paper document to generate a first digital page image. The method further includes obtaining a second digital page image which corresponds to a second page. The method also includes comparing the first digital page image pixel-by-pixel with the second digital page image to generate a score that indicates a degree to which the first digital page image differs from the second digital page image.
