Abstract: Systems and methods for detecting copies of documents are described. In one example, a system and method for detecting copies of documents utilizes multiple authentication tests performed using original and scanned copy detection patterns. The system captures a CDP that may be skewed or improperly sized. The system also retrieves or reconstitutes the expected CDP. Then the system performs a first correlation to determine if the captured CDP indicates the correct document identification and then if necessary, one or more authentication tests are applied wherein the authentication test may be grouped into distinct orthogonal test groups. The authentication tests applied may be selected according to usefulness, system throughput or target document valuation parameters.

Abstract: A method for printing an original image which is protected against copying or alteration, such as a postal indicium, and for determining if that image has been altered. The image includes a copy detection feature and coded information linked to the copy detection feature. Altered images are detected by testing to determine if the link between the copy detection feature and the coded information in fact exists. The copy detection feature and the coded information can be linked by: 1) scanning the image to recover the coded information and the copy detection feature; 2) test the coded information and copy detection feature, and 3) accept the printed image as unaltered if the test indicates that the nominal link exists in fact.

Abstract: 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 within a predetermined band of wavelengths. To read the signature, light having wavelength within the predetermined band can be directed onto the window, thereby rendering the window transparent and the signature visible.

Abstract: Methods and systems for providing confidentiality of communications sent via a network that is efficient, easy to implement, and does not require significant key management. The identity of each node of the routing path of a communication is encrypted utilizing an identity-based encryption scheme. This allows each node of the routing path to decrypt only those portions of the routing path necessary to send the communication to the next node. Thus, each node will only know the immediate previous node from which the communication came, and the next node to which the communication is to be sent. The remainder of the routing path of the communication, along with the original sender and intended recipient, remain confidential from any intermediate nodes in the routing path. Use of the identity-based encryption scheme removes the need for significant key management to maintain the encryption/decryption keys.

Abstract: A method of conducting an election including storing a signature image for each voter, providing a plurality of return envelopes, providing an indicium having a barcode on each of the return envelopes, for each of the return envelopes, associating the barcode of the indicium with a respective one of the voters, and mailing each return envelope and a ballot to the voter with which the barcode data of the indicium of the envelope has been associated. When each return envelope including a completed ballot and a written signature thereon is received, the method includes obtaining from the return envelope the written signature and the barcode of the indicium provided thereon, using the obtained barcode to access the stored authorized signature image of the voter with which the barcode is associated, and comparing the obtained written signature to the authorized signature in the accessed image.

Abstract: A method for encoding a message including the steps of performing two-channel encoding of the message into a robust string and a fragile string; transmitting the robust string through a fragile channel; and transmitting the fragile string though a robust channel (FIG. 6). Before the step of performing two-channel encoding of the message into a robust string and a fragile string the number of characters in the message may be reduced to reduce the size of the encode message. The two channel encoding step includes the steps of creating the robust string by encoding the message using the codeword dictionary; and creating the fragile string by encoding the message using a compression algorithm. The robust string may be transmitted by embedding the robust string in an image. The fragile string may be transmitted by embedding the fragile string in a 2-D bar code.
