摘要： In accordance with an embodiment of the invention, a method for creating a self-authenticating document is disclosed. The method comprises: providing a base substrate forming the document; printing an authentication seal on the document, the authentication seal comprising a printed portion comprising an ink creating a bleed area on the document where the ink and the substrate interact; and obtaining unique bleed properties of the bleed area. The bleed properties are obtained by scanning the bleed area upon termination of bleeding or drying to provide a description of the ink and substrate interaction to generate an identifier code representing the unique bleed properties. The method further comprises generating a signature of the identifier code, encoding the identifier code in an information carrier, and associating the information carrier with the document or storing the signed identifier code in a remote verification seal code that is not printed on the document. The authentication seal is capable of being scanned and compared to the information carrier or to the remote verification seal code, wherein the verification seal code is not located on the document and comprises the same code information as the identifier code.

摘要： A method for incorporating fraud detection features in a printed image. The method includes the steps of providing an impact printer having a plurality of impact pins for producing pixels on a substrate, developing an encoding scheme within the printed image, and controlling the impact printer to produce the pixels in accordance with the encoding scheme. More specifically, the encoding scheme is characterized by predefining a group of pixels within the printed image and determining the pixel density characteristics thereof, e.g., light or dark pixels. Furthermore, the impact printer is controlled to vary the magnetic flux density across each solenoid, thereby varying the impact pressure applied by the impact pins on the print ribbon. By selectively controlling the magnetic flux density at least some of the respective print densities of each of the respective printed pixels are different from each other to define an encoding scheme within the printed image. Variation in pixel density may be produced by changing the magnitude, pulse width or frequency of the voltage/pulse applied to the solenoids of the impact printer.

摘要： A system (126-129) detects transmission of potentially malicious packets. The system (126-129) receives packets and generates hash values corresponding to each of the packets. The system (126-129) may then compare the generated hash values to hash values corresponding to prior packets. The system (126-129) determines that one of the packets is a potentially malicious packet when the generated hash value corresponding to the one packet matches one of the hash values corresponding to one of the prior packets and the one prior packet was received within a predetermined amount of time of the one packet. The system (126-129) may also facilitate the tracing of the path taken by a potentially malicious packet. In this case, the system (126-129) may receive a message that identifies a potentially malicious packet, generate hash values from the potentially malicious packet, and determine whether one or more of the generated hash values match hash values corresponding to previously-received packets. The system (126-129) may then identify the potentially malicious packet as one of the previously-received packets when one or more of the generated hash values match the hash value corresponding to the one previously-received packet.

摘要： A system and method for identifying target packets in a network. The invention identifies packets by computing a hash value over at least a portion of a packet passing through a network device such as a router. The hash value is used as an address, or index, into a memory. The hash value identifies a unique memory address and a flag is set at the respective memory location. When a target packet is detected elsewhere in a network, the network device receives a query message containing a hash value of the target packet. The network device compares the target packet to the hash values in memory. A match between the hash value in memory and the hash value in the query message indicates the target packet was observed by the network device. After a match is detected, the network device makes a reply available to the network.

摘要： A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to either block bands of light corresponding to the light being emitted by either the first source or the other sources. By sequentially engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.

摘要： Methods and systems to monitor the operation of ink jet print heads that are easy to implement and inexpensive are provided. The print head is positioned over an array of wires. The array of wires is heated, and the print head is controlled to eject droplets of ink from each nozzle of the print head onto a corresponding wire. Nozzles that are operating properly will eject droplets of ink, which will lower the temperature of the wire, thereby causing a change in resistance of the wire. Nozzles that are not operating properly will not eject droplets of ink, and therefore the resistance of the corresponding wires will remain constant. The resistance of each wire is monitored, and if a change in resistance in a wire is not detected, indicating that the ink droplets were not ejected onto that wire, a signal is generated that indicates a non-operational nozzle.
