    摘要: Systems and methods are disclosed for providing security to an identification document having at least one storage element capable of storing information. An encryption key is provided, the encryption key comprising a public key and a private key. An optically variable device (OVD) in a machine readable format is created, the OVD associated with the public key. A payload of data is generated for storage in the storage element. At least a portion of the payload of data is encrypted with the private key, and the encrypted payload of data is transmitted to at least one location on the identification document. At least a portion of the data payload can be based on data that is randomly selected from data stored in the storage element or that is encrypted from data that is stored in the storage element. The storage element can comprise an optically variable device (OVD), optical storage media, hologram, KINEGRAM, Exelgram, Pixelgram, three dimensional bar code, a two dimensional bar code, a magnetic stripe, and a chip. Transmitting the encrypted payload can comprise at least one of embedding, digitally watermarking, printing, and encoding encrypted data in at least one location on the identification document.

    摘要: We provide techniques for uniquely linking security elements in identification documents. In one implementation we provide a digital watermark embedded embedded on, and a smartcard chip embedded in, an identification document. The smart card chip includes a hash or a reduced-bit representation of the digital watermark, while the digital watermark includes a hash of information stored on the smartcard chip. In another implementation we cross-correlate encryption keys carried by various machine-readable features on an identification document. In still another implementation, we embed biometric information, which is stored in smartcard electronic circuitry, with a digital watermark. In one case the watermark is reversible, so that it can be removed to yield unmarked biometric information. In another case the watermark is fragile, to reveal whether the biometric information has been subjected to a transformation. In yet another implementation, we provide a jurisdictional indicator on an identification document. The jurisdictional indicator helps in decoding a digital watermark on the identification document.

    摘要: One aspect of the invention comprises a method of embedding data in a code readable by machine from a visible light scan of the code. The method comprises pre-printing a two dimensional array of pixels on a substrate. The pixels include at least one calibration pixel, and each have color values. The method selectively alters at least a subset of the pixels by using laser radiation to alter color saturation of the color values of the pixels in the subset relative to the calibration pixel according to digital data values of the code to be embedded in the subset of pixels. This method has been adapted to embed personalized information in pre-printed graphic elements on ID cards.

    摘要: A capture station for creating identification documents comprises a housing including a camera and lighting device, a base, and at least one leg extending from the base. The housing is mounted to the leg to enable height adjustment of the camera. One configuration of the capture station has two substantially rigid and parallel legs with the housing mounted between the legs. Configurations of the capture station can include a processor, such a CPU or embedded controller, enabling ID document data capture functions to be executed within the capture station, and to be controlled via a remote computer via a network connection. In one embodiment, the processor is housed in the base and communicates with the camera via wiring routed through the leg. Peripherals used in capture functions, such as a fingerprint reader, signature pad, display, etc., may be mounted to the leg via clamps, or a plug in receptacle with power and communication wiring provided in the leg.

    摘要: A method for issuing a credential includes scanning in documents (e.g., breeder or ID documents) used to verify the applicant of the credential and creating data records including the image of the documents. As a means to reduce fraud, these data records are linked to the credential and to the issuer location, operator and time and place of issuance. If the document includes machine readable information, the method automatically reads the machine readable information from the document and uses at least part of the machine readable information from the document to pre-populate a form used to create a credential, such as an identification document. The method includes applying a transformation to the image of the document that enables protection against fraudulent use. The transformation secures the image of the document from tampering and/or enables tracking of the use of the document image to deter fraud. A method of verifying a credential comprises reading a physical security feature attribute on the credential, reading a logical attribute on the credential, and comparing information from the physical security feature with the logical storage element on the credential to verify the credential.

    摘要: An all in one capture station for creating photo identification documents combines the functions of a camera assembly and computer workstation into a single device. This device can be operated in a shared mode where it is controlled via one or more other workstations, or a stand alone mode, where it performs all of the functions needed to prepare an identification document. The all in one capture station includes a camera stand, a camera mounted within the camera stand, and a computer integrated into the camera stand. The computer includes a processor, network interface device, and memory. The memory stores a camera control program and a network interface program for transferring camera control commands and image data between the capture station and a remote workstation so that the capture station can operate under the control of the remote workstation to capture data for incorporation into an identification document.
