  • Patent number: 8444181
    Abstract: A verifiable/copy-protected document features a combination of nearly identical line-screen patterns for embedding latent images within visually integrated settings. The latent images can be detected for purposes of verification with a matching viewer but are indistinguishable from their visually integrated settings under ordinary viewing conditions. The line-screen patterns, which can be incorporated into document artwork, are printed at certain combinations of line frequencies and print densities so that the line-screen patterns digitally reproduce as a largely undifferentiated solid tint.

  • Patent number: 8438397
    Abstract: A technique to ensure watermarking a highest selected layer for decoding when receiving a scalable coded bitstream having a plurality of bitstream layers. In one technique, the watermark is associated only with the highest layer that is selected from the hierarchically arranged layers and not in any of the lower layers of the hierarchy. In another technique, the watermarks are present in all the layers, but each lower layer watermark is compensated in a next higher layer to remove effects of the presence of the lower layer watermark in the next higher layer.

  • Patent number: 8321350
    Abstract: We provide techniques for uniquely linking security elements in identification documents. In one implementation we provide a digital watermark 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.
