Abstract: A digital watermarking system and method are disclosed. In one respect, the disclosed digital watermarking includes generating an extracted signal by applying a watermark extractor to an original image, generating a mixed signal by mixing the first signal with a periodic watermark signal using a local weighting factor for the periodic watermark signal that attenuates a strength of the watermark signal in proportion to a pixel luminance level, and replacing the extracted signal in the original image with the mixed signal to generate a marked image, wherein the watermark signal is extractable from the marked image using the watermark extractor.

Abstract: Methods, systems and devices for securely transferring digital data from a first repository to a second repository are disclosed. Per at least one embodiment, a second repository is identified with a human recognizable identifier and an internal identifier associated with such second repository is determined. When a data transfer is desired, a work order associating the data to be transferred and identifying the second repository based on each of the human identifier and the internal identifier is generated. Such work order is utilized by a data port device to open normally closed communications port to accomplish the transfer of the data to the second repository when the identity of such second repository is confirmed by the data port device. A data integrity check confirms that only the designated to be transferred data was actually transferred to the second repository designated in the work order.

Abstract: A secure optical information disc comprising an electronic article surveillance tag embedded within a recess of a substrate of the disc structure is disclosed. The tag is placed within the recess such that it does not interfere with reading optically encoded information using a laser beam pick-up assembly such as those used to read DVD, CD, HD and Blu-Ray (BD) discs. The tag is placed within a recess having either no inner wall or an inclined wall.

Abstract: A secure optical data disc comprising an electronic article surveillance tag embedded within a layered disc structure comprising first and second substrates is disclosed. The tag is placed within a non-readable zone (i.e., one that does not have data tracks) of the secure disc. Layer-wise, the tag is either sandwiched between the two substrates or alternatively embedded within one of the two substrates. In the case where the tag is sandwiched between first and second substrates, a bonding layer occupies a space radially outward from the tag. The bonding layer holds the first and second substrates together thereby forming the secure disc.

Abstract: A secure optical data disc comprising an electronic article surveillance tag embedded within a layered disc structure comprising first and second substrates is disclosed. The tag is placed within a non-readable zone (i.e., one that does not have data tracks) of the secure disc. To improve signal quality of the tag, the reflective metal layer thickness is minimized and discontinuities are introduced on the reflective metal layer. A first discontinuity separates a data track region of the disc from a mirror/ID band region. A second, radial discontinuity opens the mirror/ID band ring.
