Abstract:
A system and method for verifying that a document is included in a document management system is disclosed. This system and method includes scanning of a scan track of a document, generating document data dependently upon the scanning, comparing the generated document data to stored document data, the stored document data generated dependently upon a prior scanning of the scan track of the document, and outputting an indication of the document being included in the document management system as determined by the comparing.
Abstract:
A verifiable security document system, which generates a security architecture from the sensitive information, by applying a security platform equipped with secure print media and secure print configurations for printing of the security architecture on a document to form an anti-counterfeit, protected document. The security of the document system is further heighted by communications between the validation center and the document issuer and between the validation center and recipient of the document.
Abstract:
A control device is configured to: control the scanner unit, when a first instruction is received from a user to insert a first scanned data in a first file stored in a file storage server, to scan a document to generate the first scanned data; and to provide a first insertion request to the file storage server through a communication interface, the first insertion request requesting the file storage server to insert the first scanned data at a target location in the first file, the target location being a location designated by the user through a terminal device that is configured separately from the control device.
Abstract:
Methods and systems rasterize a document to produce a bitmap having first pixels of a first color as background uniformly located across a watermark region and second pixels of a second color located in a pattern forming foreground items within the watermark region. The rasterization causes the first pixels to deposit a first marking material (forming the first color) to a first height on the print media, and the rasterization causes the second pixels to deposit a second marking material (forming the second color) to a second height (different from the first height) on the print media. In the printed document, by having the first color be different from the second color and the second height be different from the first height, this causes the relative darkness between the background and the foreground items to reverse when the printed document is viewed from different angles (relative to a light source).

Abstract:
The disclosure relates to processing content with watermarks to generate watermarked versions. In some aspects, each version may be different. Groups of fragments may be combined to generate a unique stream by pulling fragments from two or more of the groups of fragments. Further, fragmenting may be performed before watermarking, and fragments may be pulled and watermarked upon request.
Abstract:
The present invention relates generally to information encoding, data hiding, steganography and digital watermarking. One claim recites: using a programmed electronic processor, encoding content with a plural-bit digital watermark in accordance with initial encoding parameters; determining an assessment of the encoded plural-bit digital watermark in each of two or more portions of the content; for each of the two or more portions of the content, adjusting at least one of the initial encoding parameters according to a determined assessment for a respective portion of the content; and using a programmed electronic processor, encoding the content with said plural-bit watermark in accordance with adjusted encoding parameters. Other claims are provided as well.
Abstract:
An image processing apparatus includes an extraction unit configured to extract a feature amount from information recorded on a recording medium, an acquisition unit configured to acquire an identification image identifying an operator of the recording apparatus, a storage unit configured to store the feature amount and the identification image, wherein the identification image is associated with the feature amount, a search unit configured to compare a feature amount extracted from a predetermined medium by the extraction unit with the feature amount stored in the storage unit, wherein, based on a result of the comparison, the identification image associated with the stored feature amount is associated with the predetermined medium, and an output unit configured to output the identification image associated with the predetermined medium.
Abstract:
A media object authentication system uses layers of security features based on digital watermarks embedded in media objects. The system generates a first digital watermark with a message payload carrying data about the object, such as a hash of text data printed on the object. The first digital watermark is combined with a content signature derived from features of the media object, such as frequency domain attributes, edge attributes, or other filtered version of the media signal (e.g., image photo on a secure document) on the media object. This combination forms a new digital watermark signal that is embedded in the host media object. To verify the object, the digital watermark payload is extracted and compared with the data about the object. The combined digital watermark and content signature is also evaluated to authenticate the media signal on the media object.
Abstract:
A portable device uses a microphone to listen to ambient audio, derives data from captured audio signals, and uses the derived data to request delivery of the audio or related information to the user's home or other location. The device is desirably pocket-sized, or suitable for carrying on a key-ring. The device may also detect a watermark signal that is present in the user's environment (e.g., played through a public address speaker system) to aid the user in recalling the context from which the audio was requested.
