On Thursdays the USPTO publishes new pending patent applications. Today's Sportlight Applications concern aspects of digital watermarking and digital fingeprinting. Assigned to Sharp (JP), the first application discloses image processing techniques including watermarking. Assigned to IBM, the second application discloses techniques for locating documents for providing data leakage prevention within an information security management system
20120082337, "Image processing apparatus, image forming apparatus, recording medium and image processing method," assigned to Sharp Kabushiki Kaisha (JP).
When original image data obtained by reading an original document is to be joined with watermark data associated with a watermark for copy control which appears as a result of making a copy, whether the original document includes a chromatic color or not is determined on the basis of the original image data. When the original document includes a chromatic color, the original image data is joined with chromatic watermark data. When the original document includes an achromatic color, the original image data is joined with achromatic watermark data.
20120084868, "Locating documents for providing data leakage prevention within an information security management system," assigned to IBM.
A method for locating documents has a step of, on each entity of the plurality of document-storing entities, calculating a respective fingerprint for each document of the documents stored on the entity, a step of transferring the calculated fingerprints by the entities to a data localization server having a fingerprint database for storing the transferred fingerprints, and a step of, at the data localization server, locating copies of a specimen document by calculating a fingerprint of the specimen document and comparing the calculated fingerprint of the specimen document with the fingerprints stored in the fingerprint database.
