On Tuesdays the USPTO issues new patents. Today's Spotlight Patents address aspects of digital fingerprinting and watermarking. Assigned to BayTSP.com, the first patent concerns techniques for managing, reviewing, comparing and detecting data on a wide area network. Assigned to Digimarc, the second patent concerns techniques for digital watermarking compressed video captured from aerial sensors.
Embodiments of the present invention are directed to a data management system, apparatus and process for uniquely identifying and protecting data. In preferred embodiments, the data management system comprises a data management server, a key generator, a source print generator and a source print detector. In some preferred embodiments, the data management system further comprises a data embedding system. Keys are created by the data management system for application to source files to create a fingerprint for the source file. The fingerprint is compared to unknown files to identify uses of the source file.
7,650,008, "Digital watermarking compressed video captured from aerial sensors," assigned to Digimarc.
Digital watermarking technology is used in conjunction with compressed video captured from aerial, unmanned apparatus, such as satellites and aircraft. One implementation includes a method of capturing video depicting at least a portion of the earth's surface, the video captured by an aerial, unmanned apparatus; compressing the captured video; and hiding a first digital watermark in the compressed captured video through alterations to data representing the compressed video. The first digital watermark is generally imperceptible to a human observer of the video. And the digital watermark has a plural-bit payload including at least geographical metadata associated with the captured video. Other implementations are also provided.
