New pending patent applications are published by the USPTO on Thursdays. Today's Spotlight Applications concern aspects of digital watermarking and digital fingerprinting. Assigned to Philips Lighting, the first application discloses techniques related to an image handling module for protecting an image of a scene captured by a camera. Assigned to Sorenson Media, the second application discloses techniques using fingerprint layouts for content fingerprinting.
20170270630, "Watermarking system and method," assigned to Philips Lighting Holding B.V. (NL)
A device comprises an image handling module for protecting an image of a scene captured by a camera. The image handling module is configured detect, in association with the image, a watermark signal having been embedded in light illuminating the scene at a respective geographic location. Further, the image handling module is configured to lookup the detected watermark signal in a privacy database, and based thereon to selectively inhibit use of the image.
20170272814, "Fingerprint layouts for content fingerprinting," assigned to Sorenson Media, Inc.
A method is disclosed for identifying the media content. The method includes receiving fingerprint media content from a content provider to obtain a first set of fingerprints, the first set of fingerprints including a first subset of fingerprints in a first fingerprint layout and a second subset of fingerprints in a second fingerprint layout. The method can include receiving a second set of fingerprints for media content displayed on the electronic device, the second set of fingerprints comprising a third subset of fingerprints in the first fingerprint layout and a fourth subset of fingerprints in the second fingerprint layout. The method can include matching a first fingerprint in the first subset of fingerprints to a second fingerprint in the third subset of fingerprints or a third fingerprint in the second subset of fingerprints to a fourth fingerprint in the fourth subset of fingerprints in order to identify the media content.
