New patents are issued by the USPTO on Tuesdays. Today's Spotlight Patents concern aspects of digital fingerprinting and digital watermarking. Assigned to Google, the first of today's patents concerns techniques for the detection of potentially copyrighted content in user-initiated live streams. Assigned to Digimarc, the second patent concerns techniques for watermarking different areas of digital images with different intensities.
9,398,052, "Detection of potentially copyrighted content in user-initiated live streams," assigned to Google.
Systems and methods modifying a presentation of media content in response to a detected violation are provided. In particular, media content such as a media stream broadcasted by a user to other users can be monitored. The broadcasted media stream can be fingerprinted and compared to a fingerprint repository that includes entries associated with media content that is copyrighted or otherwise considered a violation. If the fingerprint matches entries included in the fingerprint repository, then the media stream can be modified such as modified to terminate.
9,396,510, "Watermarking different areas of digital images with different intensities," assigned to Digimarc.
The disclosure relates to data hiding and digital watermarking in imagery. One claim recites an apparatus comprising: memory storing an image editing program; an input for receiving imagery, the imagery comprising image features that vary across the imagery; a processor configured for: encoding a pattern of 2-dimensional auxiliary data at a first intensity within a first multi-dimensional region within the imagery; and encoding the pattern of 2-dimensional auxiliary data at a second, different intensity within a second multi-dimensional region within the imagery. Of course, other claims and combinations are provided.
