9,544,621, "Identification of captured videos," assigned to Google.
An identification system receives a request from a user device to identify a video captured in a video stream. The identification system identifies a display area captured in the video stream in which the video is displayed. The identification system identifies content include in the display area throughout the stream. Based on the identified content, the identification system creates a fingerprint for the video. The identification system identifies from a plurality of stored fingerprints at least one fingerprint similar to the created fingerprint. The identification system identifies video information associated with the similar fingerprint. The video information is transmitted to the user device and displayed as being video information about the video captured in the stream.
9,544,466, "Security compliance checking of documents," assigned to Xerox.
The disclosed embodiments provide for checking documents for security compliance when the documents are printed, scanned, or copied. A security status is determined based on security indicators within a document's content. Security indicators can be located within a document's text, figures, watermarks, security marks, and invisible marks. Security indicators can be found by comparing a document's content to a set of stored indicator descriptions. The indicators found are used to determine a document score and security responses are triggered based on the document score.
