New pending patent applications are published on Thursdays. Today's Spotlight Applications concern aspects of digital watermarking and digital fingerprinting. Assigned to IBM, the first of today's applications addresses techniques for increased security using dynamic watermarking. Assigned to Gracenote, the second application addresses techniques for media channel identification with multi-match detection and disambiguation based on location.
20190180008, "Increased security using dynamic watermarking," assigned to IBM.
Abstract
As disclosed herein is a tool for enabling dynamic watermarking on a client, including a computer determining a negotiated watermarking algorithm that identifies at least one location on a web page for a placed watermark, and initiating a web communication by requesting a web page. The computer receives the web page, and verifies the authenticity of the web page using the negotiated watermarking algorithm prior to displaying of the web page. Also disclosed herein is a tool for enabling dynamic watermarking on a server which includes determining a negotiated watermarking algorithm that identifies at least one location on a web page for a placed watermark, receiving a request for a web page from a client, and identifying the client.
20190182539, "Media channel identification with multi-match detection and disambiguation based on location," assigned to Gracenote.
Abstract
Disclosed are methods and systems involving location-based disambiguation of media channel identification, in a scenario where a fingerprint of media content being rendered by a media presentation device matches multiple reference fingerprints corresponding respectively with multiple different media channels. Upon detecting such a multi-match situation, a server or other entity will use a location of the media presentation device as a basis to disambiguate between the matching reference fingerprints and thus to determine the channel on which the media content being rendered by the media presentation device is arriving.
