The PTO publishes new pending patent applications on Thursdays. Both of today's Spotlight Applications concern aspects of digital watermarking . Assigned to Digimarc, the first of today's applications discloses techniques for economically secure digital mass media systems. Assigned to Fujitsu (JP), the second application discloses techniques for interactive advertising using digital watermarks.
20140344574, "Economically secure digital mass media systems," assigned to Digimarc.
Content is encoded with a watermark that associates it with a particular consumer. When presented for playback, the rendering equipment examines the watermark to confirm that the consumer with whom the content is associated, is also the consumer with whom the equipment is associated. If there is no watermark--or if the watermark is associated with a different consumer, then playback is refused. The equipment also desirably checks whether the content has a second watermark (or even a very feeble remnant thereof), indicating that the content has been derived from content earlier provided to a different consumer. If so, playback is again refused. Thus, this embodiment will refuse to play if there is no watermark; if there is one watermark not associated with the proprietor of the equipment; or if there are two or more watermarks.
20140344033, "Interactive advertising using digital watermarks," assigned to Fujitsu (JP).
A method and system for interactive advertising may use digital watermarks embedded in multimedia content displayed to a user of a mobile device that includes a camera. The user may capture the digital watermark by simply recording the multimedia content using the camera on the mobile device. A digital watermark value obtained from the digital watermark may be sent to a watermark service provider who validates the digital watermark value and returns an advertising token to the mobile device. The advertising token may be usable by the user to receive promotions, offers, and other information associated with an advertiser.
