On Tuesdays the USPTO issues new patents. Today's Spotlight Patents address aspects of digital fingerprinting and watermarking. Assigned to Shutterfly, the first patent concerns techniques for the automated verification of copyrighted digital images. Assigned to Microsoft, the second patent concerns a centralized detector of dynamic, robust, embedded-signals.
A computer-assisted method for detecting copyright protection in digital images receives a digital image, searches for capture device information associated with the digital image, calculates one or more image characteristics of the digital image, and verifies copyright ownership and usage authorization of the digital image in response to the capture device information and the calculated image characteristics.
7,493,490, "Centralized detector of dynamic, robust, embedded-signals," assigned to Microsoft.
Described herein is a technology for dynamic and robust detection of one or more embedded-signals (e.g., watermark, copyright notice, encoded data, etc.) in an input signal (e.g., multimedia stream, video stream, audio stream, data, radio, etc.) within a multi-signal environment. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
