The PTO issues new patents on Tuedays. Both of today's Spotlight Patents concern aspects of digital watermarking. Assigned to Texas Instruments, the first patent addresses techniques for watermarking digital media. Assigned to The Telos Alliance, the second patent addresses techniques related to feedback and simulation regarding detectability of a watermark message.
8,917,899, "Methods and systems for watermarking digital media," assigned to Texas Instruments.
A system is provided that includes a processor and a network interface coupled to the processor. The system also includes a system memory coupled to the processor. The system memory stores watermarking instructions that, when executed, cause the processor to mark digital media with information that identifies the system.
8,918,326, "Feedback and simulation regarding detectability of a watermark message," assigned to The Telos Alliance.
Providing feedback regarding detectability of a watermark message produced by a watermarking encoder may include receiving a watermark detectability indication corresponding to detectability of the watermark message, and determining an enhancement indication corresponding to a prescribed enhancement to a watermark signal in which the watermark message is embedded based on the watermark detectability indication.
