On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital fingerprinting and digital watermarking. Assigned to Akamai, the first application discloses a dynamic multimedia fingerprinting system. The second application discloses techniques for digital watermarking.
20090259853, "Dynamic multimedia fingerprinting system," assigned to Akamai.
Abstract
A dynamic multimedia fingerprinting system is provided. A user requests multimedia content from a Web cache server that verifies that the user is authorized to download the content. A custom fingerprint specific to the user is generated and dynamically inserted into the content as the content is delivered to the user. The custom fingerprint can be generated on the Web cache server or at the content provider's server. The system allows a content provider to specify where the custom fingerprint is inserted into the content or where the fingerprint is to replace a placeholder within the content.
20090260061, "Symbiotic network digital document layering and/or steganography method, article and apparatus," no assignee given.
Abstract
What is provided are methods, articles and apparatuses for digital document layering, watermarking holding messages, and/or general steganography over a symbiotic network.
