On Thursdays the USPTO publishes new pending patent applications. Today's Spotlight Applications concern aspects of digital watermarking and digital fingerprinting. Assigned to Samsung, the first application discloses watermarking techniques for tracking hacked content and for blocking hacking of content. Assigned to Rovi, the second application discloses techniques for automated discovery of content and metadata.
20120272327, "Watermarking method and apparatus for tracking hacked content and method and apparatus for blocking hacking of content using the same," assigned to Samsung (KR).
Watermarking method and apparatus for tracking hacking and method and apparatus for blocking hacking of content are provided. The watermarking method includes: obtaining device information from a reception device, with which content is shared, through a determined network channel; generating watermark data based on the obtained device information; and generating watermarked multimedia content by inserting the generated watermark data into content. The method of blocking hacking of content includes: if hacked content is found, detecting watermark data from the hacked content; detecting transmission and reception device information from the detected watermark data; and extracting a progress route of the content based on the detected transmission and reception device information and performing revocation on a hacked device.
20120271823, "Automated discovery of content and metadata," assigned to Rovi Technologies Corporation.
A system for discovering content and metadata includes a processor communicatively coupled to a communication network and a database. The processor determines whether an end portion of a portion of content has been received based on the portion of content and/or metadata. The processor generates a content fingerprint based on the portion of content if the end portion has been received. The content fingerprint and/or the metadata are stored in the database.
