New patent applications are published on Thursdays by the USPTO. Both of today's Spotlight Applications concern aspects of digital watermarking. Assigned to Civolution, the first application discloses techniques for watermarking content prior to fragmenting. Assigned to Digimarc, the second application discloses techniques for steganographic [watermarking] encoding and decoding.
20160156994, "Method and system for watermarking content prior to fragmenting," assigned to Civolution (NL).
Abstract
In a method of distributing content in plural fragments, each fragment being no longer than a given maximum fragment length, a method of watermarking the content prior to fragmenting the content into the plural fragments, comprising water-marking a given payload symbol from a given alphabet in a given segment of the content, and treating a segment prior to or following the given segment as an intermediary segment, the length of this intermediary segment being substantially equal to or greater than the maximum fragment length.20160156805, "Steganographic encoding and decoding," assigned to Digimarc.
Abstract
This patent document relates generally to steganography and digital watermarking. One claim recites an apparatus comprising: electronic memory for buffering samples corresponding to a digital image; means for analyzing a digital image relative to an expected workflow process, the expected workflow process comprising optical capture of a printed version of the digital image, the digital image comprising data representing process colors CMY; means for applying tone correction to the digital image, said means for applying yielding an altered digital image; means for transforming the altered digital image with digital watermarking, the digital watermarking conveying a plural-bit message; and a processor configured for providing the transformed, altered digital image. Of course, other claims and combinations are provided too.
