On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital watermarking. Assigned to Canon, the first application disccloses an image forming device and image forming method. Assigned to Intel, the second application discloses and advanced watermarking system and methond.
20120257253, "Image forming device and image forming method," assigned to Canon (JP).
Abstract
If a fallback processing involving lossy compression occurs in PDL data including a special pattern, such as a texture pattern, an electronic watermark, or an Anoto pattern, the performance of the special pattern cannot be sufficiently exhibited by image degradation due to the compression. Moreover, in order to obtain an image quality capable of sufficiently exhibiting the performance of the special pattern, a high-capacity memory is necessary to raise the cost. Document information and additional information are sequentially received from other device, and a pre-preparation processing for bit-mapping the document information is started, and upon receipt of the additional information by a receiving unit, a bit map is generated using the information (display list) obtained by the pre-preparation processing for the document information. The generated bit map is compressed and the compressed bit map is associated with the information that is obtained by the pre-preparation processing for the additional information.

Abstract
A method, computer program product, and computing device for obtaining an uncompressed digital media data file. One or more default watermarks is inserted into the uncompressed digital media data file to form a watermarked uncompressed digital media data file. The watermarked uncompressed digital media data file is compressed to form a first watermarked compressed digital media data file. The first watermarked compressed media data file is stored on a storage device. The first watermarked compressed media data file is retrieved from the storage device. The first watermarked compressed digital media data file is modified to associate the first watermarked compressed digital media data file with a transaction identifier to form a second watermarked compressed digital media data file.
