| 20090065568 | Systems and Methods for Associating Production Attributes with Products - Methods are provided for marking products with unique identification codes, associating times with at least some of the unique identification codes, and associating other times with certain events pertaining to the production of the marked products. These times can be used to subsequently determine whether a marked product belongs to a population that was produced before or after an event. | 03-12-2009 |
| 20090144534 | Data Processing Systems and Methods - Various improvements to data processing systems involve enhancements to BIOS functionality, use of identifiers associated with specific instances of hardware, and data hiding techniques—sometimes alone, sometimes in combination. Many of these improvements can be applied to increase the security of computer systems, and networks of which they form part. | 06-04-2009 |
| 20090232352 | Steganographic Encoding Methods and Apparatus - The presently claimed invention relates generally to steganographic encoding. One claim recites a method including: obtaining data representing a first graphic; utilizing a multi-purpose computer processor configured for steganographically data hiding to hide a signal in the data representing the first graphic; obtaining a copy of the first graphic including a steganographically hidden signal therein; storing the copy of the first graphic in electronic memory or integrated circuitry. A steganographically hidden signal in the data representing the first graphic and the steganographically hidden signal in the copy of the first graphic are related. Of course, other combinations are provided as well. | 09-17-2009 |
| 20100142752 | Signal Processing of Audio and Video Data, including Deriving Identifying Information - The present invention relates generally to signal processing of media content, e.g., audio or video content. One form of signal processing derives identifying information from media content. One claim recites a method including: upon encountering audio or video content, and using a programmed electronic processor, attempting to derive identifying information from data representing the encountered audio or video content; if a digital watermark is not obtained from the data representing the encountered audio or video content, modifying the encountered audio or video content; and then attempting to attempting to derive identifying information from data representing the modified audio or video content. Of course, other claims are provided too. | 06-10-2010 |
| 20100146285 | Digital Watermarks - The present invention relates generally to digital watermarking and steganographic data hiding. In one embodiment a method of rendering content to a user is provided. The rendered content includes a digital watermark embedded therein. In another embodiment, digital watermarking is utilized to facilitate purchase or lease of audio or video content over a network or with a remote computer. In still another embodiment, a compression characteristic is determined, and subsequent steganographic embedding is influenced based on the characteristic. Other embodiments are provided as well. | 06-10-2010 |
| 20100310118 | Printing Media and Methods Employing Digital Watermarking - Stationery, or other printable media, is encoded with a digital watermark. The watermark is not conspicuous to a human observer of the media, yet conveys plural bits of auxiliary information when optically scanned and digitally processed. The watermark can be formed by ink-jet printing, or otherwise. The encoded information can be used for various purposes, including authenticating the document as an original, linking to associated on-line resources, and distinguishing seemingly-identical versions of the same document (document serialization). | 12-09-2010 |
| 20110058707 | Digital Watermarks - The present invention relates generally to information encoding, data hiding, steganography and digital watermarking. One claim recites: using a programmed electronic processor, encoding content with a plural-bit digital watermark in accordance with initial encoding parameters; determining an assessment of the encoded plural-bit digital watermark in each of two or more portions of the content; for each of the two or more portions of the content, adjusting at least one of the initial encoding parameters according to a determined assessment for a respective portion of the content; and using a programmed electronic processor, encoding the content with said plural-bit watermark in accordance with adjusted encoding parameters. Other claims are provided as well. | 03-10-2011 |
