摘要： A portable device, such as a cell phone, is used to "forage" media content from a user's environment For example, it may listen to a television viewed by a traveler in an airport lounge By reference to digital watermark or other data extracted from the content, the device can identify the television program, and enable a variety of actions For example, the device may instruct a DVR to record the remainder of the television program - or determine when the program will be rebroadcast, and instruct the DVR to record the program in its entirety at that later time The device may also identify content that preceded (or follows) the foraged content Thus, a user who tunes-?n just at the end of an exciting sporting event can capture one of the following commercials, identify the preceding program, and download same for later viewing

摘要： Multiple digital watermarks, each of which has different characteristics, are embedded in a document. The characteristics of the various watermarks are chosen so that each of the watermarks will be affected in a different manner if the document is subsequently copied and reproduced.The detection process or mechanism reads each of the watermark and compares their characteristics. While wear and handling may change the characteristics of the digital watermarks in a document, the relationship between the characteristic of multiple digital watermarks in a document will never-the-less give an indication as to whether a document is an original or a copy of an original.

摘要： Una caracteristica de seguridad para un documento de identificacion y metodo para fabricarla, proporcionan capas de seguridad que incluyen, por ejemplo, manipulacion evidente, efectos opticamente variables, e informacion personalizada que enlaza la informacion de seguridad con el documento y su portador. La caracteristica se forma al imprimir un primer material que representa la primera informacion en una capa central del documento. Este primer material cubre por lo menos parcialmente la capa central. Un ejemplo es impresion Xerografica de informacion sobre el solicitante del documento de ID y la fotografia del solicitante. El proceso entonces aplica un segundo material que representa la segunda informacion que por lo menos parcialmente recubre el primer material, y cura el segundo material. Un ejemplo es impresion por chorro de tinta de informacion personal con una tinta curable por UV en forma de un diseno en relieve en la capa central. Finalmente, el proceso aplica una capa de laminado sobre la capa central. La capa de laminado cubre el primero y segundo materiales. El primero y segundo materiales se adhieren en forma diferente a las capas de laminado y central de tal manera que la remocion de la capa de laminado de la capa central provoca una separacion del primero y segundo materiales. El diseno en relieve se forma para dar al documento una sensacion tactil y tambien crear efectos opticamente variables.

摘要： METHOD AND APPARATUS FOR "COPY-ONCE" OF A DIGITAL VIDEO SIGNAL USES A WATERMARK IN THE VIDEO SIGNAL. THE EMBEDDED WATERMARK HAS TWO VERSIONS: ONE INDICATES COPY-NEVER AND A SECOND INDICATES COPY-ONCE, THE DIFFERENCE BEING A SINGLE WATERMARK BIT. THE WATERMARK CARRIES ADDITIONAL BITS REPRESENTING A DIGITIZED ATTRIBUTE (IMAGE CHARACTERISTIC) OF A PARTICULAR VIDEO FRAME OF THE VIDEO SIGNAL, FOR INSTANCE AN AVERAGE VALUE IF THE AMPLITUDE OF A VIDEO FIELD. THE FRAME WHOSE ATTRIBUTE IS CARRIED IN THE WATERMARK HAS A FIELD (OR FRAME) MARKER, WHICH IS A SPECIAL SIGNAL LOCATED IN THE OVERSCAN PORTION OF THE FRAME. A COMPLIANT VIDEO RECORDER VERIFIES THE WATERMARK AND THE COPY-ONCE BIT, EXTRACTS THE ASSOCIATED ATTRIBUTE FROM THE WATERMARK, AND COMPARES IT TO THE MEASURED ATTRIBUTE OF THE MARKED VIDEO FRAME. ONLY IF THE EXTRACTED ATTRIBUTE VALUE AND THE MEASURED ATTRIBUTE VALUE MATCH IS RECORDING ENABLED. DURING THE RECORDING PROCESS, THE FRAME MARKERS ARE STRIPPED, PREVENTING SECOND GENERATION COPIES OF THE RECORDED VIDEO SIGNAL, AND THE COPY-ONCE BIT IS SET TO COPY-NEVER.

摘要： Security documents (e.g. passports, currency, event tickets, and the like) are encoded to convey machine-readable multi-bit binary information (e.g. digital watermark), usually in a manner not alerting human viewers that such information is present. The documents can be provided with overt or subliminal calibration patterns. When a document incorporating such a pattern is scanned (e.g. by a photocopier), the pattern facilitates detection of the encoded information notwithstanding possible sealing or rotation of the scan data. The calibration pattern can serve as a carrier for the watermark information, or the watermark can be encoded independently. In one embodiment, the watermark and the calibration pattern are formed on the document by an intaglio process, with or without ink. A photocopier responsive to such markings can take predetermined action if reproduction of a security document is attempted. A passport processing station responsive to such markings can use the decoded binary data to access a database having information concerning the passport holder. Some such apparatuses detect both the watermark data and the presence of a visible structure characteristic of a security document (e.g., a printed seal of the document's issuer).

摘要： The present invention relates generally to identification documents. One claim recites an apparatus to authentic an identification document. The identification document comprising first machine-readable information including a first plural-bit message, and semantic information carried on or in the identification document. The apparatus includes: a first reader to read the first machine-readable information to obtain the first plural-bit message; a second reader to obtain information from the semantic information carried on or in the identification document; an electronic processor programmed as a decryption unit to decrypt the first plural-bit message or the information obtained from the semantic information; and an electronic processor programmed as a decision unit to determine whether the identification document is authentic based at least in part on the first plural-bit message and the semantic information. Other claims and combinations are provided as well.
