    摘要: Digital watermark methods for encoding auxiliary data into a host signal are used to authenticate physical and electronic objects. In one implementation, an identification document includes electronic circuitry. The electronic circuitry includes an image of an authorized bearer of the identification document. The image includes first digital watermarking having a plural-bit identifier. In some cases, the identification document includes a printed image of the authorized bearer of the identification document. The printed image includes second digital watermarking therein. The first digital watermarking and the second digital watermarking can be cross-correlated for authentication of the identification document.

    摘要: A peripheral device for use with a computer system includes a housing adapted to fit within a user's palm, an optical sensor, a lens, circuitry for processing the signals from the sensor and producing corresponding output data, and a wireless link for relaying the output data from the peripheral device to the computer system. The sensor is useful in acquiring optically-encoded multi-bit information for use by the computer system. Another arrangement includes a substrate on which is formed both a 2D array of optical sensing elements, and a steganographic processor coupled to these elements to effect a steganographic operation. A variety of other novel technologies are also detailed.

    摘要: A mouse having X- and Y-position encoders, and associated circuitry for generating X- and Y-movement data, additionally includes an optical sensor for producing grey-scale image data, thereby allowing the mouse to serve both as a positioning device and an optical input device. Desirably, the substrate on which the optical sensor is formed also includes a steganographic decoder. This decoder can enable a variety of functionality, such as linking to web addresses steganographically encoded in print media (e.g., by subtle inking variations or by texture). In other embodiments, such a peripheral is provided without mouse-like functionality, and again permits reading machine-readable indicia printed in catalogs and the like.

    摘要: A number of novel watermarking applications, and improvements to watermarking methods, are disclosed. Included are techniques for encoding printed circuit boards and street signs with watermarks, deterring credit card fraud and controlling software licensing using watermarks, registering collectibles via watermarks, encoding the margins of printed pages with watermarks, and using watermarks to convey extra information in video by which fidelity of the rendered video may be improved. One particular arrangement is a method in which a PDA, wristwatch, or other portable device with a display screen presents a pattern that includes a machine-readable identifier. This image is sensed by a separate device, such as a webcam or a camera-equipped cell phone. The sensing device can then take an action based on the identifier. In some arrangements, the action is personalized to the user.
