摘要： The present invention provides methods and systems for authenticating identification documents. We also teach an identification document including two or more digital watermarks. The watermarks correspond with each other or with indicia carried by the identification document. The correspondence can be verified to determine authenticity. We also provide digital watermark detection methods and systems to identify the different watermarks through embedded orientation components. We then focus watermark message-decoding efforts on areas identified as likely including watermark orientation components. In another implementation we provide a watermark detection trigger to identify so-called legacy documents. The trigger may indicate the presence or expected absence of a digital watermark. In other implementations we provide a versatile document authenticator to toggle between watermarking and non-watermarking authentication processes depending on a detection trigger. Other implementations are provided as well.

摘要： Directional albedo of a particular article, such as an identity card, is measured and stored. When the article is later presented, it can be confirmed to be the same particular article by re-measuring the albedo function, and checking for correspondence against the earlier-stored data. The re-measuring can be performed through us of a handheld optical device, such as a camera-equipped cell phone. The albedo function can serve as random key data in a variety of cryptographic applications. The function can be changed during the life of the article. A variety of other features are also detailed.

摘要： A watermarked signal is pre-filtered based on an analysis of signal characteristics that identify filter parameters that yield better correspondence between the filtered watermarked signal and the digital watermark. The watermark detection method computes signal characteristics of a host digitally watermarked signal, and analyzes the characteristics to determine an extent to which the signal characteristics correspond to characteristics of the digital watermark. The method adapts parameters of digital watermark prediction applied to the watermarked signal based on the extent to which the signal characteristics correspond to the characteristics of the digital watermark. In one embodiment, different filters or filter parameters are selected to match different signal characteristics of the watermarked signal with the characteristics of the digital watermark.

摘要： A duplex visual tester for testing multiple fiber optic cable runs includes a housing having a first LED and a second LED in a duplex fiber connection. The first LED and the second LED are in electronic communication with a power source, a battery, an on/off switch, and a timer configured to pulse the first LED and the second LED. The first LED and the second LED are installed in the duplex fiber connection. The first LED has a first color, and the second LED has a second, different color, wherein the first color and the second color have the same luminosity. Preferably, the timer pulses the first LED and the second LED at between eight and ten Hz, such that the first color and second color can be seen in the fiber optic cable run.

摘要： THE present invention relates to steganography and digital watermarking. In one implementation, we provide a method to analyze a digital image to determine whether the digital image will be a suitable host to receive steganographic encoding or digital watermarking. Suitability is determined, at least in part, by analyzing the digital image relative to an expected workflow process through which a watermarked version of the digital image is expected to flow through. Our methods and systems determine whether the digital image forms a suitable host to receive digital watermarking relative to the expected workflow process. If the digital image is not suitable, the digital image is modified to better receive digital watermarking in anticipation of the expected workflow process.
