Abstract: A workpiece authentication system uses shape recovery techniques to extract explicit three dimensional ("3-D") features of the surface geometry of the designated portion of a workpiece from images produced using different lighting conditions. The system then bases authentication on the 3-D surface features. The system recovers surface normals, or equivalently gradients, for selected locations within a designated portion of the workpiece from multiple enrollment images produced under different illumination conditions. The system then encodes the surface normal information into authentication indicia that is placed on the workpiece and/or stores the surface normals or related information. Thereafter, the system determines that a given workpiece is authentic if the surface normals recovered from various verification images correspond to the stored surface normal information or the surface normal information encoded into the indicia. Alternatively, the system may use the surface normals to predict what an image should contain when the workpiece is subjected to a particular lighting condition. The system then determines that the workpiece is authentic if the predicted image and the image produced using the workpiece correspond. The system may instead encode brightness patterns associated with one or more enrollment images into the indicia. The system then recovers surface normals from images produced during verification operations, predicts what the brightness image should contain and compares the enrollment image to the prediction.

Abstract: An encoding system (100) includes data in an underlying image by controlling or modifying halftone settings, which are used in the associated printing color process to produce a hard-copy document or an on screen image. The system (100) uses a halftone encoder (104) to encode the data into the image by selectively varying, in accordance with the data, the order of various color channels, and/or the screen angles using an angle table (105o) and/or spatial frequencies, or scales using a scale table (105r), of associated halftone screens. The system (100) encodes an N-bit payload in the image at the halftone encoder (104) by modifying the halftone settings of certain or all of the color channels in accordance with the data, thus using the color channels also as "data channels." The system (100) prints the encode image at a printer (108) by incorporating the modified halftone settings into the respective halftone screens, and applying the inks in a conventional manner.

Abstract: A system integrates mailing label and/or postage purchasing systems with information that is available locally at a user's workstation or local network and also information that is available globally through a postal service server. The system obtains mailing addresses locally from the user or user's network and/or globally from a postal service server. The system may thus provide an address from the user's workstation and then a more current or appropriate mailing address, based on information available through the postal service. Further, the system maintains the postage and mailing label information supplied by the user in a session that either concludes when the user prints postage stamps and mailing labels locally or continues to allow the user to print or otherwise obtain the postage and mailing labels at a Post Office that communicates with the postal service server. The system also makes available to the user other services that the system funds through a user's postage account. The system may provide services, suchas, money transfers, crediting telephone cards, and so forth, and debit the user's postal account accordingly. The system may also send status messages to the user, an intended recipient or both evidencing the transfer or delivery of funds, mail pieces, and so forth. Further, the system may be combined with a personal mail piece tracking and tracing system, to provide the user with other services that are based, in whole or in part, on information maintained by or under the control of the postal sercice.

Abstract: An inhomogeneous, optically active medium with optically active components, such as, an ink with reflective flakes or a gemstone dust, is included on or embedded in one or more portions of a workpiece. When the portions are illuminated with visible and/or ultraviolet light, the components, which are also anisotropic, provide readily detectable information that can be extracted for a string which is included on or associated with an indicium that is used to authenticate the workpiece. To verify the workpiece, the one or more portions that contain the optically active medium are again illuminated, and the string is then newly generated from various images of the appearances of the components. The newly generated string or, as appropriate, an indicium that is based on the string is then compared with a string or an indicium that is imprinted on or associated with the workpiece. If the previously and newly generated strings or indicium correspond, the workpiece is determined to be authentic. Otherwise, the workpiece is deemed to be a counterfeit.

Abstract: An optically active medium with optically active components is included on or embedded in one or more portions (89) of a workpiece. When the portions are illuminated with visible and/or ultraviolet light, the components provide readily detectable information that can be extracted for a string which is included on or associated with an indicium that is used to authenticate the workpiece. To verify the workpiece, the one or more portions that contain the optically active medium are again illuminated, and the string is then newly generated from various images of the appearances of the components. The newly generated string or an indicium that is based on the string is then compared with a string or an indicium that is imprinted on or associated with the workpiece. If the previously and newly generated strings or indicium correspond, the workpiece is determined to be authentic.

Abstract: A system for encoding data into and decoding data from a coded pattern using angular symbology (18) in which symbols are represented by angular orientations of data modulation patterns relative to a reference modulation pattern. The modulation patterns are selected to have components (20) that are localized in a Fourier transform domain (34). To decode the coded pattern the system performs a two-dimensional fast Fourier transform and identifies the spatial frequencies and relative angular orientations associated with the respective modulation patterns.
