Abstract: Methods and systems for tracking a physical object to identify or authenticate it utilizing digital fingerprints which are based on natural features extracted from a digital image of the object. Digital fingerprints do not require or rely on any labels, tags, integrated materials, unique identification characters, codes or other items that may be added to the object specifically for the purpose of identification. Consequently, the disclosed digital fingerprint techniques help to detect or prevent unauthorized alterations of documents, apparel, drugs and pharmaceuticals, etc. Further digital fingerprints can be used to better track and trace a wide variety of objects throughout the distribution chain to demonstrate their provenance and to detect counterfeit objects.

Abstract: Improvements are disclosed for detecting counterfeit objects, based on comparison to digital fingerprints that describe features found in images of objects known to be counterfeit.

Abstract: Improvements are disclosed for authentication of an object, verification of its provenance, and certification of the object as compliant with manufacturing standards. Or, an object may be reported as a suspected counterfeit. In one embodiment the system compares a digital fingerprint of the object, based in image capture, to digital fingerprints previously stored in a database and determines if the object has been registered before and is thus authentic. An object feature template may be created which has a list of features and attributes that are relevant for authenticating particular classes of objects. The object feature template can also be used to examine unregistered objects for signs of counterfeiting.

Abstract: Methods and systems for detecting changes, alterations and forgeries in documents utilize digital fingerprinting. A set of documents of a given type that are known to be altered or forgeries are scanned and “fingerprinted” to build a forgery database. Suspect documents are scanned and the resulting fingerprint data is used to query the forgery database to look for matching records, although a match need not be exact. Matches may be counted and compared to a threshold number to assess a confidence that a document is forged or not. The fingerprinting may be directed to at least one authentication region of a document, and one or more features in a region may be incorporated into a fingerprint of the document.

Abstract: This document describes predictive word completion. By predicting complete words after each user input on an input device, e.g., a virtual keyboard, a user may readily receive computer aid when inputting characters to increase accuracy and speed of the user's typing.

Abstract: Targets, target systems, and related methods are provided. The targets can provide non-electric or low electric dynamic imagery and/or thermal signature capabilities that can be used in target systems. For example, a target can include a substrate forming a target body and having a front side. A combined image is disposed on the front side of the substrate with the combined image including a combination of at least two primary images of a potential target provided through lenticular printing. A lenticular lens can be disposed over the combined image so that the combined image and the lenticular lens generate an observed image of the potential target body when viewed by an observer. Additionally or alternatively, a target can be provided that includes a substrate forming a target body and at least one substance disposed on the substrate configured to create a thermal signature mimicking a potential target.
