    Abstract: A self-authenticating intelligent document in sheet medium form has an information storage and transfer means incorporated thereinto for storing the original text portion of document information formed on the surface of the sheet medium and for storing an image of the completed document after supplemental information has been added to the original text portion on the surface of the sheet medium. The information storage and transfer means is either a single RFID tag having a first memory portion for storing the text portion and a second memory portion for storing the image of the completed document; or a first RFID tag having a memory portion for storing the text portion and a second RFID tag for storing the image of the completed document. To verify the authenticity of the document, the image stored in the information storage and transfer means is read out and compared with the visible version. When the two are identical, the document is authentic.

    Abstract: First and second patterns are formed on a substrate. A spatial offset between the patterns is determined, and stored for later use in authenticating the substrate. (One or both of the patterns may convey steganographic information. One pattern may be printed, while the other may be embossed.) A smartphone can sense these patterns, determine the spatial offset, and check whether the determined offset matches the earlier-stored offset, to judge whether the substrate is authentic. Another arrangement effects serialization of product packaging by use of paired patterns (at least one of which is typically a watermark pattern) applied in a manner causing a spatial offset between the patterns to progressively vary along a length of a printed web. Still other arrangements involve substrates conveying patterns that degrade over time, e.g., indicating freshness or pressurization condition. A great variety of other features and arrangements are also detailed.

    Abstract: The present invention is a method and apparatus for protection of various items against counterfeiting using physical unclonable features of item microstructure images. The protection is based on the proposed identification and authentication protocols coupled with portable devices. In both cases a special transform is applied to data that provides a unique representation in the secure key-dependent domain of reduced dimensionality that also simultaneously resolves performance-security-complexity and memory storage requirement trade-offs. The enrolled database needed for the identification can be stored in the public domain without any risk to be used by the counterfeiters. Additionally, it can be easily transportable to various portable devices due to its small size. Notably, the proposed transformations are chosen in such a way to guarantee the best possible performance in terms of identification accuracy with respect to the identification in the raw data domain. The authentication protocol is based on the proposed transform jointly with the distributed source coding. Finally, the extensions of the described techniques to the protection of artworks and secure key exchange and extraction are disclosed in the invention.

    Abstract: A portable token and systems and methods for identification and authentication of the same are disclosed. The portable token may be utilized for a variety of purposes and uses a thin section of rock as a unique identifying element, which is extremely resistant to forgery or duplication. Identification and authorization of tokens is achieved by a system that uses optical examination of the microstructure and the refractive properties of crystalline minerals within the identifying element, by transmitted polarized light techniques. Comparison between stored reference data and acquired examination data is the basis for verifying authenticity. The naturally-occurring three-dimensional orientations of the optical axes of mineral crystals contribute to the identification information by their effects.

    Abstract: 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.
