Abstract: A method of authenticating an item is disclosed which includes applying light to an item, wherein the item includes a random distribution of fluorescent particles disposed thereon, capturing one or more images from the item, generating a cryptographic pattern from the one or more captured images by a host processing system, communicating the cryptographic pattern to a remote processing system having a plurality of cryptographic keys in a database each uniquely associated with a corresponding item, comparing the cryptographic pattern with the plurality of cryptographic keys in the database, and communicating a positive evaluation for authentication to the host processing system if a match is found between one of the plurality of cryptographic keys and the communicated cryptographic pattern.

Abstract: A method of generating a physically unclonable function (PUF) for pharmaceutical authentication is disclosed which includes generating an edible (PUF), affixing the edible PUF onto a pharmaceutical in a random distribution, and generating a cryptographic key based on the randomly distributed and affixed edible PUF. The present disclosure generally relates to counterfeit measures, and in particular, to an arrangement concerning an edible unclonable function counterfeit measure.

Abstract: An Anderson localized hyperspectral filter array is disclosed which includes a base layer and a plurality of optical layers deposited on the base layer selected from two or more materials, each material having a refractive index that is different from the other materials of the two or more materials, wherein no consecutively deposited optical layers have the same refractive index, each of the plurality of optical layers having a thickness chosen based on a random number within a predetermined range.
