Abstract: Embodiments relate to a non-fungible physical (NFP) item. The non-fungible physical (NFP) item comprises an identifier. The identifier is embedded and layered within the non-fungible physical item in an unplanned pattern. The identifier in the unplanned pattern is configured to provide high security against counterfeiting of the non-fungible physical (NFP) item. The identifier comprises at least one of a random marker and a unique marker. The unplanned pattern comprises at least one of a random pattern and a unique pattern. Further the non-fungible physical (NFP) item is registered as a non-fungible token on a blockchain. The NFP item is then paired with the non-fungible token for enabling two-way mutual authentication and enhanced authenticity. The pairing of the NFP item with the non-fungible token enables tracking condition, provenance, and grading of the NFP item.

Abstract: In a banknote inspection device, a storage unit stores a first learning model generated using an image of a character with a hole as training data, and a second learning model generated using an image of a character without a hole as training data, and a recognition unit recognizes a serial number character that is a character forming a serial number of a banknote by using the first learning model when a character image, which is as image of the serial number character, has a hole, and recognize the serial number character by using the second learning model when the character image does not have a hole.

Abstract: A plasmonic structure having an identifier pattern indicating a genuine product for preventing counterfeiting, falsification or reuse, includes a metal layer; a photoconversion pattern layer including a plurality of photoconverting nanoparticles disposed in a pattern on and in direct contact with the metal layer; a metal pattern layer including a plurality of metal particles disposed in a pattern on and in direct contact with the photoconversion pattern layer; and an adhesive film disposed on the metal pattern layer. An identifier pattern indicating a genuine product is easily identified even by visual inspection after irradiation with infrared light irradiation. The plasmonic structure is fundamentally impossible to re-assemble after deformation of the plasmonic structure caused by disassembly of a product or packaging container, thereby preventing counterfeiting, falsification or reuse.

Abstract: A method for creating a secure document, registering the secure document and verifying the authenticity of the secure document includes receiving a print object that has content. A security feature, including an identifier, is created and is associated with the content. The identifier may be a barcode. The barcode may represent a character string. The security feature may include the identifier barcode and a decoy barcode that is not associated with the content. The identifier barcode (or the character string represented by the barcode) and the content are transmitted to a database for storage. Once stored, the identifier and the content are considered to be registered. A print object that includes the security feature and the content is then transmitted to a printer for printing.

Abstract: A method for automated authentication of a security label comprises capturing a first image of the security label under a first lighting condition and capturing at least a second image of the security label under a second lighting condition. Further, the first image and the second image are verified to check whether the first image and the second image meet pre-defined expectation under the first lighting condition and the second lighting condition respectively. Authenticity of the security label is confirmed by the processor if the expectation is met.

Abstract: An apparatus and method for checking value documents, in particular bank notes, and a value document processing system having at least one sensor for capturing an electromagnetic radiation transmitted by a value document and generating corresponding transmission signals, and an evaluation device for checking whether the value document has a foreign object taking into account the transmission signals. From the transmission signals an edge course of the value document is derived and a rectangle is approximated to the edge course. By comparing the edge course of the transmission image with the rectangle, the presence of a foreign object such as an adhesive tape, can be ascertained.

Abstract: A method and apparatus for establishing product items unique identity for purpose of anti-counterfeiting or anti-theft is disclosed. It employs a fluorescent taggant embedded in product item, template, digitally based Encoder and Decoder. The taggant comprising plurality of fluorescent entities which in turn may comprise such distinct geometric and spectral optical characteristics-attributes as relative locations, emission/absorption spectra, polarization degrees and post luminanc delay and duration times. Such uniqueness is determined by the presence of a combination of a wide variety of fluorescent materials used during the application. The set of fluorescent entities are result of a random process and form a product item's fingerprint. The said template is a particular digitized representation of a taggant. The Encoder may comprise a camera, LED array based activator, configured to follow a particular illumination sequence and computation unit. The said camera further comprises at least two polarizing filters and template generator and the respective controllers. The Decoder may comprise at least one camera identical to the of the Encoder, at least one template/taggant readers and a computation unit, which may be shared with the said Encoder. Product item identity is based on the fluorescent taggant uniqueness, with the later embedded into the product in a non separable way. After the extracted attribute values assiciated with the taggant, are digitized. Digitazing comprises mixing with chaff (spurious) patterns of the same format, error correction, transformation in a non invertible and compression and encryption. This forms a template, embedded in the product in a readable form. The decoding comprises feature extraction of taggant, reading template and decrypting, its content, error correction, decompression. Then the extracted and the decoding results are cross-matched in order to identify the product item. Irreproducibility of a plurality of fluorescent entities and high degree of security of its digital representation due to encryption, high variability of LED patterns and non-invertible transformation is a basis of a chaosmetric anti-counterfeiting solution disclosed in the present invention.

Abstract: Provided are an information recording object and a reading device devised so that embedded information is difficult to guess. The information recording object 30 provided with a combined image comprising an image C1 printed in a lustrous layer 31 and an image C2 formed on the image C1 and printed in a transparent layer 32 is characterized in that: the image C1 and the image C2 are each printed with an ink for which the amount of reflected light differs according to viewing angle; for the combined image, one image is visible depending on the viewing angle; the image C2 is an image in which there is a regularity in feature points in a spatial frequency domain F2; and the image C1 is an image in which the feature points in a spatial frequency domain F1 are disposed at positions that block said regularity.
