A system for remote identification of users. The system uses deep learning techniques for authenticating a user from an identification document, using automated verification of identification documents and detection that a live person identified by the document is present. Liveness of a user indicated by the identification document may be determined with a deep learning model trained for identification of facial spoofing attacks. The deep learning model may be trained using training data extracted from facial feature locations of training images.

A security transfer element includes a security element layer composite with a functional layer arranged to develop an optically variable effect for a viewer. On the opposite side of the functional layer with respect to the viewer, the security element layer composite has at least one luminescent substance. The luminescent substance has a primary emission wavelength and can be excited by an excitation radiation. The functional layer is configured to be opaque to the emission radiation of the luminescent substance. The security transfer element comprises a carrier film, and the security element layer composite is arranged on the carrier film in a detachable manner. The security element layer composite comprises a functional layer and an adhesive layer. The functional layer has an embossing lacquer with an embossed structure. The embossing lacquer is coated with a metallization. The adhesive layer comprises several luminescent substances.

An identification device according to the present invention that performs authenticity determination of an article provided with an anti-counterfeiting medium whose observed light pattern changes depending on an observation angle includes a similarity calculating unit that calculates a degree of similarity between captured image data of the anti-counterfeiting medium and reference image data; an authenticity determination unit that performs authenticity determination as to whether the anti-counterfeiting medium is genuine or not on the basis of whether the degree of similarity exceeds a predetermined threshold or not; and a match-percentage notification unit that notifies a match-percentage indicative of a degree of match between an imaging viewpoint for imaging the anti-counterfeiting medium and a reference imaging viewpoint which is predefined as the imaging viewpoint for the captured image data used for authenticity determination.

A device for producing a master diffraction grating includes a light source unit and a reflecting member 11. The light source unit forms a first interference fringe by irradiating a substrate surface of a master substrate 101 with light. The reflecting member 11 reflects the light from the light source unit reflected on the substrate surface of the master substrate 101 and guides the light again to the substrate surface side to form a second interference fringe. A resist pattern based on the first interference fringe and the second interference fringe is formed on the substrate surface of the master substrate 101.

An identification device includes, an imaging condition determinator configured to determine an imaging condition as to whether or not an optical change in the anti-counterfeit medium is imageable from an observation angle that is an angle of captured image data in an imaging direction with respect to a reference line on an observation object surface of the anti-counterfeit medium being designed such that an observed pattern of light varies as the observation angle varies, a similarity calculator configured to obtain similarity between the captured image data and correct image data generated from the optical change corresponding to the observation angle when it is determined that the optical change is imageable under the imaging condition; and an authenticity determinator configured to perform authenticity determination as to whether or not the anti-counterfeit medium is correct based on whether or not the similarity exceeds a preset similarity threshold.

A system includes a plurality of optical identifiers and a reader for the optical identifiers. Each optical identifier has an optical substrate and a volume hologram (e.g., with unique data, such as a code page) in the optical substrate. The reader for the optical identifiers includes a laser, and a camera. The laser is configured to direct laser light into a selected one of the optical identifiers that has been placed into the reader to produce an image of the associated volume holograms at the camera. The camera is configured to capture the image. The captured image may be stored in a digital format by the system.

A hologram that includes a formation layer and a reflection layer that are laminated. The formation layer has an optical phase modulation structure on a first interface in contact with the reflection layer. When reference light emitted from a point light source enters through a second interface different from the first interface of the formation layer, the entirety or part of an image to be reconstructed by the optical phase modulation structure is reconstructed as spatial information on the point light source side relative to the second interface.

In one aspect, the present disclosure relates to a computer-implemented method for virtual deposit of paper currency. In some embodiments, the method may include receiving an indication from a device of a virtual deposit of paper currency to an account; receiving an image of the paper currency from the device; determining whether a virtual-deposit irregularity has occurred; in response to determining whether the virtual-deposit irregularity has occurred, crediting the account with at least a portion of the value of the virtually deposited paper currency; and providing a notification of a time period for physical deposit of the paper currency.

A system and a method for verifying authenticity of a physical copy and a digital copy of a document are disclosed. The method comprises registering a document in a repository by storing details related to the document in a location of the repository. A symbology for the document is generated. The symbology is an identifier of the location of the repository comprising the document. The symbology is associated with either a physical or a digital copy of the document. The digital copy of the document is printed to generate a printed copy. The printed copy or the physical copy of the document is scanned to generate a scanned image. The document and the details related to the document present at the location of the repository are accessed. The scanned image is compared with the document stored in the repository to determine the authenticity of either the physical copy or the digital copy of the document.

A user is guided to move a device equipped with an illuminator and a camera with respect to a document whose genuineness is to be assessed. The motion includes changing the distance between the device and the document by moving the device or moving the document. Imagery of the document is captured during the movement and analyzed to determine a likelihood that the document includes features indicative of genuineness, such as a hologram, an original photograph, and other regions matching those of a genuine document. The analysis may include identifying regions exhibiting large changes in appearance over relatively small distance changes which characterize holograms, and obtaining the spatial extent of document features.
