In order to efficiently acquire an optical characteristic from partial areas on the paper sheet, a paper sheet recognition apparatus (1) that recognizes a paper sheet by using an optical spectrum acquired from the paper sheet on a transport path (60) includes, a light source unit (31) including light sources arranged corresponding to the partial areas on the paper sheet, a reading unit (32) having a light receiving surface to receive reflected lights from the partial areas, a sensor unit (34) that acquires an optical spectrum from light received by the light receiving surface, a memory (80) that stores an optical spectrum measurement condition for acquiring an optical spectrum from a predetermined partial area on the paper sheet. The optical spectrum measurement condition includes information for identifying at least one light source corresponding to the predetermined partial area among the light sources of the light source unit (31), information for identifying a timing for turning on the identified light source, and information for identifying a timing for turning off the light source turned on at the timing for turning on; and a light-source control unit (72) that controls the light source unit (31) based on the optical spectrum measurement condition.

To provide an authentication device and method for a security medium including a reflective volume hologram, capable of easily performing authentication determination and a security medium including the reflective volume hologram.

An authenticity determination device 1 for a security medium 10 including a reflective volume hologram 2 includes a light source L disposed on the front surface side of the reflective volume hologram 2 so that light emitted therefrom is incident on the reflective volume hologram 2, a first observation device 11 disposed in a pre-designed diffraction direction of the reflective volume hologram 2, and a second observation device 12 disposed in a direction other than the pre-designed diffraction direction of the reflective volume hologram 2. Light including a pre-designed diffraction wavelength is emitted from the light source L to be incident on the reflective volume hologram 2, and at this time, when the light amount observed in the first observation device 11 is larger in the diffraction wavelength than in other wavelengths, and the light amount observed in the second observation device 12 is smaller in the diffraction wavelength than in other wavelengths, it is determined that the reflective volume hologram 2 is genuine.

An image captured for a currency note is preprocessed to correct pixel intensity values to expected pixel intensity values. The corrected image is passed to a currency validator for determining whether the currency not is genuine or non-genuine.

The disclosure relates generally to checks and other negotiable financial instruments and particularly to mitigating exposure to financial fraud. Specifically, the disclosure relates to systems and methods of authenticating checks issued by a first entity for the benefit of a third party.

A wirelessly powered display comprises a substrate, an antenna with multiple turns disposed on the substrate, an electronic circuit disposed on the substrate, and one or more pixels each having one or more inorganic light-emitting diodes disposed on the substrate. The electronic circuit is electrically connected to the one or more inorganic LEDs and the antenna, the antenna is responsive to electromagnetic energy to provide electrical power, and the electronic circuit includes a power converter that converts a signal with a relatively high current and low voltage to a signal with a relatively high voltage and low current. A wirelessly coupled display system includes a device including a wireless power transmitter that provides wireless power within a specified range and one or more wirelessly powered displays located within the range and responsive to the wireless power provided by the device to display an image.

A hybrid high-security document includes a document and one or more independent light-emitting modules disposed on or embedded in the document. Each module comprises an antenna with multiple turns, an electronic circuit, and a light emitter mounted and electrically connected on a substrate separate from the document. The electronic circuit is responsive to electrical power provided from the antenna to control the light emitter to emit light. The electronic circuit can include a memory storing information relevant to the hybrid high-security document or its use. The information can be accessed by external readers providing electromagnetic energy to the hybrid high-security document. The hybrid high-security document can be a hybrid banknote.

A system for remote identification of users. The system uses deep learning techniques for authenticating a user from an identification document and using automated verification of identification documents. Identification documents may be authenticated by validating security features. The system may determine features expected in a valid identification document and determine whether those features are present, employing techniques, such as determining whether direction-sensitive features are 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.

Existing currency validation (CVAL) devices, systems, and methods are too slow, costly, intrusive, and/or bulky to be routinely used in common transaction locations (e.g., at checkout, at an automatic teller machine, etc.). Presented herein are devices, systems, and methods to facilitate optical validation of documents, merchandise, or currency at common transaction locations and to do so in an obtrusive and convenient way. More specifically, the present invention embraces a validation device that may be used alone or integrated within a larger system (e.g., point of sale system, kiosk, etc.). The present invention also embraces methods for currency validation using the validation device, as well as methods for improving the quality and consistency of data captured by the validation device for validation.
