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.

Provided is an information display medium that can enhance a forgery prevention effect. An information display medium (100) includes a light reflection layer (20) made of a metal or a metallic oxide and partially or fully placed on one surface of a substrate, and the light reflection layer (20) includes a first region (30) where first information is displayed by either of or a combination of an outline shape and a shape of an uneven region, and a second information display region (21a) where identification information formed by partial material removal of the light reflection layer (20), the second information display region being set to partially or fully overlap with the light reflection layer (20) where the first information is displayed in the first region (30).

A management system includes a recording device recording an image of a gaming chip and an inspection device determining a type and authenticity of the gaming chip. The gaming chip has a multilayer structure in which both sides of a colored layer are sandwiched between light color layers, surface printing representing a type of the gaming chip is performed on outer sides of the light color layers, and an authenticity recognition mark is printed on the colored layer of an inside of the light color layers by an infrared absorbing material. A visible light camera photographs a visible light image of the surface printing, and an infrared light camera photographs an infrared image of the internal printing. The inspection device determines the type and authenticity of the gaming chip using the visible light image and the infrared image.

The invention protects a content of a digital or physical document against forgery. It allows automatic detection of any modification in an arrangement of graphical symbols (e.g. a text) provided on a support (e.g. printed or displayed) with respect to an original arrangement by providing on the support reproducible verifiable data including a verification barcode, while eliminating redundancy between data inside the barcode and the graphical symbols, and resolving the problem of the size of the barcode when the size of the data for these graphical symbols is large.

The invention relates to a method for assessing contrasts on surfaces (2), in particular for optically identifying structured and/or pictorial surfaces (2), e.g. of paintings (1) or sculptures, said method being simple to use independently of the location and safe. For this purpose, the method involves the steps of—focusing a camera (5) onto a prominent image dot (3) on the surface, —creating at least two images of a recognizable, high-contrast area of the image dot (3), —storing the image having the greatest depth of detail as a reference image.

A method, system, and computer program product for analyzing images of visual objects, such as currency and/or payment cards, captured on a mobile device. The analysis allows determining the authenticity and/or total amount of value of the currency and/or payment cards. The system may be used to verify the authenticity of hard currency, to count the total amount of the currency captured in one or more images, and to convert the currency using real time monetary exchange rates. The mobile device may be used to verify the identity of a credit card user by analyzing one or more images of the card holder's face and/or card holder's signature, card holder's name on the card, card number, and/or card security code.

The invention relates to a method for recognizing surfaces (2), in particular for optically recognizing or identifying structured and/or pictorial surfaces (2), said method involving the steps of —focusing a camera (5) onto a prominent image dot (3) on the surface (2), —creating at least one live video stream of a recognizable, high-contrast area of the image dot (3), and —guiding the camera (5) to the image frame of the video having the greatest depth of detail by focusing a camera (5) onto a prominent image dot (3) on the surface (2) to be sensed, —creating at least two images of a recognizable, high-contrast area of the image dot (3), —storing the image having the greatest depth of detail as a reference image, —analyzing each image frame of the live video stream, —comparing the image frame having the greatest depth of detail with a target image or reference image.

A medium processing apparatus includes a sensor that is intermittently energized and detects a predetermined physical quantity and outputs the detection value in the energization period, the sensor stabilizing its output after an output stabilization period, which is shorter than the energization period, has lapsed, a storage unit that stores the detection value that has been detected by the sensor before the lapse of the energization period and after the lapse of the output stabilization period, and a controller that reads the detection value from the storage unit and performs a predetermined process by using the detection value read.
