A smart quarantine system includes an artificial intelligence control system which receives information about an emigration and immigration person, stores at least a portion of the information about the emigration and immigration person, compare the at least a portion of the information about the emigration and immigration person with pre-stored information, and create a complete barcode based on the comparison result, a symptom identification unit to identify a normal or abnormal health state of the emigration and immigration person, based on the complete barcode, and a quarantine execution unit to execute customized quarantine based on the normal or abnormal health state of the emigration and immigration person. The quarantine execution unit includes: an isolation and examination recommendation unit to recommend isolation and examination such that the emigration and immigration person is isolated and examined, when a health state of the emigration and immigration person is abnormal, an immigration approval unit to approve immigration of the emigration and immigration person when the health state of the emigration and immigration person is normal, and a self-diagnosis system to perform self-diagnosis of a health of the emigration and immigration person after the immigration.

A system and method for recognizing a person, including: capturing an identifying feature of the person; identifying the person based on the identifying feature to return a person identity; using the person's identity, retrieving information about the person from a person information database; and displaying the retrieved information in an overlay with a facial image of the person to a user. menu items can also be displayed. The identifying feature may be a biometric or a non-biometric feature.

Photographed image acquisition means (201) of an information processing device (20) acquires a photographed image photographed by photographing means (25) capable of photographing a target image including predetermined information. Reference means (202) refers to storage means (200) for storing the target image photographed in the past and information extracted from the target image in the past, in association with each other. Determination means (207) determines whether or not the target image photographed in the past has been captured in the photographed image. Processing execution means (211) executes, when the target image photographed in the past has been captured in the photographed image, predetermined processing based on the information associated with the target image.

The present application provides a method and system for providing and verifying a two-dimensional code. During operation, the system receives, from a terminal of a first user, a two-dimensional code generation request comprising service data, which comprises at least an identifier of the first user. The system obtains a picture that is identifiable by naked eyes, associates the obtained picture with the identifier of the first user, and stores the association between the obtained picture and the identifier of the first user. The system generates a two-dimensional code based on the service data or based on a combination of the service data and the obtained picture and provides the two-dimensional code and the obtained picture to the first user, thereby facilitating the first user to display the two-dimensional code and the obtained picture when providing services.

A stealth white ink contains a red coloring material that emits visible light at exposure to ultraviolet radiation, a green coloring material that emits visible light at exposure to ultraviolet radiation, and a blue coloring material that emits visible light at exposure to ultraviolet radiation, wherein a dry film of the stealth white ink has an a* value of from −2.0 to 2.0 and a b* of from −10.0 to 0 at exposure to ultraviolet radiation having a wavelength of 370 nm according to CIE 1976 L*a*b* colorimetric system.

A device communicates with a scanner, such as a barcode scanner in a retail environment, and with a point-of-sale (POS) register. The device can process different types of machine-readable codes, such as scanned UPCs and unique barcodes associated with individual scratcher cards and/or other items. Data captured by the scanner passes through the device before reaching the POS register; such data may be selectively retransmitted (with or without modification) to the POS register and/or to a server or other device, or it may be blocked from reaching the POS register, server, and/or other device, depending on the current mode of operation. For example, the device can selectively relay some information (such as UPC data) to the POS register to process sales transactions, and/or can relay other information (such as unique barcode data) to server(s) to perform inventory tracking functions, while blocking such unique barcode data from reaching the POS register.

A system and method are disclosed for creating 2D barcodes that are watermarked in a digital fashion. The system and method include changing specific elements within the code words as well as modifying the physical representation within elements of the codewords.

The presently disclosed subject matter is directed to compositions of machine verifiable marks comprising embedded unique identifiers and error correction features. In one embodiment, a composition includes an ordered arrangement of reference characters selected from among a plurality of reference characters. Each reference character of the plurality of reference characters is distinct based upon a value calculated by a similarity of one shape to another. The composition further includes a numeric equivalent associated with the reference characters and an error correction feature.

This marking system is provided with: a marking device which has a marking unit which gives a mark for managing the quality of a product, a housing part which houses one or more temperature indicating materials, and a providing unit which provides, to the marking unit, a temperature indicating material selected by the housing part; and a control device which has a storage unit that stores temperature-indicating material information on a developing temperature or/and a decoloring temperature of each of the temperature-indicating materials included in the housing part; and a processing unit that acquires, from a server or an input unit, an appropriate temperature of the product, selects, on the basis of the acquired appropriate temperature of the product and the temperature-indicating material information, a temperature-indicating material, and notifies the providing unit of details of providing the selected temperature-indicating material.

In some examples, an article includes a substrate having a surface; a parent optical element set comprising one or more parent optical elements disposed on the surface of the substrate, a child optical element set comprising one or more child optical elements disposed on the surface of the substrate. Each of the parent optical elements has a first retroreflective property and each of the child optical elements has a second retroreflective property different from the first retroreflective property.
