A system contributing to prevention of unauthorized use of an information code displayed on a screen. In the system, an information code display device cyclically displays a plurality of partial code images on a display screen of a display unit based on a first rule when the first rule is received from a server in response to a first request to the server. Accordingly, an information code reading device captures images of the display screen at imaging intervals according to a second rule which is received from the server by in response to a second request to the server to decode an information code composed of the plurality of images thus captured, according to the second rule.

A system and method that enables users to provide authenticated medical records (e.g., vaccination records, viral anti-body test results, etc.) to a third-party (e.g., a venue) to gain access to the third-party is provided. In this way, the third party may confirm that the user is sufficiently immune to a particular disease (e.g., COVID-19) and may thereby minimize the threat of the user introducing the contagious disease to the third party. The system includes a biometric data recognition system that authenticates the identity of a user, a medical records acquisition system that acquires the medical records of the authenticated user, and a system for the displaying or otherwise providing the medical records to the third-party for review. The system also includes a system identification card that includes the user's contact information, alphanumeric characters associated with the user's driver's license number, medical records of the user, and other elements.

Various implementations disclosed herein include devices, systems, and methods for verifying that an image includes a complete code of a time-varying visual marker that displays codes sequentially on a display. In some implementations, the verification determines that the image include a complete code rather than combinations of sequentially-displayed codes that may be included in an image based on use of a rolling shutter (e.g., in a camera of a detecting electronic device). In some implementations, the verification involves comparing a first verification portion of an image to a second opposing verification portion of an image. Various implementations disclosed herein include devices, systems, and methods for modifying image capture parameters (e.g., frame rate) to ensure capture of all codes of a time-varying visual marker.

A value is exchanged between accounts held by users of two portable electronic devices. The devices synchronize disappearance of the image at the sending device and appearance of the image at the receiving device to give the impression that a physical object representative of the value has been exchanged (e.g., handed) between the users.

The present invention relates to the technical field of televisions, and provides a method for processing a television screenshot, a smart television, and a storage medium. To meet the demands of a more intuitive user interface and a seamless user interaction function, multiple sets of optional bars are displayed while displaying current playback content on a display screen in response to an input screenshot operation instruction, wherein optional bars are respectively used for displaying a picture thumbnail of a screenshot, recognizing content-related recommended content on the basis of an image of the screenshot, and/or responding to a user control instruction input interface for an operation associated with the screenshot.

Systems and methods for securely generating and printing documents are disclosed. For example, processor(s) of a computer system may receive information for the document from a computing device through a network, verify the information for the document, and upon verification, generate document generation data using at least a portion of the information for the document. The document generation data may include document metadata that enables generation of an image of the document and/or the image of the document. Upon the processor(s) verifying first authentication information of a first code associated with a printing device received from the computing device through the network and second authentication information of a second code associated with the computing device received from the printing device through the network, the processor(s) may transmit the document generation data to the printing device through the network, and cause the printing device to print the image of the document.

A collation device includes a light source unit; a camera unit that receives light emitted from the light source unit and reflected in a collation area of an object to acquire a photographed image of the collation area; and a processor configured to, by executing a program: detect a positional relationship between the light source unit and the camera unit by using the photographed image, and notify of a collation result between the photographed image and a registered image prepared in advance by using the positional relationship.

A system and method for generating and implementing a barcode is provided, wherein the system includes a data generation device configured to receive data and generate barcode data response to the received data, a barcode generation device, configured to receive the barcode data and generate a barcode responsive to the received barcode data, a display device, configured to display the barcode and a barcode receiving device, configured to receive the barcode and operate in response to the barcode.

A light emitting apparatus recognition system includes a light emitting apparatus, an image capturing apparatus, a recognition apparatus, and an electromagnetic wave emitting element. The light emitting apparatus includes a light source that blinks on the basis of identification information unique to the light emitting apparatus and an electromagnetic wave receiving element. The image capturing apparatus captures an image of light emitted by the light source of the light emitting apparatus. The recognition apparatus recognizes the light emitting apparatus on the basis of the light appearing in the image captured by the image capturing apparatus. The electromagnetic wave emitting element emits an electromagnetic wave from the image capturing apparatus or a vicinity of the image capturing apparatus. The electromagnetic wave receiving element receives the electromagnetic wave emitted by the electromagnetic wave emitting element.

An automated system/method for identifying and enabling viewer selection/purchase of products or services associated with digital content presented on a display device. Products within the digital content are identified and existing product placement data is ascertained. For products that do not include such data, other methodologies, with the assistance of third-party servers, are employed to assess identity and purchase availability. Viewer input designate products to assess or products can be automatically assessed. Viewers initiate purchase of identified products via the display device or other electronic devices controlled by viewers, such as via viewers' smart phones. Various processes for identifying products include use of AI processing, access to data on third-party servers, crowd sourcing and other methodologies. Various techniques for selecting products for purchases are employed including employing 3D codes (e.g., QR codes) alongside presented products to enable other portable electronic devices to facilitate purchase. Other features are described.
