An authentication apparatus including an input interface to acquires an image of a hologram label on an access object including key information; a processing history storage table that correlates a first image with the key information and stores the correlated image; an information determination circuit that refers to the processing history storage table, based on key information included in a second image that is being acquired after the first image, and determines whether the key information corresponds to key information of the second image; and a processing determination circuit that compares feature data of the second image that is not key information with feature data of the first image that is not key information in response to the information determination circuit determining the key information of the first image as being present, and uses the results of the comparison to determine whether to execute processing using the second image.

A server in communication with a first device capable of receiving input from a camera attached to the first device, and a second device capable of displaying output, is provided. The server is configured to receive, from the first device, data relating to characteristics of the camera and characteristics of an image obtained by the camera of a screen of the second device; determine a screen pixel length of the screen; and provide instructions to the second device to display on the screen an object at a desired visual angle in response to the data received from the second device and the screen pixel length, while the first device is positioned at an arbitrary distance from the screen.

A system and method are described for anonymous IoT device accounts. For example, one embodiment of a system comprises an IoT app to be executed on a mobile device of a user, the IoT app comprising a graphical user interface (GUI) to allow the user to capture one or more identification (ID) codes from one or more IoT devices, the mobile device to transmit the ID codes to an IoT service; a device management module on the IoT service to provision the IoT devices with the IoT service; an account management module on the IoT service to establish an anonymous user account and to associate the anonymous user account with the one or more IoT devices provisioned by the device management module; wherein upon the provisioned IoT devices being associated with the anonymous user account, the GUI of the IoT app is to provide the user with controllable access to the IoT devices prior to the user entering user identification information to the IoT service.

An application for a mobile device, such as a phone, is able to process business card data. A business card can be registered to the application and stored within the application. The individual who registers the information receives identification information, such as simple numerical or verbal sequence, that is able to then be shared with another person who can download the application and enter the identification information into the application. Entering in the identification information will download a person's data from the person's business.

A method for starting an operation process comprises: receiving an operation request message from a terminal device in response to the terminal device scanning a barcode to obtain barcode information and determining an address of the server based on the barcode information, the operation request comprising an image of text associated with the barcode scanned by the terminal device, and the image of text specifying an operation function; determining text content based on the image of text; searching a correspondence relationship between different text content and respective operation access information to obtain operation access information corresponding to the determined text content; and returning the operation access information to the terminal device, for the terminal device to start an operation process by using the operation access information, the operation process having the operation function specified by the received image of text.

The present application provides a barcode-based communication method, including: rendering first transmission information into a first barcode, and displaying the first barcode for scanning by a peer device; and scanning a second barcode displayed by the peer device, to obtain second transmission information included in the second barcode, where the second transmission information is obtained by the peer device based on a processing result of the first transmission information. According to the technical solutions of the present application, two communication parties can perform bidirectional information transmission by using barcodes, to alleviate information asymmetry caused by unidirectional communication and improve service integrity and security.

A method for determining an operating state of a machine includes measuring a signal of the machine, applying the measured signal to a machine-learned classifier or machine learning model learned on machine signals and associated operating states, generating the operating state of the machine based on the application of the measured signal to the machine-learned classifier or machine learning model, and outputting the operating state of the machine.
