Abstract: An Internet of Things system, an authentication and communication method therefor, and a related device. The Internet of Things system comprises: an Internet of Things terminal, configured to establish a connection with a proxy server by using a connection certificate of the Internet of Things terminal, and send device information and an authentication identifier of the Internet of Things terminal to the proxy server; the proxy server, configured to receive the device information and the authentication identifier, and send the device information and the authentication identifier to an Internet of Things platform; and the Internet of Things platform, configured to receive the device information and the authentication identifier, perform identity verification on the Internet of Things terminal according to the device information and the authentication identifier, and in response to the fact that the verification passes, return a verification success message to the proxy server.

Abstract: The present disclosure provides a data synchronization method including: acquiring positioning information of a target object in a target space scene; mapping the positioning information to obtain number data corresponding to the positioning information, wherein a data amount of the number data is less than that of the positioning information; and sending the number data to a server so that the server sends the number data to other client. The technical scheme according to the embodiment of the present disclosure can effectively decrease the data amount in the data synchronization process and the bandwidth pressure.

Abstract: The present disclosure provides an anti-counterfeiting verifying method, a hardware apparatus, a system, an electronic device and a storage medium, which aim at improving anti-counterfeiting effectiveness for the electronic products, the method includes: executing a step of generating to-be-verified information of the first device in response to a triggered verification event; outputting the to-be-verified information to indicate a second device to send the to-be-verified information to a verifying terminal, the verifying terminal being configured to for verifying authenticity of the first device according to the to-be-verified information, and feeding back a verification result to the first device and/or the second device for displaying, wherein the step of generating the to-be-verified information of the first device includes: obtaining a device identifier of the first device and a private key pre-stored in the first device.

Abstract: A data visualization method is disclosed, including receiving business data and classifying the business data according to a business type associated with the business data so as to form multiple sets of target data, processing at least one set of the multiple sets of target data to obtain update data for an interactive interface, the interactive interface corresponding to the business type of the at least one set of target data and configured to display the at least one set of target data; rendering the interactive interface based on the update data to update content of the interactive interface. Thereby, isolation of data of different business types and linkage of data of the same business type are achieved, which improves the efficiency of visualized presentation of data.

Abstract: Park monitoring methods, park monitoring systems, and computer-readable storage media are provided. A method includes: determining a first path from a current position of a first object to a first position; generating a 3D virtual image of a surrounding environment when the first object is moving along the first path based on a perspective of the first object; and when the first object is located at the first position, displaying a real image of the first position.
