摘要： A device authentication method, a service access control method, a device, and a non-transitory computer-readable recording medium are provided. In the device authentication method, an authentication request device issues an authentication request transaction in a distributed ledger, and an authentication response device reads the authentication request transaction in the distributed ledger and performs authentication. Thus, no third-party authentication center or coordinate device is required to participate in an authentication handshake process, thereby reducing deployment overhead of an authentication system and improving efficiency of authentication and access service control.

摘要： An area restricted access system, method, and non-transitory computer-readable storage medium are provided. The system includes an access device and a first service device located in a service area, wherein the access device locates a user device via a first type of wireless signals and obtains a first location parameter. The first service device monitors and locates the user device via a second type of wireless signals and obtains a second location parameter. The area restricted access system generates a modified location parameter based on the first and the second location parameters and determines whether the user device is within or out of the service area based on the modified location parameter. The first service device allows the user device to access the first service device when the user device is within the service area, and forbids the user device to access the first service device when the user device is out of the service area.

摘要： A method, an apparatus and an electronic device for processing a panoramic image are provided. The method includes converting a first planar projection image of the panoramic image into a spherical image; determining a position of a region of interest in the spherical image; and cutting and expanding the spherical image based on the position of the region of interest in the spherical image, and obtaining a second planar projection image of the panoramic image. A distance between the region of interest in the second planar projection image and a center point of the second planar projection image is shorter than a distance between the region of interest in the first planar projection image and a center point of the first planar projection image.
