Abstract: The present disclosure relates to information processing systems, methods, devices, and storage mediums. In one example method, a first node stores a private key and public object information, and a second node stores information obtained by encryption based on a public key of the first node. When feature information of an object is not sent out from a client, a plurality of nodes interact with each other based on an information mapping relationship.

Abstract: This application provides a storage device and a data writing method. The storage device may be used in a neural network. The storage device includes a memristor unit, a current-controlled circuit, and a write circuit. The memristor unit has a structure of one-transistor and one-resistive random access memory 1T1R. The current-controlled circuit is configured to limit a current passing through the memristor unit to a target current, where the target current is determined based on target conductance of the memristor unit and a gate voltage of the transistor, and the target conductance is used to indicate target data to be written into the memristor unit. The write circuit is configured to load a write voltage to the memristor unit in cooperation with the current-controlled circuit, to write the target data to the memristor unit.

Abstract: A terminal is disclosed, wherein a metal back cover of the terminal includes a slot. The slot divides the metal back cover into two parts. One of the two parts is used as an antenna radiator. The antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points. The signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded. A distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in an end of the slot.

Abstract: Disclosed are a magnetic memory and a magnetic memory preparation method. The magnetic memory includes a heavy metal layer, a metal film layer, and a magnetic tunnel junction (MTJ) layer. The metal film layer is located between the heavy metal layer and the MTJ layer. A spin-orbit coupling effect of a material of the heavy metal layer is stronger than a spin-orbit coupling effect of a material of the metal film layer.
