Abstract: A method for automatic switching between access points and a wireless routing device. In the embodiments of the present disclosure, a wireless routing device determines whether an access point device allowing access exists, and if the access point device exists, the wireless routing device establishes a connection to the access point device and disconnects from a terminal.

Abstract: A stride length calibration method includes detecting, by a first device, that a user is walking or running, and collecting a quantity of movement steps of the user. The method further includes determining whether a stride length of the user in a preset database needs to be calibrated. The method further includes requesting to obtain, from a second device, an actual movement distance of the user when calibration is needed. The stride length of the user in the preset database is provided to the first device to calculate a movement distance of the user. The method further includes calculating, by the first device, an actual stride length of the user based on the actual movement distance of the user and the quantity of movement steps of the user. The method further includes updating the stride length of the user in the preset database by using the actual stride length obtained through calculation.

Abstract: Embodiments of the present invention provide a security verification method and a device, and relate to the field of communications technologies, so as to verify a user identity based on a wearing status monitoring result and a pairing result of the device. The method includes: monitoring, by a first device, a pairing status of the first device and a second device and/or a wearing status of the first device; receiving a user operation instruction, where the instruction includes information about an interface operated by a user; when it is determined, based on the information about the interface, that the interface is an access-restricted interface, determining a wearing status and/or a pairing status of the first device within a verification time window; determining, based on the wearing status and/or the pairing status within the verification time window, whether the first device is in a secure state; and locking the interface if the first device is in an insecure state; or responding to the user operation instruction if the first device is in the secure state.
