Abstract
A method for positioning a device includes: sending a query instruction to a server, wherein the query instruction is configured to query a target coordinate location of the terminal device. The method also includes receiving a query response from the server. The query response includes the target coordinate location and a target public key digest. The target coordinate location is obtained by encrypting a coordinate location that is positioned for the device. The target coordinate location is sent to the server as well as the target public key digest synchronously. The method also includes determining a target private key based on the target public key digest; and decrypting the target coordinate location using the target private key to obtain the coordinate location located by the device.
