Method for positioning terminal device, electronic device and storage medium

A method for positioning a terminal device, for a second terminal device, comprising:

• sending a target public key digest matching a positioning period to a server in response to reaching the positioning period;
• receiving a target public key from the server and verifying the target public key based on the target public key digest;
• encrypting a coordinate location positioned by the second terminal device using the target public key to obtain a target coordinate location in response to the target public key passing verification based on the target public key digest;
• and
• sending synchronously the target public key digest and the target coordinate location to the server.

An electronic device, comprising:

• a processor;
• a memory, connected communicatively to the processor, and storing machine readable instructions that, when executed by the processor, cause the processor to:
• send a query instruction to a server, wherein the query instruction is configured to query a target coordinate location of a terminal device to be found;
• receive a query response from the server, wherein:
• the query response comprises the target coordinate location and a target public key digest,
• the target coordinate location comprises a coordinate location encrypted using a target public key in response to the target public key passing verification based on the target public key digest, and
• the coordinate location is obtained by locating the terminal device to be found;
• determine a target private key based on the target public key digest;
• and
• decrypt the target coordinate location using the target private key to obtain the coordinate location located by the terminal device to be found.
