Method for determining whether electronic device needs to be re-authenticated, and electronic device

A method, comprising:

• scanning and storing, by an electronic device, wireless signals generated by at least one device in a surrounding environment;
• determining, by the electronic device based on one or more wireless signals obtained during first n times of scanning, a corresponding occurrence probability of each wireless signal of the one or more wireless signals during the first n times of scanning, wherein n is an integer greater than 1;
• determining, by the electronic device based on a wireless signal obtained during an (n+1)th time of scanning and the corresponding occurrence probability of the each wireless signal during the first n times of scanning, a confidence level of the wireless signal obtained during the (n+1)th time of scanning;
• and
• determining, by the electronic device based on the confidence level of the wireless signal obtained during the (n+1)th time of scanning, whether the electronic device needs to be re-authenticated.

An electronic device, comprising:

• at least one processor and a memory, wherein the at least one processor is coupled to the memory, the memory stores program instructions that, when the program instructions stored in the memory are executed by the at least one processor, cause the electronic device to perform operations including:
• scanning and storing wireless signals generated by at least one device in a surrounding environment;
• determining, based on one or more wireless signals obtained during first n times of scanning, a corresponding occurrence probability of each wireless signal of the one or more wireless signals during the first n times of scanning, wherein n is an integer greater than 1;
• determining, based on a wireless signal obtained during an (n+1)th time of scanning and the corresponding occurrence probability of the each wireless signal during the first n times of scanning, a confidence level of the wireless signal obtained during the (n+1)th time of scanning;
• and
• determining, based on the confidence level of the wireless signal obtained during the (n+1)th time of scanning, whether the electronic device needs to be re-authenticated.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, the computer program comprises program instructions that, when the program instructions are executed by an electronic device, cause the electronic device to perform operations including:

• scanning and storing wireless signals generated by at least one device in a surrounding environment;
• determining, based on one or more wireless signals obtained during first n times of scanning, a corresponding occurrence probability of each wireless signal of the one or more wireless signals during the first n times of scanning, wherein n is an integer greater than 1;
• determining, based on a wireless signal obtained during an (n+1)th time of scanning and the corresponding occurrence probability of the each wireless signal during the first n times of scanning, a confidence level of the wireless signal obtained during the (n+1)th time of scanning;
• and
• determining, based on the confidence level of the wireless signal obtained during the (n+1)th time of scanning, whether the electronic device needs to be re-authenticated.

A chip, comprising:

• a processor, configured to invoke a computer program from a memory and run the computer program, so that an electronic n device on which the chip is installed performs operations including:
• scanning and storing wireless signals generated by at least one device in a surrounding environment;
• determining, based on one or more wireless signals obtained during first n times of scanning, a corresponding occurrence probability of each wireless signal of the one or more wireless signals during the first n times of scanning, wherein n is an integer greater than 1;
• determining, based on a wireless signal obtained during an (n+1)th time of scanning and the corresponding occurrence probability of the each wireless signal during the first n times of scanning, a confidence level of the wireless signal obtained during the (n+1)th time of scanning;
• and
• determining, based on the confidence level of the wireless signal obtained during the (n+1)th time of scanning, whether the electronic device needs to be re-authenticated.
