Abstract
Disclosed in the present invention is a contact tracing pre-screening method for infectious disease susceptible people based on WiFi matching. In the method, based on WiFi connection records of a user and a list of anonymous identification codes of confirmed users collected by a mobile device, a judgment on whether a user has an infection risk is given through the steps of record matching, information compression, dangerous WiFi database construction, coincidence rate calculation between the user and a dangerous WiFi, etc. Data required by this method is easy to be obtained for general smart mobile devices, and no special application program is required. Compared with traditional contact tracing methods based on GPS and Bluetooth, this method provides another dimension of information without using an additional device and sensitive data, has higher operating efficiency, and can help to carry out contact tracing more comprehensively and efficiently.
