Mobile phone antitheft method, device, system and mobile phone

Abstract

The application discloses a mobile phone antitheft method, device, system and a mobile phone. Through the adoption of the application, when a user needs to fetch a user recognition module in the mobile phone, a processor fetches an instruction according to the user recognition module to produce a user recognition module fetching password input prompt information; after receiving the accurate user recognition module fetching password, the processor transmits a fixation relieving instruction to a user recognition module fixing device to relieve the fixation to the user recognition module, so that the user recognition module can be fetched; if the received user recognition fetching password is inaccurate, the processor cannot transmit the fixation relieving instruction to the user recognition module fixing device, the user recognition module fixing device maintains the fixation to the user recognition module, the user cannot fetch the user recognition module so that the user recognition module cannot be fetched at will, the network connection of the mobile phone is maintained, the normal transmission of the positioning information of the mobile phone can be guaranteed, the positioning to the mobile phone is realized, and the probability of finding the mobile phone back.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, in particular to a mobile phone anti-theft method, device, system and mobile phone.
