Abstract

The embodiment of the invention discloses a data clearing method and device, an electronic device and a storage medium, wherein the method comprises the steps of identifying whether the information ofan identity identification card in a terminal is changed or not; when it is identified that the information of the identity identification card in the terminal is changed, triggering a first timer; when the first timer reaches a preset duration, detecting whether the terminal is in an online state or not; if it is detected that the terminal is in the online state, backing up the user data in theterminal via a cloud and clearing the user data, or else directly clearing the user data. According to the embodiment of the invention, timing is started when the information of the identity identification card is changed, the terminal user data is cleared after the timing is completed, so that the user data can be prevented from being leaked when the terminal is lost.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and in particular to a data clearing method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of mobile terminals, Internet technology has also been rapidly improved. Through the mobile terminal Internet, bank transfers, third-party payments, private information acquisition, etc. can be performed. Once the mobile terminal is lost, the user data will be used by some criminals, which will bring great losses to the user. Contents of the invention [0003] Embodiments of the present application provide a data clearing method, device, electronic device, and storage medium, which can avoid leakage of user data in a terminal. [0004] An embodiment of the present application provides a data clearing method, wherein the data clearing method includes: [0005] Identify whether the identity card information in the identificati...
