Abstract

The disclosure provides a data protection method and device; the method comprises the following steps: receiving a data protection order sent by a server and used for protecting target data, wherein the data protection order at least comprises a target data ID of the target data; determining a target secret key corresponding to the target data according to the target data ID; destroying the target secret key according to the data protection order, thus preventing the target data from being accessed. In the disclosure, the first terminal receives the data protection order sent by the server, and destroys the target secret key; the method and device can fast ensure the target data on the first terminal not to be accessed, thus ensuring user data safety, and improving user data safety protection speed.

Description

technical field [0001] The present disclosure relates to the communication field, in particular to a data protection method and device. Background technique [0002] In related technologies, once a user's terminal, such as a mobile phone, is lost, the security of user data can be ensured by remotely erasing data on the terminal. However, the method of erasing data takes a long time, and an illegal user can terminate the process of erasing data by forcefully restarting the terminal. Therefore, user data security cannot be truly ensured. Contents of the invention [0003] In view of this, the present disclosure provides a data protection method and device to solve the deficiencies in related technologies. [0004] According to the first aspect of the embodiments of the present disclosure, there is provided a data protection method for a first terminal, the method comprising: [0005] receiving a data protection instruction for protecting target data sent by the server, wh...
