Abstract

The present invention relates to the technical field of data security, and discloses an anti-theft method for terminal data. In the present invention, the method comprises the following steps: if a user identification card being removed is detected, a terminal entering a timing protection status with preset duration; in the duration of the timing protection status, if a correct unlock password is received by the terminal, the terminal exiting the timing protection status; and when the timing protection status ends, the terminal performing a data protection command. With respect to the prior art, the method disclosed by the present invention can protect the terminal data from being illegally stolen in case of no network, thereby greatly enhancing the security of the terminal data.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to an anti-theft method for terminal data. Background technique [0002] With the rapid popularization of smart phones and the great improvement of smart phone application performance, smart phones are comparable to a small mobile database, storing a large amount of information. This information is likely to be related to the user's business secrets and personal privacy. Therefore, the data security of smart phones is very important and has become the focus of competition among major mobile phone manufacturers. [0003] Password protection is a common data security protection method, but the security of this method alone is low. Once the password is cracked, user data can be illegally stolen. Alternatively, when the mobile phone is unlocked, data protection can be realized by automatically deleting the mobile phone data when the number of wrong password input times exceeds th...
