Abstract

The invention provides a data encryption method and device, and a terminal. The method can comprise the following steps: when a decryption operation of enabling a terminal decryption function is detected, obtaining an unlocking password used by the decryption operation; generating a first key based on the unlocking password; and when the first key is consistent with a pre-stored second key, decrypting encrypted data stored on the terminal based on the first key, wherein the second key is generated based on a lock screen password set by a legal user. By application of the data encryption method and device provided by the embodiment of the invention, the encrypted data on the terminal are decrypted without losing any data, therefore the data security of the terminal is improved, convenience is provided for the user and the user experience is optimized.

Description

technical field [0001] The present disclosure relates to the technical field of terminal data security, and in particular, to a data decryption method, device and terminal. Background technique [0002] In related technologies, devices using the Android system, such as terminals, all support the function of encrypting data in the data partition, but do not provide a method for decrypting the data in the data partition. Once the user encrypts a terminal such as a mobile phone, if he no longer wants to use the encryption function, or forgets the encryption password, he can only reset the mobile phone and reformat the data partition of the mobile phone to delete the password and enter the system. The conversion process will lead to loss of data in the terminal, causing certain losses to the user, and the user experience is not good. Contents of the invention [0003] The present disclosure provides a data decryption method, device and terminal to overcome the defect in the r...
