Embodiment Construction

[0020] In order to further illustrate the technical means adopted by the present invention and the achieved effects, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

[0021] see figure 1 , is a schematic flow chart of the lock screen-based data protection method of the present invention.

[0022] The data protection method based on lock screen of the present invention comprises the following steps:

[0023] S101 acquires the lock screen type selected by the user when setting the lock screen of the smart device;

[0024] S102 Save the acquired lock screen type in a preset storage area in the smart device; wherein, the preset storage area has higher access authority than the general storage area in the smart device;

[0025] S103 When an unlocking operation occurs, determine whether the current lock screen type of the smart device is consistent with the lock...

Abstract

The invention discloses a screen lock based data protection method. The method includes: acquiring a screen lock type which a user selects to screen-lock a smart device; storing the acquired screen lock type in a preset storage area of the smart device; in case of an unlocking operation, judging whether the current screen lock type of the smart device is consistent to the screen lock type stored in the preset storage area; if not, shielding the locking operation. In addition, the invention further discloses a screen lock based data protection device. The screen lock based data protection method and device has the advantages that after a file in which a screen lock password is stored is forcibly deleted or replaced with another file and the screen lock type of the smart device is altered or deleted, the corresponding unlocking operation is shielded, the smart device is effectively avoided being cracked, and data safety is protected.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a lock screen-based data protection method and a lock screen-based data protection device. Background technique [0002] For smart devices, it is very important to effectively protect their own data. Most of the current smart electronic devices are equipped with the function of locking the screen. When the user has an access requirement, the smart device needs to be unlocked first, thereby realizing the information security function of the smart device to a certain extent. Taking a smart phone with an Android system as an example, the purpose of adding a lock screen function is to protect the user's privacy. The lock screen of the smart phone is to encrypt the lock screen password and store it in a certain file under a certain directory of the smart phone, that is, a file for saving the lock screen password. During the unlocking process, the application system of the sm...
