Abstract

Implementations of data security technologies are disclosed. In an implementation, a plurality of feature points of a user-selected image are determined. A first plurality of interactive operations performed on at least a portion of the plurality of feature points by a user are detected during lock screen passcode set up of a mobile computing device. The first plurality of interactive operations are stored. The user-selected image is displayed on a lock screen when the mobile computing device is in a locked state. A second plurality of interactive operations on a touchscreen of the mobile computing device are detected when the mobile computing device is in the locked state, and the mobile computing device is unlocked if the second plurality of interactive operations match the first plurality of interactive operations.

First claim

What is claimed is:

1 . A computer-implemented method, comprising:
determining a plurality of feature points of a user-selected image; detecting a first plurality of interactive operations performed on at least a portion of the plurality of feature points by a user during lock screen passcode set up of a mobile computing device; storing the first plurality of interactive operations; displaying the user-selected image on a lock screen when the mobile computing device is in a locked state; detecting a second plurality of interactive operations on a touchscreen of the mobile computing device when the mobile computing device is in the locked state; and unlocking the mobile computing device if the second plurality of interactive operations match the first plurality of interactive operations.

2 . The computer-implemented method of claim 1 , further comprising receiving an image from a camera of the mobile computing device before determining the plurality of feature points.

3 . The computer-implemented method of claim 1 , wherein the plurality of feature points of the image are determined by at least one of the mobile computing device or one or more selections made by the user.

4 . The computer-implemented method of claim 1 , wherein the first plurality of interactive operations and the second plurality of interactive operations are at least one of a plurality of strokes that connect at least a portion of the plurality of feature points to form a pattern or a plurality of tapping operations on at least a portion of the plurality of feature points.

5 . The computer-implemented method of claim 1 , wherein displaying the user-selected image on the lock screen further comprises displaying the plurality of the feature points superimposed on the user-selected image.

6 . The computer-implemented method of claim 1 , wherein the second plurality of interactive operations match the first plurality of interactive operations when the interactive operations are performed on same at least a portion of the plurality of feature points with same orders.

7 . The computer-implemented method of claim 1 , further comprising determining at least one feature area of the user-selected image and wherein the plurality of feature points are determined from the at least one feature area.

8 . A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
determining a plurality of feature points of a user-selected image; detecting a first plurality of interactive operations performed on at least a portion of the plurality of feature points by a user during lock screen passcode set up of a mobile computing device; storing the first plurality of interactive operations; displaying the user-selected image on a lock screen when the mobile computing device is in a locked state; detecting a second plurality of interactive operations on a touchscreen of the mobile computing device when the mobile computing device is in the locked state; and unlocking the mobile computing device if the second plurality of interactive operations match the first plurality of interactive operations.

9 . The non-transitory, computer-readable medium of claim 8 , further comprising receiving an image from a camera of the mobile computing device before determining the plurality of feature points.

10 . The non-transitory, computer-readable medium of claim 8 , wherein the plurality of feature points of the image are determined by at least one of the mobile computing device or one or more selections made by the user.

11 . The non-transitory, computer-readable medium of claim 8 , wherein the first plurality of interactive operations and the second plurality of interactive operations are at least one of a plurality of strokes that connect at least a portion of the plurality of feature points to form a pattern or a plurality of tapping operations on at least a portion of the plurality of feature points.

12 . The non-transitory, computer-readable medium of claim 8 , wherein displaying the user-selected image on the lock screen further comprises displaying the plurality of the feature points superimposed on the user-selected image.

13 . The non-transitory, computer-readable medium of claim 8 , wherein the second plurality of interactive operations match the first plurality of interactive operations when the interactive operations are performed on same at least a portion of the plurality of feature points with same orders.

14 . The non-transitory, computer-readable medium of claim 8 , further comprising determining at least one feature area of the user-selected image and wherein the plurality of feature points are determined from the at least one feature area.

15 . A computer-implemented system, comprising:
one or more computers; and one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
determining a plurality of feature points of a user-selected image;
detecting a first plurality of interactive operations performed on at least a portion of the plurality of feature points by a user during lock screen passcode set up of a mobile computing device;
storing the first plurality of interactive operations;
displaying the user-selected image on a lock screen when the mobile computing device is in a locked state;
detecting a second plurality of interactive operations on a touchscreen of the mobile computing device when the mobile computing device is in the locked state; and
unlocking the mobile computing device if the second plurality of interactive operations match the first plurality of interactive operations.

16 . The computer-implemented system of claim 15 , further comprising receiving an image from a camera of the mobile computing device before determining the plurality of feature points.

17 . The computer-implemented system of claim 15 , wherein the plurality of feature points of the image are determined by at least one of the mobile computing device or one or more selections made by the user.

18 . The computer-implemented system of claim 15 , wherein the first plurality of interactive operations and the second plurality of interactive operations are at least one of a plurality of strokes that connect at least a portion of the plurality of feature points to form a pattern or a plurality of tapping operations on at least a portion of the plurality of feature points.

19 . The computer-implemented system of claim 15 , wherein displaying the user-selected image on the lock screen further comprises displaying the plurality of the feature points superimposed on the user-selected image.

20 . The computer-implemented system of claim 15 , wherein the second plurality of interactive operations match the first plurality of interactive operations when the interactive operations are performed on same at least a portion of the plurality of feature points with same orders.
