Abstract

An unlocking method for a handheld electrical device with a normal mode and a limited mode is disclosed. The handheld electrical device in the normal mode is able to display all contents of an application installed on the handheld electrical device. The handheld electrical device in the limited mode is able to display only part of the contents of the application. The unlocking method includes the following steps: at least one unlocking input without a user account is obtained from an input unit of the handheld electrical device when the handheld electrical device is under a locked status. The unlocking input is compared with first preset data and second preset data to generate a comparison result. The locked status of the handheld electrical device is released according to the comparison result.

Claims

1. An unlocking method for a handheld electrical device that includes a normal mode in which the handheld electrical device is allowed to display contents of an application, and a limited mode in which the handheld electrical device is limited to display only part of the contents of the application displayed in the normal mode, wherein the unlocking method comprises:

displaying a notice that corresponds to unlocking with a second unlocking fingerprint corresponding to the limited mode on a display unit of the handheld electrical device under a locked status;

obtaining an input fingerprint acquired from a fingerprint scanner of the handheld electrical device under the locked status while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device;

releasing the locked status of the handheld electrical device and making the handheld electrical device enter the normal mode based on a determination that the input fingerprint, which is obtained while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device, matches a first unlocking fingerprint corresponding to the normal mode; and

releasing the locked status of the handheld electrical device and making the handheld electrical device enter the limited mode based on a determination that the input fingerprint, which is obtained while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device, matches the second unlocking fingerprint corresponding to the limited mode.

2. The unlocking method of claim 1, wherein the handheld electrical device is not limited to display only part of the contents of the application in the normal mode after making the handheld electrical device enter the limited mode.

3. A non-transitory computer readable storage medium for storing a program, wherein a handheld electrical device includes a normal mode in which the handheld electrical device is allowed to display contents of an application, and a limited mode in which the handheld electrical device is limited to display only part of the contents of the application displayed in the normal mode, and the handheld electrical device performs an unlocking method when the handheld electrical device reads the computer-readable storage medium and executes the program, the unlocking method comprises:

displaying a notice that corresponds to unlocking with a second unlocking fingerprint corresponding to the limited mode on a display unit of the handheld electrical device under a locked status;

obtaining an input fingerprint acquired from a fingerprint scanner of the handheld electrical device under the locked status while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device;

releasing the locked status of the handheld electrical device and making the handheld electrical device enter the normal mode based on a determination that the input fingerprint, which is obtained while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device, matches a first unlocking fingerprint corresponding to the normal mode; and

releasing the locked status of the handheld electrical device and making the handheld electrical device enter the limited mode based on a determination that the input fingerprint, which is obtained while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device, matches the second unlocking fingerprint corresponding to the limited mode.

4. The non-transitory computer readable storage medium of claim 3, wherein the handheld electrical device is not limited to display only part of the contents of the application in the normal mode after making the handheld electrical device enter the limited mode.

5. A handheld electrical device that includes a normal mode in which the handheld electrical device is allowed to display contents of an application, and a limited mode in which the handheld electrical device is limited to display only part of the contents of the application displayed in the normal mode, wherein the handheld electrical device comprises:

a display unit for displaying a notice that corresponds to unlocking with a second unlocking fingerprint corresponding to the limited mode thereon under a locked status;

a fingerprint scanner for generating an input fingerprint under the locked status while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device;

a comparing module comprising a sub-module for comparing the input fingerprint with a first unlocking fingerprint and the second unlocking fingerprint to determine whether the input fingerprint matches the first unlocking fingerprint corresponding to the normal mode, or the second unlocking fingerprint corresponding to the limited mode; and

a control module for releasing the locked status of the handheld electrical device and making the handheld electrical device enter the normal mode based on a determination that the input fingerprint, which is obtained while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device, matches the first unlocking fingerprint made by the comparing module, and

releasing the locked status of the handheld electrical device and making the handheld electrical device enter the limited mode based on a determination that the input fingerprint, which is obtained while the notice that corresponds to unlocking with the second unlocking fingerprint corresponding to the limited mode is displayed on the display unit of the handheld electrical device, matches the second unlocking fingerprint made by the comparing module.

6. The handheld electrical device of claim 5, wherein the handheld electrical device is not limited to display only part of the contents of the application in the normal mode after making the handheld electrical device enter the limited mode.
