Abstract

An unlocking method and device utilizing the same are provided. The unlocking method is disclosed, including: in response to an input pre-unlocking operation, performing a timing operation; detecting at least one input unlocking operation; determining whether a time interval from the timing operation to the input unlocking operation is equal to a predefined interval, and if the time interval from the timing operation to the input unlocking operation is equal to the predefined interval, unlocking the device, otherwise, not unlocking the device.

First claim

What is claimed is:

1 . An unlocking method for unlocking a device, comprising:
performing a timing operation in response to an input pre-unlocking operation; detecting at least one input unlocking operation; determining whether a time interval from start of the timing operation to completion of the input unlocking operation is equal to a predefined interval, and if the time interval is equal to the predefined interval, unlocking the device, otherwise, not unlocking the device.

2 . The unlocking method of claim 1 , wherein after the step of performing a timing operation in response to an input pre-unlocking operation, the unlocking method further comprises:
outputting a current-time message to indicate the time interval from the start of the timing operation to the input unlocking operation.

3 . The unlocking method of claim 2 , wherein the current-time message includes a sound, a vibration, or an image; and
the outputting step comprises: during the timing operation, outputting the current-time message based on a predetermined frequency.

4 . The unlocking method of claim 3 , wherein the step of outputting the current-time message based on a predetermined frequency further comprises: rotationally showing 10 numbers ranging from 0 to 9 in an ascending order starting from 0; and determining the current-time message according to the currently shown number and a time of rotations of the currently shown number.

5 . The unlocking method of claim 3 , wherein the step of outputting the current-time message based on a predetermined frequency further comprises: displaying symbols including at least two directional arrows when the timing operation is started, and controlling the at least two directional arrows highlighted rotating in a clockwise or anti-clockwise order based on the predetermined frequency during the timing operation; and determining the current-time message according to a currently highlighting directional arrow and a time of rotations of the currently highlighting directional arrow.

6 . The unlocking method of claim 1 , wherein before the step of detecting at least one input unlocking operation, the unlocking method further comprises:
detecting the input pre-unlocking operation for a locked device; when the input pre-unlocking operation for the locked device is detected, initiating the timing operation; determining whether the pre-unlocking operation has been lasting for a predefined period; and if the pre-unlocking operation has been lasting for the predefined period, performing another timing operation.

7 . The unlocking method of claim 1 , wherein the at least one input unlocking operation comprises an unlocking password including N numbers of sequentially configured sub-passwords, and each sub-password indicates a predefined interval;
the determining step further comprises: determining whether a time interval between a current unlocking operation and a previous unlocking operation is equal to a corresponding predefined interval which is indicated by a corresponding sub-password; if the time interval between the current unlocking operation and the previous unlocking operation is equal to the corresponding predefined interval, confirming that a sub-password has been entered; determining whether the N numbers of sub-passwords have been entered; when the N numbers of sub-passwords have been entered, unlocking the device; when the N numbers of sub-passwords have not been completely entered, performing another timing operation after one sub-password has been entered and continuing detecting the unlocking operation; and repeating the above steps until the N numbers of sub-passwords have been entered.

8 . The unlocking method of claim 1 , wherein the unlocking operation comprises at least one of a touch operation, a voice input, a keypad input and a fingerprint input, and the pre-unlocking operation comprises at least one of a touch operation, a voice input, a keypad input and a fingerprint input.

9 . The unlocking method of claim 1 , wherein the unlocking operation is different from the pre-unlocking operation.

10 . An unlocking method for unlocking a device, comprising:
entering an unlocking mode in response to an input pre-unlocking operation; detecting at least one input unlocking operation; determining whether an lasting time of the at least one input unlocking operation is equal to a predefined interval, and if the lasting time is equal to the predefined interval, unlocking the device, otherwise, not unlocking the device.

11 . The unlocking method of claim 10 , wherein after the step of detecting at least one input unlocking operation, the unlocking method further comprises:
initiating the timing operation when detect the at least one input unlocking operation, and outputting a timing message generated in the timing operation to indicate the lasting time of the unlocking operation.

12 . The unlocking method of claim 10 , wherein the at least one input unlocking operation comprises an unlocking password including N numbers of sequentially configured sub-passwords, and each sub-password corresponds to a predefined interval;
the determining step comprises: determining whether each of the lasting time of the at least one input unlocking operation is equal to each of predefined intervals which is indicated by a corresponding sub-password; if each of the lasting time of the at least one input unlocking operation is equal to each of predefined intervals; confirming that a corresponding sub-password has been entered; determining whether the N numbers of sub-passwords have been entered; when the N numbers of sub-passwords have been entered, unlocking the device; when the N numbers of sub-passwords have not been completely entered, performing another timing operation after one sub-password has been entered and continuing detecting the unlocking operation; and repeating the above steps until the N numbers of sub-passwords have been entered.

13 . A device, comprising:
a timing unit, in response to an input pre-unlocking operation, configured to perform a timing operation; a detection unit, configured to detect at least one input unlocking operation; an unlocking unit, configured to determine whether a time interval start of from the timing operation to completion of the input unlocking operation is equal to a predefined interval, and if the time interval is equal to the predefined interval, unlock the device.

14 . The device of claim 13 , further comprises:
a timing message output unit, configured to output a current-time message; a speaker, controlled by the timing message output unit, output a sound according to the predefined frequency to determine the current-time message is performing the timing operation.

15 . A device, comprising:
a detection unit, configured to enter an unlocking mode in response to an input pre-unlocking operation, and detect an input unlocking operation; a timing unit, configured to perform a timing operation to an lasting time of the input unlocking operation detected by the detection unit; and an unlocking unit, configured to determine whether the lasting time of the input unlocking operation is equal to a predefined interval, and if the lasting time of the input unlocking operation is equal to the predefined interval, unlocking the device.

16 . The device of claim 15 , further comprises:
a timing message output unit, configured to output a current-time message; a speaker, controlled by the timing message output unit, output a sound according to the predefined frequency to determine the
