Abstract
The disclosure discloses a method and device for unlocking a mobile terminal, which relate to the technical field of mobile terminals. The method includes the following steps that: when a mobile terminal is in a locking state, a time length for an object to stay close to a screen of the mobile terminal and to be maintained within a pre-determined distance range is determined; a corresponding unlocking signal is generated according to the time length; and the mobile terminal is unlocked according to the unlocking signal. According to the disclosure, the mobile terminal can be encrypted and unlocked by using a distance sensor, which brings both great practicability and high confidentiality.
Claims10
A method for unlocking a mobile terminal, comprising:
- when a mobile terminal is in a locking state, determining a time length for an object to stay close to a screen of the mobile terminal and to be maintained within a pre-determined distance range;
- generating a corresponding unlocking signal according to the time length;
- and
- unlocking the mobile terminal according to the unlocking signal;
- wherein generating the corresponding unlocking signal according to the time length comprises:
- comparing the time length with a pre-set time length;
- and
- when the time length is greater than the pre-set time length, generating an unlocking signal, which is used for indicating that the time length is greater than the pre-set time length, and when the time length is smaller than or equal to the pre-set time length, generating an unlocking signal, which is used for indicating that the time length is smaller than or equal to the pre-set time length;
- wherein unlocking the mobile terminal according to the unlocking signal comprises:
- combining the unlocking signal with one or more previously-generated unlocking signals to form an unlocking signal sequence;
- comparing the unlocking signal sequence with a pre-set signal sequence;
- and
- when the unlocking signal sequence is matched with the pre-set signal sequence, unlocking the mobile terminal, and when the unlocking signal sequence is not matched with the pre-set signal sequence, maintaining in the locking state.
A mobile terminal unlocking device, comprising:
- a time determination element, configured to determine, when a mobile terminal is in a locking state, a time length for an object to stay close to a screen of the mobile terminal and to be maintained within a pre-determined distance range;
- a signal generation element, configured to generate a corresponding unlocking signal according to the time length;
- and
- an unlocking element, configured to unlock the mobile terminal according to the unlocking signal;
- wherein the signal generation element comprises:
- a signal comparison sub-element, configured to compare the time length with a pre-set time length;
- and
- a signal generation sub-element, configured to generate, when the time length is greater than the pre-set time length, an unlocking signal, which is used for indicating that the time length is greater than the pre-set time length, and generate, when the time length is smaller than or equal to the pre-set time length, an unlocking signal, which is used for indicating that the time length is smaller than or equal to the pre-set time length;
- wherein the unlocking element comprises:
- a signal combination sub-element, configured to combine the unlocking signal with one or more previously-generated unlocking signals to form an unlocking signal sequence;
- a sequence comparison sub-element, configured to compare the unlocking signal sequence with a pre-set signal sequence;
- and
- an unlocking sub-element, configured to unlock, when the unlocking signal sequence is matched with the pre-set signal sequence, the mobile terminal, and maintain, when the unlocking signal sequence is not matched with the pre-set signal sequence, in the locking state.
