METHOD AND APPARATUS FOR UNLOCKING A SCREEN AND MOBILE ELECTRONIC DEVICE
A method and apparatus for unlocking a screen and a mobile electronic device. The method includes: triggering an unlocking program based on biometric feature identification in the mobile electronic device by approaching or contacting a near field communication tag by the mobile electronic device; and unlocking a screen of the mobile electronic device by using a biometric feature of a user. Hence, not only can security be ensured by the NFC tag, but also the screen can be unlocked via the biometric feature, which may improve convenience by not requiring a user to memorize a password (improving user experience).
1 . A method performed by a mobile electronic device for unlocking a screen of the mobile electronic device, the method comprising:
sensing with the mobile electronic device and a near field communication tag;
determining with the mobile electronic device whether the near field communication tag is an approved near field communication tag;
when the sensed near field communication tag is the approved near field communication tag:
receiving a biometric feature of a user; and
determining whether the received biometric feature matches an authorized biometric feature;
when the received biometric feature matches the authorized biometric feature, unlocking a screen of the mobile electronic device.
2 . The method according to claim 1 , wherein:
when the mobile electronic device is rooted or switched on and the approved near field communication tag is not sensed by the mobile device, requiring a passcode to unlock the screen of the mobile electronic device.
3 . The method according to claim 1 , wherein the biometric feature of the user comprises at least one of the following of the user: a fingerprint, a face, an iris, a palm print, or a voice.
4 . The method according to claim 1 , wherein the method further comprises:
when the authorized near field communication tag 1 s sensed, an unlocking program is executed and the unlocked program receives the biometric feature from the user.
5 . The method according to claim 1 , wherein the near field communication tag comprises a universal tag, and a configuration program is used in the mobile electronic device to identify the near field communication tag as the authorized near field communication tag.
6 . The method according to claim 5 , wherein the configuration program is a universal third-party program.
7 . The method according to claim 1 , wherein the near field communication tag comprises a specific tag of the mobile electronic device, and the near field communication tag and the mobile electronic device are bound in advance.
8 . The method according to claim 7 , wherein the near field communication tag contains identification information of the mobile electronic device.
9 . A mobile electronic device comprising:
a screen;
a near field communication sensor configured to sense a near field communication tag;
a biometric sensor configured to generate biometric feature data from a biometric feature of a user of the mobile electronic device;
a processor configured to:
lock the screen to prevent operation of the mobile electronic device by an unauthorized user;
receive data from the sensor regarding the near field communication tag;
determining whether the near field communication tag is an approved near field communication tag;
when the sensed near field communication tag is the approved near field communication tag:
receiving the biometric feature data from the biometric sensor;
determining whether the received biometric feature matches an authorized biometric feature;
when the received biometric feature matches the authorized biometric feature, unlocking a screen of the mobile electronic device.
10 . The mobile electronic device according to claim 9 , wherein when the mobile electronic device is rooted or switched on and the approved near field communication tag is not sensed by the mobile device, requiring a passcode to unlock the screen of the mobile electronic device.
11 . The mobile electronic device according to claim 9 , wherein the biometric feature of the user comprises at least one of the following of the user: a fingerprint, a face, an iris, a palm print, or a voice identification.
12 . The mobile electronic device according to claim 9 , wherein the processor is further configured to:
when the authorized near field communication tag 1 s sensed, execute an unlocking program, such that the unlocked program receives the biometric feature data.
13 . The mobile electronic device according to claim 9 , wherein the near field communication tag comprises a universal tag, and the processor executes a configuration program to identify the near field communication tag as the authorized near field communication tag.
14 . The mobile electronic device according to claim 9 , wherein the near field communication tag comprises a specific tag of the mobile electronic device, and the near field communication tag and the mobile electronic device are bound in advance.
15 . The mobile electronic device according to claim 14 , wherein the near field communication tag contains identification information of the mobile electronic device.
