Abstract

A method for an electronic device to restrict functionality according to working mode is provided. The method establishes a fingerprint database, wherein the fingerprint database stores at least one fingerprint of each authorized user for unlocking the electronic device, a finger type corresponding to each fingerprint stored in the fingerprint database, and a preset finger area corresponding to each finger type stored in the fingerprint database. A fingerprint of a user is obtained through a sensor. The fingerprint is matched against database for authorized status and size of fingerprint currently obtained is also analyzed and compared to a preset size of the type corresponding to the obtained fingerprint. The electronic device is unlocked for an authorized user and controlled to enter into an unrestricted working mode for an adult or into a restricted working mode for a child, according to the comparison.

Claims15

Dependent claims

An electronic device comprising:

a sensor;
a processor;
and
a storage device configured to store the fingerprint, the storage device further configured to store one or more programs which, when executed by the processor, cause the processor to:
establish a fingerprint database, wherein the fingerprint database stores at least one fingerprint of each authorized user, for unlocking the electronic device, a finger type corresponding to each fingerprint stored in the fingerprint database, and a preset finger area corresponding to each finger type stored in the fingerprint database;
obtain a fingerprint of a user through the sensor and calculate a fingerprint area of the obtained fingerprint;
search whether the obtained fingerprint is stored in the fingerprint database or not;
search for the finger type corresponding to the obtained fingerprint, and the preset fingerprint area corresponding to the finger type of the obtained fingerprint stored in the fingerprint database when the obtained fingerprint is stored in the fingerprint database;
compare the fingerprint area of the obtained fingerprint and the corresponding preset fingerprint area;
and
control the electronic device to enter into a corresponding working mode according to the comparison.
