Method and device for achieving child safety lock by means of fingerprint identification

Abstract

The invention discloses a method and device for achieving a child safety lock by means of fingerprint identification. The method and device are used for an electronic device with a touch screen, and the touch screen has the fingerprint identification and touch identification functions. The method comprises the steps of logging into fingerprints of a limited user; judging whether the fingerprints for operating the fingerprint identification touch screen are matched with the fingerprints of the limited user, and if the fingerprints are matched with the fingerprints of the limited user, recording the time point of the operation; conducting statistic on the use time of the limited user; if the use time exceeds the preset use time threshold value, performing child safety lock operation. The device comprises the fingerprint identification touch screen, a storage used for logging into the fingerprints of the limited user and a control chip for judging whether the fingerprints for operating the fingerprint identification touch screen are matched with the fingerprints of the limited user or not. If the fingerprints for operating the fingerprint identification touch screen are matched with the fingerprints of the limited user, the time point of the operation is recorded, statistics is performed on the use time of the limited user, and if the use time exceeds the preset use time threshold value, the child safety lock operation is performed. According to the method and device, use by the limited user can be effectively limited.

Description

technical field

[0001] The invention relates to the field of child locks on electronic equipment, in particular to a method for realizing child locks by using fingerprint identification and a device for realizing the method. Background technique

[0002] Fingerprint recognition has already been realized on portable terminals, for example, a fingerprint sensor is set on a physical button of the portable terminal, or even the circuit of the fingerprint sensor is set under the touch screen, so as to perform fingerprint recognition directly on the touch screen (that is, fingerprint recognition touch screen, concurrently With fingerprint recognition function and touch recognition function), greatly expanding the application of fingerprint recognition.

[0003] At present, teenagers are increasingly dependent on mobile phones and tablet computers. Using mobile phones or tablet computers for a long time has serious adverse effects on learning and vision. Parents can only lock elec...
