Problems solved by technology

[0004] However, the voiceprint characteristics will also vary with the user's mood and state. For example, when the user is excited, the voiceprint characteristics such as volume, tone, and rhythm will be higher than normal. In similar situations, When the voiceprint features are compared, the user's voice may not be recognized, and eventually the user cannot unlock or needs to perform multiple operations to complete the unlock.
[0005] That is to say, there is a problem of low unlocking efficiency in the existing technology about using voiceprint for unlocking

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] In this embodiment, an unlocking method is provided. In the process of using voiceprint to unlock, the user's physiological state of the human body can be considered to improve the unlocking efficiency of voiceprint unlocking. The implementation of this method can rely on computer programs. The computer program can run on the computer system based on the von Neumann architecture, and the computer program can be a screen unlocking application prog...

Abstract

The embodiment provides an unlocking method and a terminal. The unlocking method comprises following steps: receiving an unlocking request inputted by a user, triggering a sound collection device to collect video data inputted by the user according to the unlocking request and extracting video-print feature value of sound data; obtaining human physiology indicator data collected by a sensor and determining video-print feature reference value and a feature matching mode corresponding to human physiology indicator data based on human physiology indicator data; determining whether video-print feature value is matched with video-print feature reference value or not according to the feature matching mode; and performing unlocking operation when video-print feature value is matched with video-print feature reference value. The unlocking method and the terminal are adopted in order to increase unlocking efficiency of a video-print unlocking scheme.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an unlocking method and device. Background technique [0002] The so-called voiceprint (Voiceprint) is the sound wave spectrum that carries speech information displayed by electroacoustic instruments. Modern scientific research shows that voiceprint is not only specific, but also relatively stable. After adulthood, the human voice can remain relatively stable for a long time. Experiments have proved that no matter whether the speaker deliberately imitates the voice and tone of others, or whispers softly, even if the imitation is vivid, the voiceprint is always different. [0003] Voiceprint unlocking is one of the commonly used screen unlocking methods for mobile phones. In actual use, users can usually set voice unlock commands. While recognizing semantics, the mobile phone also needs to compare the corresponding voiceprint features. It will be unlocked when all t...
