Voice unlocking method

Abstract

The invention discloses a voice unlocking method, which is characterized by comprising the following steps: a user configures at least three different unlocking problems and an unlocking answer corresponding to each unlocking problem in an intelligent terminal; when a user carries out unlocking for the first time, randomly playing any one unlocking problem, and when the user does not carry out the unlocking for the first time, playing any one unlocking problem which is different from the previous locking if unlocking succeeds in the previous time; and if unlocking fails in the previous time, displaying an unlocking problem which is the same with the previous unlocking. The voice unlocking method does not need to calculate and compare the ripple characteristics of sound, so that the voice unlocking method is small in calculated amount, can be suitable for any intelligent terminal and is high in noise fault tolerance. Meanwhile, since the voice unlocking method has a plurality of unlocking problems, after unlocking succeeds, the new unlocking problem is answered, and if the unlocking fails, the original unlocking problem still needs to be answered again, so that other people can not easily unlock the intelligent terminal even if obtaining the unlocking answer of one unlocking problem.

Description

technical field [0001] The invention relates to an interpretation method that can be used in an intelligent terminal. Background technique [0002] There are various unlocking methods for existing smart terminals, such as password unlocking, pattern unlocking, fingerprint unlocking, voice unlocking, and eye mask unlocking. [0003] For voice unlocking, most of the existing unlocking methods are to compare the waveform characteristics of the unlocking command acquired in real time with the preset waveform characteristics, and if they match, unlocking is realized. For example, the publication number is CN103531200, and the invention patent named voice unlocking method and terminal discloses a voice unlocking method, including a terminal, wherein the voice unlocking method includes: step 102, when the terminal senses the unlocking operation, start A dedicated processor for processing voice unlocking services related to the terminal; step 104, when the terminal receives the unl...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: 1. The amount of calculation is large, and the hardware requirements for smart terminals are relatively high, so it is not suitable for promotion on smart terminals such as low-end smart phones; 2. When obtaining unlock commands in real time, the surrounding environment requirements Higher, once the surrounding sound is noisy, noise will be introduced, resulting in recognition failure

Although this method has a small amount of calculation and high tolerance to noise, it is extremely low in security, because the unlocking answer is very easy to be obtained by others.
