Embodiment 1

[0034] Such as figure 1 As shown, this example provides a computer voice-activated screen lock and unlock system, including:

[0035] Sound collection module 10, is used for realizing the input and collection of sound signal;

[0036] The authorization management module 11 that is used to carry out authorization setting to sound password, described authorization management module 11 is connected with sound acquisition module 10, and described authorization management module 11 comprises sound feature extraction unit and password recording unit, and described sound feature extraction unit uses For extracting the voice feature of the authorized user, the password recording unit records the voice password extracted by the voice feature extraction unit;

[0037] Processing module 12, described processing module 12 is connected with sound collection module 10 and authorization management module 11 respectively, comprises sound detection unit and sound password legitimacy checking ...

Embodiment 2

[0044] Different from Embodiment 1, the sound collection module 10 in this example includes a sound card, a sound input unit and a sound output unit.

[0045] Wherein, the sound collection module 10 includes a sound card, a sound input unit and a sound output unit, and the sound card may be a pluggable sound card on a computer motherboard, or may be a sound card integrated on a computer motherboard, or may be integrated into a handheld The sound card circuit on the device; the sound input unit can be a microphone or a microphone, etc.; the sound output unit can be an earphone, a speaker, or a sound box, etc., and the sound password input prompt or alarm can also be realized through the sound output unit; and the sound card, sound input unit and The sound output unit is an accessory that comes with the computer itself. It can realize very good voice-activated lock screen and voice-activated unlock screen without adding additional costs. It has high security and is easy to operat...

Embodiment 3

[0047] Different from embodiment 1 or embodiment 2, the sound detection unit described in this example judges whether the sound signal is an effective voice input signal by detecting the sound signal collected by the sound acquisition module 10, until it is judged to be valid, then start the sound signal. Password legitimacy checking unit.

[0048] The environment where the computer is located will inevitably have other sounds or noises except the voice input of the user. The sound detection unit in this example judges whether the sound signal is valid by detecting the sound signal collected by the sound collection module 10. Voice input signal, until it is judged to be valid, then start the sound password legitimacy checking unit, can avoid receiving not valid voice input signal or other noises and start the voice password legality checking unit, avoiding the waste of energy and redundant operation, To prevent the influence of external noise, the basis for judging whether the...
