Abstract

The utility model relates to a USB flash disk is encrypted to vocal print belongs to the computer peripheral field, including the USB flash disk body, set up a USB interface and pop out the switch on the USB flash disk body, the USB interface pops out the switch and connects the USB interface, and the USB interface pops out and sets up the electronic lock on the switch, the utility model discloses a voiceprint recognition system controls opening of on USB flash disk electronic lock, and owner that can only the USB flash disk just can open the USB interface and pop out the switch, exposes data interface, looks over the content in the USB flash disk, and the security is high, and data in the protection USB flash disk that can be fine need not worry that password or key are stolen.

Description

A kind of vocal print encrypted U disk

Technical field

The utility model relates to a kind of USB flash disk, specifically, is a kind of vocal print encrypted U disk.

Background technology

The data that present USB flash disk widespread use is much important and information are stored on USB flash disk, and the event that the data on USB flash disk are stolen happens occasionally, and are not easy to find, bring loss to people individual and country.Chinese patent CN104281819 discloses a kind of encrypted U disk, and adopt password jam plate to substitute traditional key unlocking mode, but password is once be stolen, password jam plate performs practically no function.

Vocal print is the sound wave spectrum carrying verbal information of electricity consumption acoustic instrument display.Modern scientific research shows, vocal print not only has specificity, and has the feature of relative stability.After growing up, the sound of people can keep long-term relatively stable constant.Experiment proves, no matter talker deliberately imitates other people sound and the tone, or whisper in sb.'s ear is talked softly, even if imitate remarkably true to life, its vocal print is but identical all the time.For identical twin, fingerprint is identical, but its vocal print is different, and visible vocal print has more unicity than fingerprint, and cannot be stolen.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of vocal print encrypted U disk.

For achieving the above object, the utility model provides following technical scheme:

The utility model relates to a kind of vocal print encrypted U disk, comprise USB flash disk body, USB flash disk body arranges a USB interface and ejects switch, USB interface ejects switch and connects USB interface, USB interface ejects on switch and arranges electronic lock, it is characterized in that, described electronic lock connects a drive unit, described drive unit connects central controller, described central controller connects Application on Voiceprint Recognition device, vocal print contrast device and vocal print storer is comprised in described Application on Voiceprint Recognition device, described vocal print contrast device connects vocal print collector respectively, vocal print storer, described central controller also connects siren driver, described siren driver connects GPS locator.

As further scheme of the present utility model, described central controller adopts 51 single-chip microcomputers.

Compared with prior art, good effect of the present utility model is:

1. the utility model adopts Voiceprint Recognition System to control the unlatching of electronic lock on USB flash disk, the owner of USB flash disk could can only open USB interface ejection switch, expose data-interface; check the content in USB flash disk; security is high, can be good at protecting the data in USB flash disk, do not need to worry password or key stolen.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of vocal print encrypted U disk;

Fig. 2 is the principle schematic of described electronic lock.

Mark in accompanying drawing 1 is respectively: 1.U dish body; 2. data-interface; 3.USB interface ejects switch; 4. electronic lock.

Embodiment

The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

As Fig. 1, shown in 2, a kind of vocal print encrypted U disk, comprise USB flash disk body 1, USB flash disk body 1 arranges a USB interface and ejects switch 3, USB interface ejects switch 3 and connects USB interface 2, USB interface ejects on switch 3 and arranges electronic lock 4, it is characterized in that, described electronic lock connects a drive unit, described drive unit connects central controller, described central controller connects Application on Voiceprint Recognition device, vocal print contrast device and vocal print storer is comprised in described Application on Voiceprint Recognition device, described vocal print contrast device connects vocal print collector respectively, vocal print storer, described central controller also connects siren driver, described siren driver connects GPS locator.

Wherein, described central controller adopts 51 single-chip microcomputers.

Specific implementation process of the present utility model is as follows:

Electronic lock on USB flash disk is by identifying that vocal print is opened, when the vocal print that vocal print collector collects and the vocal print in vocal print storer through vocal print contrast device contrast consistent time, central controller controls drive unit unlocking electronic lock, USB interface ejects switch open, data-interface is out exposed, can carry out data transmission; When the contrast of vocal print contrast device is inconsistent, central controller controls siren driver starts, and open GPS locator, the owner being convenient to USB flash disk finds USB flash disk simultaneously.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.

Claims

1. a vocal print encrypted U disk, comprise USB flash disk body, USB flash disk body arranges a USB interface and ejects switch, USB interface ejects switch and connects USB interface, USB interface ejects on switch and arranges electronic lock, it is characterized in that, described electronic lock connects a drive unit, described drive unit connects central controller, described central controller connects Application on Voiceprint Recognition device, vocal print contrast device and vocal print storer is comprised in described Application on Voiceprint Recognition device, described vocal print contrast device connects vocal print collector respectively, vocal print storer, described central controller also connects siren driver, described siren driver connects GPS locator.

2. a kind of vocal print encrypted U disk according to claim 1, it is characterized in that, described central controller adopts 51 single-chip microcomputers.
