Abstract
The utility model provides a USB (universal serial bus) flash disk with a voice encryption function. The USB flash disk comprises a pickup, a voiceprint recognition chip, a memory for storing encrypted voice data, a USB flash disk master control IC (integrated circuit) and a power management circuit; both the voiceprint recognition chip and the memory are connected with the USB flash disk master control IC, and the pickup is connected with the voiceprint recognition chip; and the power management circuit is respectively connected with the pickup, the voiceprint recognition chip, the memory and the USB flash disk master control IC. The USB flash disk has the advantages that the USB flash disk can be encrypted via voice, other people cannot optionally copy contents in the USB flash disk when the USB flash disk is lost or stolen, the contents in the USB flash disk only can be copied after the USB flash disk is decrypted via the voice of an owner of the USB flash disk, and accordingly the safety and the practicality of the USB flash disk are improved.
Description
[technical field]
The utility model relates to USB flash disk, particularly a kind of USB flash disk with the voice encryption function.
[background technology]
As everyone knows, but the plug and play of movable storage device USB flash disk has realized the mobile storage performance that it is the most essential.Along with the consumer improves the cognition degree of USB flash disk, the consumer is also increasing to the demand of USB flash disk function.But also not with the USB flash disk of voice encryption function, just with the USB flash disk of encryption function, the USB flash disk of encrypting like this is easy to be deciphered by the people present USB flash disk, and after USB flash disk was lost or is stolen, other people were by deciphering the content that just can arbitrarily copy in the USB flash disk.
A kind of " USB flash disk with call function " disclosed in the prior art, see that publication number is: CN201281957, open day be: the Chinese patent of 2009.07.29, this has the USB flash disk of call function, flash chip harmony the core of the card sheet is set in the USB flash disk body, and in the storage area of described flash chip, is provided with in addition one for the program storage area of depositing the communication customer end program.The communication customer end program is used for the checking of ID identity legitimacy and makes a call.This utility model realizes integrated easily real-time phonetic communication function (call function) by the memory function in common U disk, cooperates the powerful soft-switch platform in backstage, forms the USB flash disk with call function of high performance-price ratio, high technology content.But this utility model also exists unsafe situation simultaneously, and after USB flash disk was lost or is stolen, other people just can arbitrarily copy the content in the USB flash disk.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of USB flash disk with the voice encryption function, and it has improved the security of USB flash disk.
The utility model is achieved in that a kind of USB flash disk with the voice encryption function, comprising: acoustic pickup, Application on Voiceprint Recognition chip, be used for storer, the USB flash disk master control IC of storaged voice enciphered data; Described Application on Voiceprint Recognition chip, storer all are connected with described USB flash disk master control IC, and described acoustic pickup is connected with described Application on Voiceprint Recognition chip.
Further, described USB flash disk also comprises an electric power management circuit, and this electric power management circuit is connected with described acoustic pickup, Application on Voiceprint Recognition chip, storer, USB flash disk master control IC respectively.
The utility model has the advantage of: the utility model obtains user's sound by acoustic pickup, voice signal is converted to electric signal, the Application on Voiceprint Recognition chip is identified the electric signal of conversion, USB flash disk master control IC obtains the voice encryption data in the storer, the Application on Voiceprint Recognition chip with electric signal and the voice encryption data of conversion compare judge whether identical, identical, then USB flash disk master control IC passes through the content in the USB flash disk in the present PC of USB flash disk interface body; Not identical, then can not show the content in the USB flash disk in the PC.The utility model can carry out by voice the encryption of USB flash disk, and after USB flash disk was lost or is stolen, other people just can not arbitrarily copy the content in the USB flash disk, crack by my voice, could copy the content in the USB flash disk; It has improved security and the practicality of USB flash disk.
[description of drawings]
Fig. 1 is the structural representation of the utility model the first embodiment.
Fig. 2 is the structural representation of the utility model the second embodiment.
Fig. 3 is the structural representation under the utility model use state.
[embodiment]
See also shown in Figure 1ly, a kind of USB flash disk with the voice encryption function comprises: acoustic pickup 1, Application on Voiceprint Recognition chip 2, be used for storer 3, the USB flash disk master control IC of storaged voice enciphered data; Described Application on Voiceprint Recognition chip 2, storer 3 all are connected with described USB flash disk master control IC, and described acoustic pickup 1 is connected with described Application on Voiceprint Recognition chip 2.
See also shown in Figure 2ly, be the structural representation of the utility model the second example.The difference of itself and the first embodiment is: the USB flash disk with the voice encryption function also comprises an electric power management circuit 4, and this electric power management circuit 4 is connected with described acoustic pickup 1, Application on Voiceprint Recognition chip 2, storer 3, USB flash disk master control IC respectively.Electric power management circuit 4 provides power supply for other devices of USB flash disk.This USB flash disk also can be with audio frequency IO interface (not shown), and the user can insert this interface by headset, carries out voice encryption.
Principle of work of the present utility model is as follows:
As shown in Figure 3, USB flash disk is inserted in the PC, advanced lang sound is encrypted in advance: user's rear USB flash disk of sounding obtains user's sound by acoustic pickup 1, convert voice signal to electric signal, Application on Voiceprint Recognition chip 2 is identified the rear voice encryption data being kept at by USB flash disk master control IC with electric signal and is finished pre-ciphering process in the storer 3.The user is when using USB flash disk, acoustic pickup 1 obtains user's sound, voice signal is converted to electric signal, the electric signal of 2 pairs of conversions of Application on Voiceprint Recognition chip is identified, USB flash disk master control IC obtains the voice encryption data in the storer, Application on Voiceprint Recognition chip 2 is compared electric signal and the voice encryption data of conversion and is judged whether identically, identical, and then USB flash disk master control IC passes through the content in the USB flash disk in the present PC of USB flash disk interface body; Not identical, then can not show the content in the USB flash disk in the PC.
In a word, the utility model can carry out by voice the encryption of USB flash disk, and after USB flash disk was lost or is stolen, other people just can not arbitrarily copy the content in the USB flash disk, crack by my voice, could copy the content in the USB flash disk; It has improved security and the practicality of USB flash disk.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
