Problems solved by technology

[0002] As a kind of Bluetooth communication technology, Bluetooth headset adopts wireless communication transmission mode, which may cause user data to be intercepted by others during transmission.
At present, the security measures provided by the frequency hopping mechanism of the Bluetooth system focus on solving the transmission interference caused by other Bluetooth devices in the system, but when transmitting data wirelessly, data stealers can easily shield themselves from users' discovery, so It is far from enough to rely solely on the protection mechanism of frequency hopping technology, and further technical measures are needed to ensure the confidentiality of user data
[0003] In addition, the currently used Bluetooth communication encryption protection technology also uses digital certificates to generate session keys to encrypt and protect voice signals. The generated key is not easy to remember, and the key may be stolen, which causes inconvenience to users of encrypted communication
[0004] In addition, the session key is often used in the process of network communication to encrypt the client's call information. Currently, it is mostly "one-time pad", that is, the general session key is temporarily generated during each session and is "destroyed" after a session ends. ", once the session key is intercepted during a session, the user's subsequent communication security cannot be guaranteed
[0005] Existing bluetooth earphones with encryption function, such as "a voice encryption bluetooth earphone with fingerprint recognition" disclosed in Chinese patent CN203279187U, are responsible for user identity authentication and start encryption chip through fingerprint sensor and fingerprint recognition management chip, which can solve the problem of bluetooth For the security issue of the earphone itself, the encryption chip is responsible for encrypting / decrypting the voice chip, which can solve the security problem of voice transmission, but the Bluetooth earphone still has disadvantages such as high cost, and also cannot guarantee the user’s subsequent communication security

Embodiment 1

[0040] Such as figure 1 As shown, a bluetooth earphone includes an earphone shell and a circuit board 1 disposed in the earphone shell, and the circuit board 1 is provided with a central processing unit 10 and a voiceprint recognition device 11 connected thereto.

[0041] The central processing unit 10 is configured to detect whether a verification and recognition instruction is received and judge whether to encrypt the voice according to the voiceprint recognition result. When the command is recognized, it is determined not to perform voice encryption processing. The central processing unit 10 includes a bluetooth chip that can be connected with a communication terminal.

[0042]The voiceprint recognition device 11, when the central processing unit 10 judges to perform voice verification and recognition processing, performs voiceprint verification and recognition on the collected voice signal, and feeds back the voiceprint recognition result to the central processing unit. I...

Embodiment 2

[0051] Such as Figure 1-Figure 2 As shown, a bluetooth earphone, the structure of the bluetooth earphone of this embodiment is the same as that of embodiment 1, and only the specific structure of the reference voiceprint retrieval module 112 is different, specifically:

[0052] Such as Figure 4 As shown, the reference voiceprint retrieval module 112 includes a wireless communicator 1123, the wireless communicator 1123 is connected to the cloud server 1124 through a wireless signal, and the cloud server 1124 includes a voiceprint database, which stores pre-collected reference voiceprints The characteristic signal is used for real-time retrieval through wireless signals during voiceprint verification.

[0053] The voiceprint database of the cloud server 1124 can pre-store the reference voiceprint feature signal information of all trusted users. The trusted users can be set to one or more according to actual needs. During verification, the wireless communicator 1123 Connect w...

Embodiment 3

[0055] Such as Figure 5 As shown, a bluetooth earphone comprises an earphone shell and a circuit board 1 arranged in the earphone shell, and the circuit board 1 is provided with a central processing unit 10, a voiceprint recognition device 11, a voice recognition device 12, encryption / decryption device 13 and timer 14 .

[0056] The central processing unit 10 is configured to detect whether a verification and recognition instruction is received and judge whether to encrypt the voice according to the voiceprint recognition result. When the recognition instruction is used, it is determined that the voice encryption process is not performed; the voiceprint recognition device 20 is configured to perform voiceprint verification and recognition on the collected voice signal when the central processing unit 10 determines to perform voice verification and recognition processing, and convert the voiceprint The recognition result is fed back to the central processing unit 10. If the v...

Abstract

The invention relates to a bluetooth earphone, which includes an earphone shell and a circuit board arranged in the earphone shell, and the circuit board is provided with: a central processing unit configured to detect whether a verification and identification instruction is received and according to the voiceprint identification result Judging whether to perform encryption processing on the voice, wherein, if the verification and recognition instruction is received, it is determined to perform voice verification and recognition processing, and if the verification and recognition instruction is not received, it is determined not to perform voice encryption processing; and the voiceprint recognition device, in the When the above-mentioned central processing unit decides to carry out voice verification and recognition processing, the verification and recognition of the voiceprint is performed on the collected voice signal, and the voiceprint recognition result is fed back to the central processing unit; if the voiceprint recognition is successful, the central processing unit determines to proceed Voice encryption processing, if the voiceprint recognition fails, the central processing unit determines not to perform voice encryption processing. Compared with the prior art, the present invention has the advantages of high communication security and the like.
