Problems solved by technology

[0004] (1) Because there is only one encryption and decryption method, it is easy to be decrypted
[0005] (2) Compatibility issues, if the calling end and the receiving end use different brands of mobile phones, encrypted communication cannot be implemented
Because the technology is implemented in the hardware circuit of the mobile phone, the technology cannot be upgraded (Upgrade)
[0007] (4) The previous case does not have the effect of anti-eavesdropping

Embodiment Construction

[0027] figure 1 It is a structural diagram of the communication system of the present invention. The communication parties use the Bluetooth headset devices 11 and 21 of the present invention to perform encryption, decryption and data transmission, and use smart phones with built-in Bluetooth headset modules 102 and 202 to perform voice encryption data In the communication, if any party does not use the Bluetooth headset device, only general communication can be carried out, and there is no encryption effect. Such a system structure is one of the characteristics of the present invention. Compared with the structure of the previous case, this case has 100% compatibility to any digital voice communication mobile phone (after the second generation mobile phone), no matter whether the two users use the same brand Whether the mobile phones use the same mobile phone chipset or the same mobile phone operating system are all compatible, compared with the prior art, the present inventi...

Abstract

The invention discloses a mobile phone communication anti-eavesdropping system that implements encryption and decryption at the Bluetooth earphone end. Both communication parties use a Bluetooth earphone device and a smart phone device, wherein the Bluetooth earphone device has an encryption and decryption unit for encryption and decryption. The encryption and decryption unit transmits the encrypted voice data to the smart phone device; and decrypts the encrypted voice data from the smart phone device, and the decrypted voice data is output through the loudspeaker.

Description

technical field [0001] The invention relates to a mobile phone communication anti-eavesdropping system that implements a digital voice encryption method in a bluetooth earphone device. The encryption method is used to realize the anti-eavesdropping effect during mobile phone communication, and belongs to the technical field of bluetooth communication and mobile phone communication. Background technique [0002] There are two general mobile phone monitoring (eavesdropping) methods, one is for government inspection units, foreign intelligence units or commercial spies to monitor the target object in the exchange center computer room or by setting up a communication monitoring system for their special purposes. The mobile phone number (door number) is used for call monitoring, and the mobile phone user cannot detect this type of monitoring; the other is private monitoring, usually when the mobile phone is installed (intruded) with monitoring software, and the common method is wh...
