Abstract

The invention discloses a Bluetooth headset shield and a digital signature method of the Bluetooth headset shield. Information of a digital signature to be signed by a user is played through a headset of the Bluetooth headset through the first-generation Bluetooth headset shield; compared with a method for installing a display screen on the Bluetooth headset shield and displaying digital signature information through the display screen in the prior art, the Bluetooth headset shield and the digital signature method have the advantage that security of the digital signature information is improved on the basis of not increasing the hardware cost of the Bluetooth headset shield; by means of the method for displaying the digital signature information through the headset, people except the user are prevented from hearing or seeing the digital signal information, and security of the digital signature information is further improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a bluetooth earphone shield and a digital signature method thereof. Background technique [0002] Since the first-generation Bluetooth headset shield does not have a display screen and cannot display transaction information on the Bluetooth headset shield, there may be pending transactions when the terminal communicating with the first-generation Bluetooth headset shield sends the corresponding digital signature information to the Bluetooth headset shield. The risk that the digital signature information signed by the user will be illegally tampered with. The second-generation Bluetooth headset shield is equipped with a display screen, so the second-generation Bluetooth headset shield can display the digital signature information to be signed by the user through the display screen, for the user to confirm based on the displayed digital signature information and trigger the seco...
