Example Embodiment

[0044] Example 1

[0045] This embodiment provides a data transmission system, figure 1 It is a schematic diagram of the structure of the data transmission system provided in this embodiment. Such as figure 1 As shown, the data transmission system includes a terminal 10 and an electronic signature device 20. The data transmission between the terminal 10 and the electronic signature device 20 includes sending its own Bluetooth address to each other, the terminal 10 sending the first information to the electronic signature device 20, and the electronic signature device 20 sending the processed second information to the terminal 10. Wait. The specific data transmission system includes:

[0046] The terminal 10 establishes an NFC connection with the electronic signature device 20; the electronic signature device 20 sends the Bluetooth address of the electronic signature device 20 to the terminal 10 through the NFC connection; the terminal 10 sends the Bluetooth address and the first ...

Abstract

The invention provides a data transmission method. The data transmission method includes that the terminal is in NFC connection with an electronic signature device; the electronic signature device sends a Bluetooth address of the electronic signature device to the terminal through NFC connection; the terminal sends the Bluetooth address of the terminal and a first message to the electronic signature device through NFC connection; the electronic signature device processes the first message and obtains a second message and broadcasts the Bluetooth address of the electronic signature device; the terminal performs Bluetooth address scanning and acquires the Bluetooth address obtained through the NFC connection; the terminal establishes Bluetooth connection with the electronic signature device corresponding to the acquired Bluetooth address; the electronic signature device sends the second message to the terminal through Bluetooth connection. According to the invention, by the wireless connection means based on the combination of NFC technology and Bluetooth technology, abrasion of a wired interface is avoided, so that complicated matching processes of Bluetooth connection are avoided and data theft and interception are prevented. Therefore, data security is ensured, data transmission rate is improved and user experience is improved.

Description

technical field [0001] The present invention relates to the field of electronic signatures, in particular to a data transmission method, terminal, electronic signature device and system based on Near Field Communication (NFC) technology and Bluetooth technology. Background technique [0002] At present, in the field of electronic signatures, the electronic signature devices suitable for online banking (such as ICBC’s U-Shield, Agricultural Bank’s K-Bao, etc.) are connected to terminals (such as PCs, mobile phones, etc.) by wired connections, such as USB ports, audio interface etc. Due to repeated plugging and unplugging operations, the interface is easy to wear and tear, resulting in poor contact between the electronic signature device and the terminal, thus affecting the data transmission between the two. [0003] In addition, if Bluetooth is used for data transmission between the terminal and the electronic signature device, because the pre-connection and pairing process ...
