Abstract

The invention provides a data transmission method and system. The data transmission method comprises steps that an external member device receives trade information sent by a terminal and transmits the trade information to a smart password device; the smart password device extracts key information of the trade information and displays key information to be verified by users; the smart password device receives a verification instruction and transmits signing information to the external member device; the external member device transmits the signing information to the terminal; wherein before the smart password device receives the verification instruction, the smart password device enters a password input mode preset on the external member device, receives passwords input by the external member device, and verifies correctness of the passwords. Therefore, the passwords can be input by means of the password input mode preset on the external member device, different external member devices can be used according to different security levels of password input modes preset on the external member devices, and security of password input is improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a data transmission method and system. Background technique [0002] With the great convenience brought to people by the rapid development of the network, people rely more and more on the network for various activities, such as the transmission of network files and online banking transactions, which have gradually become an indispensable part of people's life and work. Since the network is a virtual environment after all, there are too many insecure factors, and in the network environment, data interaction network activities are bound to be carried out, especially network activities such as online banking and confidential file transmission, which have a great impact on the network. Therefore, people began to vigorously develop network information security technology. [0003] In order to improve the security of network information transmission, people have developed ...
