Abstract

An embodiment of the invention discloses a data communication method, a data communication system, a client and a server. The data communication method comprises the steps of transmitting a communication request by the client to the server; generating at least one bit code by the server according to a first preset role in response to the communication request, and transmitting information which carries the at least one bit code to the client by the server; generating at least one input block by the client, wherein the number of the input blocks corresponds with the at least one bit code; transmitting the data of the at least one input block to the server by the client as verification data; comparing bit data which correspond with each bit code in the at least one bit code with the verification data by the server, and when the bit data which correspond with each bit code in the at least one bit code are same with the verification data, transmitting a successful information code by the server to the client. The data communication method, the data communication system, the client and the server have advantages of improving password safety and reducing decryption risk of the password.

Description

technical field [0001] The present application relates to the field of data communication, in particular to a data communication method and system, as well as a client and a server. Background technique [0002] In real life, password authentication is required to confirm the user's identity in many occasions. Specifically, examples include: a user logs in to a website, consumes in a shopping mall, withdraws money in a bank or an ATM, and the like. Users will first register on the website, or go to a bank to open an account. When registering or opening an account, the user will set a username and password for subsequent identity verification. After completing the registration or opening an account, the user can use the user name and password to log in to the website, use online banking to shop, or use the bank card to withdraw money at the bank or ATM. [0003] Existing websites and bank systems require users to enter a complete account and password. The system will furth...
