Composite identity authentication-based network trading system

Abstract

The invention provides a composite identity authentication-based network trading system. The system comprises a verification device and multiple terminals. The system further comprises a privacy database used for recording privacy information of a user, a first private network which records multiple pieces of authentication encryption information, a second private network which records a mapping relationship linked with the privacy database, and a public network; the terminals are linked with the first private network, the second private network and the public network, and corresponding network nodes are formed; the terminals accessing the private network become nodes in the private network, and the application of the multiple nodes further ensures the security of data storage in the private network; and by applying settings of the first private network and the second private network, the universality and security of an information obtaining mode are taken into account while the terminal authentication requirements of different security level settings are met.

Description

technical field [0001] The invention relates to the technical field of network transactions, in particular to a complex identity authentication network transaction system. Background technique [0002] In the prior art, there are various authentication methods, such as passwords (withdrawal passwords, account login passwords, etc.), biological information (fingerprints, iris, sound waves, vein information, etc.), physical information (keys, smart cards, NFC, etc.) Verification application; however, password verification is easy to be obtained by others through recording, monitoring, etc., and the security is low; biometric verification may be cracked by simulation and copying, and biometric information is mainly stored by a single department or terminal and applied to different The terminal needs to be repeatedly entered, and the application is inconvenient; the verification of physical information is easy to be copied or stolen, or the application is invalid due to the loss...

AI Technical Summary

Problems solved by technology

When the user is shopping on the network platform, the user needs to enter his own relevant information to clarify the user's identity, and then further confirm the order information and submit it. The electronic transaction system receives the order information submitted by the user, and then deducts the user's account with the help of the payment system. cash, thus completing a transaction process, which is lengthy and unable to adapt to the growing network transaction environment
