An NFC-based dynamic password identity authentication method and system

Abstract

The invention relates to the technical field of information security, in particular to a dynamic password identity authentication method and system and provides a dynamic password identity authentication method and system based on near field communication (NFC). The method includes that an NFC module provides a radio-frequency field; a tag with first identity information inside of a user induces the radio-frequency field, and meanwhile, the first identity information is sent to the NFC module; identity authentication modules obtain the first identity information which is received by the NFC module, and the first identity information is verified; if the verification of the first identity information succeeds, a unique identify number which is related to the first identity information is obtained and verified, and a secret key seed which is related to the identify number is obtained; a first identity authentication module is combined with the secret key seed to generate a dynamic password; the dynamic password is input to finish identity authentication. According to the dynamic password identity authentication method and system based on NFC, the identity authentication modules are independent of all application programs in devices, one dynamic token can be simultaneously used at various occasions, user operation is simplified and facilitated, and user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a dynamic password identity authentication method and system. Background technique [0002] With the development of the mobile Internet, dynamic password technology has become the mainstream of identity authentication technology. It is a safe and convenient account anti-theft technology that can effectively protect the authentication security of transactions and logins. Therefore, it is widely used in enterprises, online games, finance, etc. field. There are more and more domestic and foreign companies engaged in the research and development and production of dynamic passwords. At present, the more common dynamic tokens include hardware dynamic tokens and software dynamic tokens. [0003] A dynamic password is a dynamic password that is automatically updated every certain time according to a special algorithm. The time-based dynamic password generates a time-related...

Problems solved by technology

[0005] The above-mentioned patent discloses the commonly used dynamic password authentication system and method at present. However, when the existing dynamic password is used, the identity security authentication platform must be bound with a specific application to realize one-to-one service according to the user's needs. When the user's When the application needs to be changed, it is necessary to re-bind the identity security authentication platform with the specific application. The operation is cumbersome. It has become a requirement to improve user experience while ensuring user security.
