Smart card registration entry method based on password and biological characteristics

Abstract

The invention discloses a smart card registration entry method based on a password and biological characteristics. The method comprises a registration step and an entry step, wherein the registration step further comprises the following steps of transmitting a user identity label, the password and the biological characteristics to a registration center, carrying out the encryption through the registration center to obtain a password encrypted value and a biological characteristic encrypted value, and storing the password encrypted value, the biological characteristic encrypted value and an encryption method to a smart card; and the entry step further comprises the following steps of utilizing the smart card to encrypt the identity information and password, inputted by a user through the same method to obtain password verification information, determining that the password is correct if the password verification information is identical to the password encrypted value, reading the biological characteristics to be verified and inputted by the user through the smart card, restoring the biological characteristics in registration according to the password and biological characteristic encrypted value, verifying the matching degree, and succeeding in entry if the matching degree is greater than a set threshold value. Due to the adoption of the smart card registration entry method, different known attacks can be more effectively resisted, and only the user can enter the system.

Description

technical field [0001] The invention relates to the fields of information security and network technology, in particular to an identity authentication method based on passwords and biometric features. Background technique [0002] The rapid development of network communication technology has made more and more people accustomed to using the services provided by the network, such as e-commerce, e-government, electronic logistics and so on. Before users log in to the system to obtain services, they must first verify the legitimacy of their identity to prevent illegal login. [0003] In recent years, many authentication methods have emerged. In 2011, Cheng-Chi Lee et al. proposed a remote user authentication method. In 2012, Cheng-Chi Lee et al. proposed an improved remote user login method. In the same year, Chun-Ta Li et al. also proposed a password-based and smart card-based authentication method. User authentication mechanism. The above studies are all based on passwords...

Problems solved by technology

These studies have introduced biometrics. After registration, the biometrics will be hashed and compared with the hash value of the user’s input biometrics during verification. However, due to the randomness of biometrics collection and the characteristics of hashing, In practical applications, this kind of verification is almost impossible to achieve
