Method for carrying out identity recertification on particular operation of information system by using Usb key technology

Abstract

The invention relates to a practical application of a method for carrying out identity recertification on particular operation (such as cost-free operation of a charge system, an information deleting operation of an illegal system) in a software system in a public security traffic industry. The method comprises the following steps: binding one Usb Key with a user which has particular operation authority; then binding the unique serial number of the Usb Key with user information; when the user carries out the particular operation, firstly checking whether the Usb Key is inserted or not, if not, exiting a system; if so, verifying whether the unique serial number of the Usb Key is accurate or not; and carrying out the operation only if the unique serial number of the Usb Key is accurate, thereby avoiding extensive damage caused by the malevolence operation performed by others due to code leakage.

Description

technical field [0001] The present invention relates to the practical application of the identity re-authentication method in the public security traffic management industry during special operations in the software system (such as free operation of the toll system and deletion of information in the illegal system). Bind the unique serial number of the Usb Key with the user information. When the user performs a special operation, first check whether the Usb Key is inserted. If not, the system exits; It can be operated to avoid malicious operations by others due to password leakage, resulting in huge losses. Background technique [0002] In the information system, the means of user identity authentication can be roughly divided into these three types. Proving a person’s identity only by meeting one condition is called single-factor authentication. Since only one condition is used to judge the user’s identity, it is easy to be identified. Counterfeiting, which can prove a per...

Problems solved by technology

[0013] Biometric authentication is based on biometric identification technology, affected by the maturity of the current biometric identification technology, the use of biometric authentication still has great limitations

First of all, the accuracy and stability of biometric identification needs to be improved, especially if the user's body is affected by injuries or stains, it often leads to the failure of normal identification, resulting in the situation that legitimate users cannot log in

Secondly, due to the large investment in research and development and the small output, the cost of the biometric authentication system is very high. At present, it is only suitable for some occasions with very high security requirements, such as banks and troops, and it cannot be widely promoted.
