The Automatic Security Login Technology Research And The Realization

Web application software system used in Zhongyuan oil field uses the method of "user name + password" to carries on the user the status authentication and the access control, but this authentication method has the very big security hidden danger, needs one kind to be safer, the more convenient user status authentication plan safeguards the information system to automatic security login. In order to solve this problem, this paper has conducted the research and the application to the digital certificate and the fingerprint recognition technology.This paper has carried on the introduction to the CA authentication technology, introduced the Construction of Zhongyuan oil field certificate authentication (CA), the application process of CA certificate , described how the digital certificate used on Zhongyuan oil field security Web application.This paper also introduces the biological identification technology, and conducts the research to the present field popular six biology identification technology, compares technical characteristic with each other; finally chooses fingerprint identification technology to do pivot research and application exploitation, and introduces its technical characteristic and the installation and use ways of corresponding equipment in detail.Based on the intensive comprehension to the technology, we take the Zhongyuan oil field science and technology information management system as the example, the paper designs and constitutes the database of biology identify characteristic of the system users; realizes the users'fingerprint login function based on the mode of web pages through ASP program; lists detailed realization codes; based on the former system interface and through the rebuilding of former system login interface, finally realizes to offer two kinds of login interfaces (traditional login mode and fingerprint identification login mode) for system users.Through CA figure certification and fingerprint equipment, the paper realizes the identification verification, rebuilds Zhongyuan oil field science and technology information management system, and realizes the function of automatic login and security attestation of the system. Users needn't remember the password. These not only guarantee the convenience of operation, but also increase security and dependability, and radically guarantee science and technology information...
