Abstract
Rapid development of information technology in education not only leads to great changes in the field of education, but also results in some security risks. How to ensure the safety of teaching resources has become a hot topic in current research in the teaching system with the cloud-terminal integrated digital classroom as scene. In the paper, importance of identity authentication mechanism is proposed by analyzing defects of cloud computing firstly, multiple identity authentication technologies are adopted for privacy protection of data. Features of four technologies, password authentication, smart card authentication, USB key authentication and biometric authentication, are analyzed in details. A set of multiple identity authentication system is designed and realized. The system is designed in Detailed system architecture is designed in the system for improving dynamic password technology and fingerprint recognition technology for ensuring data operation of legitimate users. Mobile terminals should be combined as example, and actual test can be conducted aiming at account recovery, remote data destruction and other demand after unexpected loss of smart terminal equipment. The result shows that the system can ensure accuracy and reliability of account and hardware equipment with excellent test effect.
