Abstract: This paper researches on electronic authentication in cloud computing and analyzes the deficiencies of mainstream authentication methods. We propose a more accurate and secure authentication solution using behavior and active privileges recognition technology. This solution can implement behavior-based active privileges recognition and choose adaptively whether to use high-strength safety certification. It also prevents hacking effectively and reduces the threats on security Certification.
