As more and more technologies emerge, the impact of secure database systems on these technologies will be significant. An aid to control the suspicious login of the database and suspicious session is a must. Authentication is required when it is necessary to know if a person is who they claim to be. In this paper, the authors introduces the concepts of multimodal biometrics that integrates two or more biometric identifiers and takes advantage of the capabilities of each biometric to provide greater performance and higher reliability. It also discusses various levels of fusion, the importance of fusion at the feature level and a comparative study using different algorithms for performance analysis.
