Paper Title
A Survey on Various Biometric Approaches

Multi-biometrics is an exciting and motivating research topic. It's used to recognizing persons for security reasons; to amplify security levels. The present analysis inclined towards next biometrics generation in real-time applications. Additionally, combination of biometrics resolves a number of unimodal system inadequacies. On the other hand, design and assessment of such systems raises several issues and trade-offs. An up to date review of multi-biometrics benefits, restrictions, combination approach, and fusion levels are mentioned in this paper. At last, upon reviewing multi- biometrics strategies and approaches; some open points are suggested to be considered as a future research point of interest.
