BIOMETRIC MODALITIES
Biometric modalities include fingerprint, face, iris, voice, signature and hand geometry etc..
Implementing a biometric device including location, security risks etc..

FACE RECOGNITION
Predominant Approaches :
Principal Components Analysis (PCA).Linear Discriminant Analysis (LDA).Elastic Bunch Graph Matching (EBGM).

PCA: Principal Components Analysis
Standard Eigenfaces: Feature vectors are derived using Eigenfaces.

CONCLUSION
Biometrics provides high security and reduces the incidence of unauthorized access in sensitive areas.
Biometrics cannot be lost, stolen or forgotten.
More secure than a long password.
