A SURVEY ON BIOMETRIC AUTHENTICATION SYSTEMS IN CLOUD TO COMBAT IDENTITY THEFT

Biometrics has by far proven to be an effective solution for many of the security challenges that is prevalent in most of the technical fields
in this Digital era. It is the measurement of physical or behavioral traits in humans used for unique identification. Biometricsuses the
pattern recognition technology of Digital Image Processing for identifying unique features in humans. Most commonly applied or
considered biometric modalities comprise fingerprint impression, facial landmarks, iris anatomy, speech recognition, hand writing
detection, hand geometry recognition, Finger vein detection and signature identification. Biometric technology is applied in various fields, Security systems being one among them. This paper presents a thorough survey on how biometrics can be effectively applied to eliminate oneof the cloud security issue, identitytheft. Awide range of biometric authentication system protocols and implementations in cloud environment, especially to combat identity theft have been proposed earlier.
