Abstract: Cloud Computing is a fast-growing area and its security issues block the prevalence widely in various areas; wherein the data protection is one of the critical/important among these. Guaranteed data protection is required to have data transfer from organizations to cloud for ensuring security in various aspects. Security is the primary concern in all areas of applications wherein still many challenges are there, even after proposing/recommending many techniques. Biometric is a most prevalent technique, which can be used in addressing these security issues. This paper enlightens about various biometric authentication methods available for cloud security, in which our research would be focusing on, by using any of the cryptographic methodologies.

Keywords: Cloud Security, Authentication, Biometrics, Identification, Verification.
