A Study of Different Biometric Authentication Techniques in Cloud Computing

Cloud computing is a new technology, which is rising rapidly in the market. In cloud computing many computers and servers are connected and are accessed via internet. Using cloud computing we access data, files, resources, application software, operating systems, databases, web servers etc. from anywhere at any time via internet. Cloud computing gets more work done in less time, with less people and with shared hardware and software. So, it gives great throughput with reduce cost. As cloud computing is based on sharing, it is necessary to allow only authorized users in cloud. In short, security is major concern in cloud computing. For authentication different traditional and biometrics techniques are used. Traditional techniques like password, OTP are easily attackable. So, researchers move to biometric techniques. Biometric techniques are more secure as it depends upon physiological and behavioral characteristics of user. This paper is a brief overview of different biometric authentication techniques used in cloud computing with their proposed methods and advantages.
