A Comparative Study of Biometric Authentication in Cloud Computing.

Cloud computing has attracted businesses to move from the traditional way of sharing IT resources due to multiple factors including cost, productivity, performance, scalability and security. The benefits of cloud computing are enormous, but it is a complex technology needing complex protocols for human identification for specific applications over the network. Biometric authentication provides one of the promising methods for authentication in a cloud environment. This paper is a survey-based review that summarize the recent schemes used for biometric authentication in the cloud computing and highlights their pros and cons to find the best approach for this purpose. Result of this survey recommended that the multimodal biometric authentication improves and reduces its complexity and computation time with the use of Biometric-as-a-service (Baas).
