Availability, scalability, and security are the main concerns in a cloud environment and so it undergoes various challenges in the availability and security of sensitive and critical data stored in it. Multifactor authentication is one solution that offers layered defence in order to perform verification and validation of the users' credentials that makes it difficult for an adversary to access the data stored in the cloud. This paper addresses the security issues in the cloud environment by suggesting a multifactor authentication model that utilises three significant factors such as static authentication, click colour-based dynamic authentication and behavioural biometrics specifically keystroke with cryptographic encryption and hashing technique. Based on the experimental results, it is clear that the proposed method verifies and validates the authorised users thereby eliminating the adversaries with more than 96% of accuracy. Also, the model decreases the false positive and error rate to an extent of 3%.
