Privacy protection in cloud-A three stage model

Cloud computing involves storage of data, computing in cloud and providing the services to the end user eliminating the need for maintenance of complex system in user premises. With the popularity of cloud computing, the need for multilevel security of data is of prime importance. This paper describes a 3-stage authentication system designed for the system. This system provides authentication using password protection, face recognition and voice recognition. Our system of voice recognition uses the recognition engines like CMU Sphinx and Julius and APIs, including Google Speech Engine, Google Cloud Speech API. For face recognition, a program using python script matches the face with an array of the sample images of the authorized person stored in the database. This provides a very robust authentication system and secures data from any hacking or unauthorized uses.
