Secure service to prevent data breaches in cloud

Cloud Computing is a computing paradigm shift where computing is moved away from personal computers or an individual server to a cloud of computers. Its flexibility, cost-effectiveness, and dynamically re-allocation of resources as per demand make it desirable. At an unprecedented pace, cloud computing has simultaneously transformed business and government, and created new security challenges such as data breaches, data loss, account hijacking and denial of service. Paramount among these security threats is data breaches. The proposed work is to prevent data breaching threat by way of providing user authentication through one-time password system and challenge response, risk assessment to identify and prevent possible risks, encryption using enhanced elliptic curve cryptography where a cryptographically secure random number generation is used to make the number unpredictable, data integrity using MD5 technique, and key management. The platform for deployment of the application is Google App Engine.
