An Efficient Two - Factor Access Control For Web-Based Cloud Computing Services Using Jar File

Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services over the internet. This computing paradigm also conveys many new challenges for data security and access control. The users are outsourcing sensitive data for sharing on cloud servers, which are not within the same trusted domain as original data. To keep sensitive user data confidential against entrusted servers. Existing solutions usually apply cryptographic methods by disclosing data decryption keys only to authorize users. However, in this performance these solutions unoriginally introduce a heavy computation overhead on the sensitive data for key distribution and data management. These problems are not simultaneously achieving the data confidentiality of access control actually still remains unresolved. Analyzed how the existing schemes secure against the key-logger, shoulder-surfing attacks, and multiple attacks. The proposed system illuminates to implement the secret key using JAR file application instead device for web based access control protocol. Main purpose of the existing system to proposed system is complications in carrying the device to everywhere, to avoid non- accessibility through the physical damage and loss of the device. In the proposed system secret key is developed using JAR file application developed with blowfish algorithm scheme for encryption and decryption.
