Proposed Data Security Model for Cloud Computing

ABSTRACT From the perspective of data security, which has always been an important aspect of quality of service, Cloud computing focuses a new challenging security threats. Therefore, a data security model must solve the most challenges of cloud computing security. The proposed data security model provides a single default gateway as a platform. It used to secure sensitive user data across multiple public and private cloud applications, including salesforce, Chatter, Gmail, and Amazon Web Services, without influencing functionality or performance. In our paper we proposed the data security model doing that the person authorized third parties, if he wants to enter the data in the cloud illegally, will face multiple aspects of security, electronic signature first, the second hiding this signature in digital file image, thirdly encryption the data storage in clouding computing stage byusing Multiprime PublicKey method .
