Cloud Computing is taking popularity day by day in a various organization as it provides giant and scalable space for public and private use. Cloud computing is now widely used by many of the organization as a service. With the increase in the usage of the cloud, there also increases the concerns of cloud security. Somehow many organizations are hesitating to keep their data in the cloud due to security concerns. This paper understands various security issues related to cloud and resolves the data security issues, based on our proposed framework. Proposed framework is based on securing the various types of data like text, image and videos by applying Encryption Algorithms which reduces the various security issues and loopholes and thus making it more secure. It prevents the data from unauthorized access and also maintains the CIA (Confindentiality , Integrity, Availability). The paper proves to be providing the security in least time.
