ABSTRACT
Offering strong data protection to cloud users while enabling rich applications is a challenging task. We explore a new cloud platform architecture called Data Protection as a Service, which dramatically reduces the per-application development effort required to offer data protection, while still allowing rapid development and maintenance.
EXISTING SYSTEM
Cloud computing promises lower costs, rapid scaling, easier maintenance, and service availability anywhere, anytime, a key challenge is how to ensure and build confidence that the cloud can handle user data securely. A recent Microsoft survey found that “58 percent of the public and 86 percent of business leaders are excited about the possibilities of cloud computing. But more than 90 percent of them are worried about security, availability, and privacy of their data as it rests in the cloud.”
PROPOSED SYSTEM
We propose a new cloud computing paradigm, data protection as a service (DPaaS) is a suite of security primitives offered by a cloud platform, which enforces data security and privacy and offers evidence of privacy to data owners, even in the presence of potentially compromised or malicious applications. Such as secure data using encryption, logging, key management.
Advantages
1. When you use internet with the cloud services then your company will have lots more room to store the files and that they need to store.
2. User identified the data losses.
Disadvantages
1. Bulk Data Transfers: Bringing a lot of data into or out of a cloud instance takes a good deal of time. Without a high-capacity connection, it could take days to load all that data.
2. Dependency (loss of control): Quality problems with CSP (Cloud Service Providers).No influence on maintenance levels and fix frequency when using cloud services from a CSP
Cloud Computing
Cloud computing is the provision of dynamically scalable and often virtualized resources as a services over the internet Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them. Cloud computing represents a major change in how we store information and run applications. Instead of hosting apps and data on an individual desktop computer, everything is hosted in the "cloud"—an assemblage of computers and servers accessed via the Internet.
CONCLUSION
As private data moves online, the need to secure it properly becomes increasingly urgent. The good news is that the same forces concentrating data in enormous datacenters will also aid in using collective security expertise more effectively. Adding protections to a single cloud platform can immediately benefit hundreds of thousands of applications and, by extension, hundreds of millions of users. While we have focused here on a particular, albeit popular and privacy-sensitive, class of applications, many other applications also needs solutions.
