4. Cloud Computing:
 Cloud computing is a distributed computing paradigm.
 Hardware and/or software infrastructure over the internet.
 Networked storage space and computer resources.
Why Cloud Computing:
 Your information from anywhere at any time.
 Cloud provider can both own and house the hardware and
software
 Run your home or business applications.

5. Types of Services provided by Cloud
Environment:
 Software as a Service (SaaS): The applications,
such as e-mail, people use everyday.
Platform as a Service (PaaS): The operating
environment in which applications run.
Infrastructure as a Service (IaaS): The on-
demand data centers.

6. Motivation:
 Currently, “cloud computing” is the most often used
buzzword in computing.
 Many Cloud providers emphasize many benefits of
outsourcing application into a cloud.
 A mature technology that is ready to be massively
used.
 Users’ fears of losing control of their own data can
become a significant barrier to the wide adoption of
cloud services.

7. Existing System:
◘ Using a centralized server in distributed environments.
◘ Data handling can be outsourced by the direct cloud
service provider (CSP).
◘ Entities are allowed to join and leave the cloud in a
flexible manner.
◘These entities can also delegate the tasks to others,
and so on.
◘ Data handling in the cloud goes through a complex and
dynamic hierarchical service chain

8. Proposed System:
☻ A novel approach, namely Cloud
Information Accountability (CIA) framework is
used.
☻ It focuses on keeping the data usage
transparent and trackable.
☻ Platform independent and highly
decentralized
☻ It does not require any dedicated
authentication or storage system in place.

10. Conclusion:
♫ This system enforce strong back-end
protection
♫ It enables the data owner to audit even those
copies of its data
♫ It also provides a detailed security analysis
and discuss the reliability and strength of our
architecture.
