The document discusses cloud computing, highlighting its benefits such as lower costs and accessibility, but also notes concerns about security and privacy among users. It proposes a new system called Data Protection as a Service (DPaaS) that aims to enhance data security through access control, logging, and auditing. The conclusion emphasizes the importance of protecting cloud users' data and ensuring secure execution environments.

2. Cloud Computing
Cloud computing provides lower costs, rapid
scaling, easier maintenance, and services that are
available anywhere, anytime.
A recent Microsoft survey-
 58% of the public and 86% of business leaders.
 90% of them are worried about security,
availability, and privacy .

4. Existing system
 Software as a Service (SaaS)
 Platform as a Service (PaaS)
 Infrastructure as a Service (IaaS)

5. Disadvantages
CSPs believe that Security is End-users’ Issue.
Inconsistent Network Connection Issues.
Clients have no idea or control over what happens
inside a cloud.

6. PROPOSED SYSTEM
 Data Protection as a Service (DPaaS).
 Provides a common platform for masses.
 Access control, logging and key management.
 Auditing of data protection.

11. Advantages
Secure execution environment.
It reduce the effort of cloud service
providers .
Provides a common platform for
masses.
 Access control, logging and key
management.

12. Modules
 Cloud Computing
 Trusted Platform Module
 Third Party Auditor
 User Module

13. Key management
Advanced Encryption Standard (AES).
AES-128, AES-192 and AES-256.
Each cipher encrypts and decrypts data in
blocks of 128 bits using cryptographic keys of
128-, 192- and 256-bits.

14. Conclusion
Protect the data of cloud users and is part
of cloud computing.
 Provides complete security with the
help of access control, logging, and key
management
