This project presentation summarizes a proposed algorithmic approach to cloud data security. The presentation was given by students Gaurav Shukla, Rishank Kesarwani, and Hera Neyaz to their computer science professor. It outlines the objective to resolve cloud security issues, motivation due to increasing cloud usage and data breaches. A proposed model is described using data flow diagrams to encrypt text, image, and video data before storing in the cloud. Challenges for attackers to locate, access, and gather information about encrypted data are also discussed. The project roadmap and conclusions state that the approach provides double security for easy-to-access cloud data storage while ensuring data retrievability.

3. INTRODUCTION
According to AT & T , Cloud is
Common
Location-independent
Online
Utility
available on-Demand service.
 Cloud Computing is internet-based computing where shared resources,software and information are
provided to the computer.
 It promises not just cheaper IT,but also faster,easier,more flexible,and more effective IT. It is also
versatile and flexible application of internet.
 Consider an example of Hotmail.com,Yahoo.com or Gmail.com where no installation of server or
softwares is required. All you need to access them is an internet connection. These are simple examples
of cloud computing.

4. OBJECTIVE
 The objective is to resolve the various security issues related to cloud .
 The cloud can be used by any user of any age group with ease of access.
 The contribution made by this project will enable the people and
organizations to secure their data in more effective way.

5. MOTIVATION
 Internet is the foremost thing which we all require in this generation.
 Data is considered as Money in the 21st Century so it need to be secured.
 60% of IT Market Growth Is Being Driven By The Cloud.According to
Wikibon’s report cloud spending is growing at a 16% Compound annual
growth(CAGR) run rate between 2016 and 2026.
 Breach level index also reports that out of the 5.9 billion records that have
been lost or stolen since 2013 only 4% consisted of encrypted data which is
useless to any hacker.

6. CLOUD SERVICE MODELS
 There are two types of Cloud Services Models.
1. Delivery Models
a. SaaS
b. Paas
c. Iaas
2. Deployment Models
a. Public
b. Private
c. Hybrid
d. Community Cloud

7. Why do we need Cloud Data Security?
 Data breaches happen every day
 Cyber Attacks Are On The Rise
 Controlled Access
 Managing the CIA(Confidentiality,Integrity,Availability)

8. PROBLEM DEFINITION
 Breach level index reports that out of the 5.9 billion records that have been
lost or stolen since 2013 only 4% consisted of encrypted data which is useless
to any hacker.
 According to the Privacy Rights Clearinghouse report, data based on the
amount of data lost, databases are the major source (64%) of data loss.
Interest in the cloud is increasing day by day.
 60% of IT Market Growth Is Being Driven by the Cloud. According to Wikibon’s
report, cloud spending is growing at a 16% Compound annual growth (CAGR)
run rate between 2016 and 2026.

14. Challenges For Attacker:
 How to find out where the target is located?
 How to be co-located with the target within the same
(physical) machine?
 How to gather information about target?

15. DESIGN
1. TEXT DATA

16. 2. IMAGE DATA

17. 3. VIDEO DATA

18. RESULTS
1. TEXT DATA

19. 2. IMAGE DATA
BEFORE ENCRYPTION AFTER ENCRYPTION

20. Roadmap to Complete Project
 Phase 1: Literature Review
 Phase 2: Division of Task
 Phase 3: Working on Our Proposed Model
 Phase 4: Implementation of Our Proposed Model
 Phase 5: Final Verification

21. Conclusion
 This project proposes a Security model to improve security of cloud Data
 Through our approach, the cloud provider cannot directly reach the data.
This technique provides double security to the data stored in cloud and it
is easy to integrate, that defends malicious activities occurred on the cloud
server.
 It also ensures data retreivability.
 Distribution of data ensures security of sensitive data.
