PROBLEM STATEMENT
• Dealing with “single cloud” providers is predicted to become
less popular with customers due to risks of service availability
failure and the possibility of malicious insiders in the single
cloud.
• A movement towards “multi-clouds”, or in other words,
“interclouds” or “cloud-of-clouds” has emerged recently.

WHAT IS CLOUD
COMPUTING ?
• Cloud computing is a model for enabling ubiquitous(present),
convenient, on-demand network access to a shared pool of
configurable computing resources (e.g., networks, servers,
storage, applications, and services) that can be rapidly
provisioned and released with minimal management effort or
service provider interaction.
• This cloud model is composed of five essential characteristics,
three service models, and four deployment models.

DEPLOYMENT MODELS

DIFFERENCE BETWEEN TRADITIONAL DATA
CENTER AND CLOUD COMPUTING SERVICES
 Traditional Data Services:-
-Proprietary Customize
-More Secure
-Economy of Scale: Organization
-Dedicated
 Cloud Computing Services:-
-Standardized
-Secure
-Economy of Scale: Ecosystem
-Share

MOVING TO CLOUDS
• Data is moving to the cloud
• Main reason: costs (pay-per-use model)

EVERYTHING
CONNECTED TO CLOUD

EXISTING SYSTEM
• Cloud providers should address privacy and security issues as a
matter of high and urgent priority.
• Dealing with “single cloud” providers is becoming less popular
with customers due to potential problems such as service
availability failure and the possibility that there are malicious
insiders in the single cloud.
• Byzantine Protocol

IF IT FAILS…?

DISADVANTAGES OF
EXISTING SYSTEM
 Cloud providers should address privacy and security issues as a
matter of high and urgent priority.
 Service availability failure and the possibility that there are
malicious insiders in the single cloud.

CLOUD SECURITY

PROPOSED SYSTEM
• This Project focuses on the issues related to the data security
aspect of cloud computing.
• Moving towards “Cloud of clouds “ or multi clouds technique
which improves
Better read performance
Data corruptions'
Reduces Intrusions ….etc

MULTI CLOUDS

ADVANTAGES OF
PROPOSED SYSTEM
 DepSky System:Multicloud model
 Shamir’s Secret sharing algorithm
 The user runs custom applications using the service provider’s
resources
 Cloud service providers should ensure the security of their
customers’ data and should be responsible if any security risk
affects their customers’ service infrastructure.

IMPLEMENTATIONS
MODULES
 Data Integrity
 Data Intrusion
 Service Availability
 DepSKy system model

DEPSKY ADRESSES THREE
IMPORTANT LIMITATIONS
 Loss of availability
 Loss and corruption of data
 Loss of privacy

CONCLUSION
• It is clear that although the use of cloud computing has rapidly
increased, cloud computing security is still considered the major
issue in the cloud computing environment.
• Customers do not want to lose their private information as a
result of malicious insiders in the cloud. In addition, the loss of
service availability has caused many problems for a large
number of customers recently

FUTURE ENHANCEMENTS
 For future work, we aim to provide a framework to supply a
secure cloud database that will guarantee to prevent security
risks facing the cloud computing community.
 This framework will apply multi-clouds and the secret sharing
algorithm to reduce the risk of data intrusion and the loss of
service availability in the cloud and ensure data integrity.
