This document discusses fog computing and a proposed system to improve security of data stored in the cloud. It proposes using decoy technology to monitor for abnormal access patterns and generate fake documents to confuse attackers. The system would profile user behavior to validate authorized access and deploy decoys when abnormal access is detected. This helps prevent attackers from distinguishing real user data from fake data.

3. ABSTRACT
Fog computing is not a replacement of cloud it is just extends
the cloud computing by providing security in the cloud
environment.
Cloud computing promises to significantly change the way of
use computers and store our personal and business information
can arises new data security challenges. Encryption
mechanisms not protect the data in the cloud from unauthorized
access.
 We proposed a different approach for securing data in the cloud
using offensive decoy technology. We monitor data access in
the cloud and detect abnormal data access patterns.

4. EXISTING SYSTEM
 In Existing data protection mechanisms such as encryption was
failed in securing the data from the attacker. It does not verify
whether the user was authorized or not.
 Cloud computing security does not focus on ways of secure the
data from unauthorized access.
In 2009 we have our own confidential documents in the cloud.
This file does not have much security. so, hacker gains access
the documents. Twitter incident is one example of a data theft
attack in the Cloud.

5. DISADVANTAGES
No body is identified when the attack is happen.
It is complex to detect which user is attack.
We can not detect which file was hacking.

6. PROPOSED SYSTEM
We proposed a completely new technique to secure user’s
data in cloud using user behavior and Decay information
technology called as fog computing.
 In this technique when the unauthorized person try to access
the data of the real user the system generates the fake
documents in such a way that the unauthorized person was
also not able to identify the data is fake or real

7. USER BEHAVIOR PROFILING
Admin monitor data access in the cloud and notice
abnormal data access patterns User profiling will a well
known Technique that can be applied here to check
how, when, and how much a client access their data in
the Cloud.
 This method of behavior based security will regularly
used in scheme uncovering applications.

8. DECOY SYSTEM
We suggest a different approach for securing data in
the cloud using nasty decoy technology.
 We monitor data access in the cloud and sense
irregular data access patterns.
We use this technology to begin disinformation
attacks against malicious insiders, preventing them
from distinguishing the valid aware customer data
from bogus useless.

9. DECOY SYSTEM

10. DECOY SYSTEM ADVANTAGES
The decoys, then, serve two purpose
Validating whether data access is authorized when
abnormal information access is detected.
 Confusing the attacker with bogus information

11. ARCHITECTURE

12. CONCLUSION
The system was developed only with email provision
but we have also implemented the SMS technique. In
Fog Computing we presenting a new approach for
solving the problem of insider data theft attacks in a
cloud using dynamically generated decoy files and also
saving storage required for maintaining decoy files in
the cloud. So by using decoy technique in Fog can
minimize insider attacks in cloud..

13. FUTURE SCOPE
In our future work, this security system as we have
explained is applicable only for single cloud ownership
system. If the cloud owner has a more than one clouds to
operate then our security system will not be applicable for
providing security, therefore in the future enhancement
we can enhance our existing application to manage a
cloud environment which has more than one cloud
architecture.
 Cloud computing is the future for organizations.
