3. Privacy Through Anonymous Connection and Browsing
Introduction
Privacy and Anonymity are becoming a big concern for individuals and organizations
Examine two technologies:
The Onion Router (TOR) project for anonymous and security browsing by connecting through a series of virtual tunnels
Virtual Private Network (VPN) to maintain privacy through the use of a tunneling protocol and security procedures

Privacy Through Anonymous Connection and Browsing

4. Privacy Through Anonymous Connection and Browsing
The Problem
Concern about improving privacy and security on the Internet
Looking for new communication tools
Built-in privacy features
Help share information over public networks without compromising user’s privacy
Protect user privacy while browsing the internet, to get connected to news sites, or avoid geo-blacking
Help publish web sites and other services without exposing the location of the site
Supporting socially sensitive communication
Protecting against traffic analysis
Source and destination information can lead to track the user behavior and interests, even connection is encrypted

List of the concrete concerns. Express political opions in oppressive government
Geo-blacking?
This is more a requirements not problem.

Privacy Through Anonymous Connection and Browsing

5. Privacy Through Anonymous Connection and Browsing
The Problem
TOR offers browsing anonymous
TOR does not guarantee a complete anonymity
Focus only on protecting the transfer of data
User might need to use specific software to prevent the visited sites from revealing his identity information
VPN is an Additional layer of protection
Gain an tightened anonymity protection
Hiding using of TOR as a communication tool
Enable TOR use in geo-blocked regions
Title -> TOR vs. VPN
Need separate viewgraphs. Show a topology or components.
Perhaps we should wait until TOR and VPN is introduced.
Forward references.

6. Privacy Through Anonymous Connection and Browsing
Privacy and anonymity
Two different thoughts
Both progressively essential as we get increasingly monitored and tracked
Privacy  Ability to keep some things to yourself
Regardless of their impact to society
Anonymity  Desire to want people to see what you do, just not that it’s you doing it
Anonymity extremely effective in promoting freedom of expression
These needs should be discussed before the means for delivering them. TOR or VPN

7. Privacy Through Anonymous Connection and Browsing
Privacy and anonymity
The degree of privacy mostly linked to:
Type of encryption utilized
Computational capacity avail- able
In some circumstances, threats against privacy and anonymity happen due to the absence of proper technology  unintentionally
Bugs, ISP
Non-educated users

15. Challenges and Controversy
Criminals could take advantage
Anonymizers aren’t foolproof
First and last routers are malicious or compromised
OSP publish enough information about their workings, including node addresses
Governments or other organizations block traffic
Some single-proxy anonymizer services may log users’ IP addresses
Be specific about specific papers. These

16. Challenges and Controversy
Providing greater security VS. Performance
Additional proxies and encryption increase overhead
Performance overhead causes anonymization to slow users’ Internet access
ISPs block nodes to control spam
They block those used by anonymizers
Browser complexity and the need to maintain browsing functionality could help proficient hackers sidestep anonymization
Last bullet does not make sense. Cite where it is comes from. Sidestep anonymization mean defeat anonymizatoin.

17. Challenges and Controversy
Cultural and legal challenges
Legal challenge Some countries outlawing or could decide to prohibit the use of privacy tool
They require all Internet providers to keep detailed access records
The cultural issue The trend toward [openness on the Internet]
The desire to privacy and Anonymous communication will drive the technology’s continued development and adoption
Think Two or three things to help with legal/culture challenges.

18. Privacy Through Anonymous Connection and Browsing
Conclusion
Privacy and security are interconnected
Almost impossible to achieve one without the other
People and organizations need to have some level of anonymity
Anonymity can be abused by some people, but should not be an excuse
Privacy and anonymity are important in today’s information technology driven world
Today, users aware of privacy and anonymity impacts
This will have positive economic outcomes
There is very little technical details (facts/solutions/techniques; both attacks and defense sides) in your presentation

19. Potential Dissertation Research Tasks
Create TOR Emulator by leveraging Software-defined networking (SDN)
Enhance packet marking techniques to efficiently trace the packet path within TOR network
How to utilize SDN controller in cloud to detect the using of VM as a TOR relay, by analyzing the characteristics of TOR relay in virtualized environment
Using TOR bridges or TOR proxy to hide the intention to connect to TOR (prevent others to detect your using of TOR)
Add SDN slide before.
For each task, ask why you need to carry out this tasks.
What packet marking techniques you try to create? What aspect they are not good.
Using SDN controller to detect or to avoid detection of using VM as TOR relay will be a task.
Define TOR bridges/proxy in previous slides.
What all these four tasks/ research contribution will bring.
