  1. Privacy Through Anonymous Connection and Browsing By: Abdelhamid Elgzil Advisor: Dr. Chow

  2. Outline • Introduction • The Problem • The Issue of Privacy and Anonymity • TOR: The Onion Router Network • VPN: Virtual Private Network • Challenges and Controversy • Conclusion • Potential Research and Future Work Privacy Through Anonymous Connection and Browsing

  3. 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. 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 Privacy Through Anonymous Connection and Browsing

  5. 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 Privacy Through Anonymous Connection and Browsing

  6. 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 Privacy Through Anonymous Connection and Browsing

  7. 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 Privacy Through Anonymous Connection and Browsing

  15. Challenges and Controversy • Criminals could take advantage • Anonymizersaren’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 Privacy Through Anonymous Connection and Browsing

  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 Privacy Through Anonymous Connection and Browsing

  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 Privacy Through Anonymous Connection and Browsing

  18. 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 Privacy Through Anonymous Connection and Browsing

  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) Privacy Through Anonymous Connection and Browsing
