TOR (The Onion Routing) is a free tool that allows anonymous use of the internet. It was developed by the US Naval Research Laboratory. TOR anonymizes internet traffic by routing it through several volunteer relays run by the TOR network, encrypting the traffic layer by layer and preventing others from seeing the user's IP address. Various groups use TOR including normal users, journalists, activists and law enforcement to maintain anonymity online, though the final link in the routing is not encrypted and slow network speeds are a limitation. Proper security measures must be taken when using TOR to ensure privacy is maintained.

 Introduction
 How it works?
 Who is uses TOR?
 How to use?
 Security concerns and consideration

3. Introduction :
 TOR(The Onion Routing)
 A free tool that allows people to use the
internet anonymously
 TOR anonymizes the origin of your traffic
 You can also host websites anonymously
 Developed by US navel research laboratory

4. How it works ? :
 Normal Network transaction
 User can be monitored
 Your IP address can be seen

5. Network transaction using TOR network
 No of relays are present
 Your IP address can’t be seen.
 IP address of last relay will be seen by others.
 Traffic is encrypted in network.
 A relay only knows up and down stream relay it is
connected to.
 Route for transactions changes after few minutes.

6. Who uses TOR ? :
 Normal people
 Militaries
 Journalists and their audience
 Law enforcement
 Activists
 Bloggers
 IT professionals

7. How to use ? :

11. Security concerns and considerations :
Final link is not encrypted
Grabbing information before getting passed into the network
computer is infected with spyware, malware or key logger
Don’t use multiple networking tools at the same time
Slow network speed
Illegal use

12. Conclusion :
TOR can be use to maintain the
anonymity of a person but we have to
remember that TOR is tool like other tools and
can be manipulated like other technology
tools. So you must use multiple layers of
security in order to make sure that your
privacy is kept.
