The Internet was originally created with one goal in mind; exchange information. This purpose has completely been manifested today, as we have so many avenues with which to share information. One person might get a funny email, and wishing to show it to all of his friends rather than poorly act it out and ruin the humor, can simply forward the document to everyone in his or her address book online. Many media sites like Youtube are completely based around this sharing principle. The videos you put on there can be seen by anyone, and whether your dance was really good or just completely awful, all one has to do is hit a button and the video is being sent to everyone on their email list. While these are all legal and easy ways to share content while online, many people have invented more insidious means to violate user contracts and copyrighting laws. If you search a popular music video on YouTube, you will probably find some random user who has uploaded it, which is in direct violation of YouTube’s user contract, and will probably be taken down quickly. People also can put songs up on the Internet for others to listen to and download; which is also illegal. There is a new kind of sharing though, called P2P (or Peer-to-Peer) that has law makers scratching their heads.

While uploading a copyrighted video is obviously a direct violation of the artist’s rights, is sharing one with a friend? If you buy a CD and your friend wants to hear it as well, should they have to pay to listen to your copy? The answer to this is for most people a resounding no. Then why are these P2P networks being so scrutinized? The problem is, they create digital copies of the songs, which can them be dispersed online for free, and completely ripping off the artist. This is the problem, but shutting down these good natured P2P networks is not in the cards right now.

What needs to be discussed though is the danger these networks provide, and not just for the artist’s bank accounts. Since anyone can upload anything to these networks, there can be some shady activity going on. While YouTube is the principles, this conduit of media has active virus scans and would not allow that to happen anyway, a feature that maybe one percent of all P2P networks enjoy. This means that somebody could have titled something to read as what it really isn’t and could have laced a tracking or crashing virus onto the file to hook onto your computer.

P2P networks can be a godsend if used correctly, but beware of their risks. You can enjoy using them if you just adequately protect yourself when surfing one. An anonymous proxy can stop trackers from latching onto your connection by changing your IP address, which is the system most use to follow someone online. With your new IP address, no one will be able to stalk you online.

A cache system is storage of data that is saved to your computer every time you visit a site. When you access a site that the cache has stored data on, the site will be accessed more quickly because you cut out the middle man (the site) and load it directly from your hard drive. This will speed up browsing time, and allow some sites to even be viewed while offline using the cache! While you wouldn’t be able to interact with other users or post things, you could view the entire site while you aren’t even connected to the Internet.

Some people use these cache systems to help out with their P2P (peer-to-peer) transfers. This will store part of the data that needs to be transferred and copied, and will allow it to load much more quickly. The cache will also hold other data that will cause the Internet to be a faster place for users and allow more data to be transferred more quickly.

The cache also comes with some risks too. Anytime identifying data or browsing history is stored on your computer, you will have some sort of privacy issue. The less information you keep about yourself and your browsing habits on your computer and on the Internet, the safer and more anonymity you will enjoy. It is possible that a hacker could gain access to your data by using your IP address to hack into your computer. It is also possible to just steal your computer and get into your cache. It is one thing for your system to be physically stolen, but if a hacker could remotely access your computer and get all sorts of sensitive information and other browsing habits, it could be forever before you found out and tried to stop it, but by then the damage could be irreversible.

Privacy is a big part of today’s world. As people’s information and data become more and more sensitive, the need to keep it hidden becomes more and more necessary. Ten years ago, someone’s IP address wouldn’t have been treated with any security what so ever, now it must be hidden at all costs. People probably wouldn’t have known what an IP address was at the time!

The demand for Internet privacy got to be so strong, that there began to be a market for it. People would pay for the services they provide, and would do so willingly. At first, these companies charged ridiculous amounts for their services, but today they are often dirt cheap.

Anonymous Proxy usage became more and more important. These are programs or web sites that actually alter your IP address, which is a virtual nametag showing location, browsing history, etc. The programs then allow you to surf on their encrypted networks to be sure all of your information is encoded upon you sending it. Then, they actually go and retrieve the websites you wish to visit for you, allowing you to bypass blocks set on work and school computers (or possibly an oppressive government) and enjoy the sites you want to. They will allow no traces of data such as cookies or cache to stay on your computer, allowing no one to see your browsing session. All your employer or teacher would see is the name of the anonymous proxy over and over and over again. If this isn’t good enough for you, professional fee-based proxies offer a “delete session information” function that completely deletes history of your browsing for that session, leaving no traces anywhere.

There are two major types of proxies; a software based proxy and a web based proxy. We’ll focus on the web based one first.
