What about privacy on the Internet?
How much should one reveal or share one's personal life virtually? What are the consequences of having personal information exposed and vulnerable in cyberspace without knowing it? Individuals and organizations that have sensitive data now face many concerns and challenges. Information privacy or data privacy is the relationship between collection and dissemination of data, technology, the public expectation of privacy, and the legal and political issues surrounding them. When sharing data, we also face the challenge of data or information security.
Privacy software can help to protect the privacy of its users. The software works in conjunction with Internet usage to control or limit the amount of information made available to third-parties by applying encryption or filtering of various kinds. There are two different types of protection the software can provide: 1.Protecting a user's Internet privacy from the World Wide Web. Some software products can mask or hide a user's IP address from the outside world in order to protect the user from identity theft. 2.Hiding or deleting the users Internet traces that are left on their PC after they have been surfing the Internet. There is software that will erase all the users Internet traces and there is software that will hide and encrypt a user's traces so that others using their PC will not know where they have been surfing. Using encryption and anonymizers may help.
Encryption uses algorithm to make information unreadable to those who do not have knowledge about the "key." The encrypted information (or "cyphertext")can be unencrypted or made readable again (a process called "decryption"). Encryption helps secure data both at rest and in transit from physical security failure, and from unauthorized use or reproduction. It also helps to protect confidentiality and authenticity of messages. However, encryption application and products may not work properly in every case.
Anonymizer is a proxy server computer that acts as an intermediary shielding a client computer from the rest of the Internet. Anonymizers serve many purposes, from minimizing risks (e.g., identity thefts)to bypassing web technology (to get access to prohibited sites). Anonymizers can be implemented with one specific protocol, through connection with an independent protocol, or through relays in a network (e.g., the Tor network)
