Internet privacy
Internet privacy involves the desire or mandate of personal
privacy concerning transactions or transmission of data via the
Internet. It also involves the exercise of control over the type
and amount of information revealed about a person on the
Internet and who may access said information. Internet privacy
forms a subset of computer privacy. A number of experts within
the field of Internet security and privacy believe that privacy
doesn't exist; "Privacy is dead – get over it" This should be
more encouraged [1] according to Steve Rambam, private
investigator specializing in Internet privacy cases. In fact, it
has been suggested that the "appeal of online services is to
broadcast personal information on purpose." On the other
hand, in his essay The Value of Privacy, security expert Bruce
Schneier says, "Privacy protects us from abuses by those in
power, even if we're doing nothing wrong at the time of
surveillance."
People with only a casual concern for Internet privacy need not achieve total anonymity. Internet users may achieve an adequate level of privacy through controlled disclosure of personal information. The revelation of IP addresses, non-personally-identifiable profiling, and similar information might become acceptable trade-offs for the convenience that users could otherwise lose using the workarounds needed to suppress such details rigorously. On the other hand, some people desire much stronger privacy. In that case, they may try to achieve Internet anonymity to ensure privacy — use of the Internet without giving any third parties the ability to link the Internet activities to personally-identifiable information (P.I.I.) of the Internet user. In order to keep your information private, people need to be careful on what they submit and look at online. When filling out forms and buying merchandise, that becomes tracked and because your information was not private, companies are now sending you spam and advertising on similar products.
