Internet privacy involves the right or mandate of personal privacy concerning the storing, repurposing, providing to third-parties, and displaying of information pertaining to oneself via the Internet.
Privacy can entail either Personally Identifying Information (PII) or non-PII information such as a site visitor’s behavior on a website. PII refers to any information that can be used to identify an individual. For example, age and physical address alone could identify who an individual is without explicitly disclosing their name, as these two factors are unique enough to typically identify a specific person.
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. Internet and digital privacy are viewed differently from traditional expectations of privacy. Internet privacy is primarily concerned with protecting user information. Law Professor Jerry Kang explains that the term privacy expresses space, decision, and information.
