Along with various understandings of privacy, there are actions that reduce privacy, the most recent classification includes processing of information, sharing information, and invading personal space to get private information, as defined by Daniel J. Solove. Conversely, in order to protect a user's privacy, multiple steps can be taken, specifically through practicing encryption, anonymity, and taking further measures to bolster the security of their data. History Privacy has historical roots in ancient Greek philosophical discussions. The most well-known of these was Aristotle's distinction between two spheres of life: the public sphere of the polis, associated with political life, and the private sphere of the oikos, associated with domestic life. In the United States, more systematic treatises of privacy did not appear until the 1890s, with the development of privacy law in America. Technology As technology has advanced, the way in which privacy is protected and violated has changed with it. In the case of some technologies, such as the printing press or the Internet, the increased ability to share information can lead to new ways in which privacy can be breached. It is generally agreed that the first publication advocating privacy in the United States was the 1890 article by Samuel Warren and Louis Brandeis, "The Right to Privacy", and that it was written mainly in response to the increase in newspapers and photographs made possible by printing technologies. In 1948, 1984, written by George Orwell, was published. A classic dystopian novel, 1984 describes the life of Winston Smith in 1984, located in Oceania, a totalitarian state. The all-controlling Party, the party in power led by Big Brother, is able to control power through mass surveillance and limited freedom of speech and thought. George Orwell provides commentary on the negative effects of totalitarianism, particularly on privacy and censorship. Parallels have been drawn between 1984 and modern censorship and privacy, a notable example being that large social media companies, rather than the government, are able to monitor a user's data and decide what is allowed to be said online through their censorship policies, ultimately for monetary purposes. In the 1960s, people began to consider how changes in technology were bringing changes in the concept of privacy. Vance Packard's The Naked Society was a popular book on privacy from that era and led US discourse on privacy at that time. In addition, Alan Westin's Privacy and Freedom shifted the debate regarding privacy
