Analysis of Internet Users’ Level of Online Privacy Concerns

Statements about privacy can be either descriptive or normative,depending on whether they are used to describe the way people definesituations and conditions of privacy and the way they value them, orare used to indicate that there ought to be constraints on the use ofinformation or information processing. Informational privacy in anormative sense refers typically to a non-absolute moral right ofpersons to have direct or indirect control over access to (1)information about oneself, (2) situations in which others couldacquire information about oneself, and (3) technology that can be usedto generate, process or disseminate information about oneself.

Some special features of Internet privacy (social media and BigData) are discussed in the following sections.

A growing number of software tools are available that provide someform of privacy (usually anonymity) for their users, such tools arecommonly known as privacy enhancing technologies (Danezis &Gürses 2010, Other Internet Resources). Examples includecommunication-anonymizing tools such as Tor (Dingledine, Mathewson,& Syverson 2004) and Freenet (Clarke et al. 2001), andidentity-management systems for which many commercial softwarepackages exist (see below). Communication anonymizing tools allowusers to anonymously browse the web (with Tor) or anonymously sharecontent (Freenet). They employ a number of cryptographic techniquesand security protocols in order to ensure their goal of anonymouscommunication. Both systems use the property that numerous users usethe system at the same time which provides -anonymity (Sweeney2002): no individual can be uniquely distinguished from a group ofsize , for large values for . Depending on the system,the value of can vary between a few hundred to hundreds ofthousands. In Tor, messages are encrypted and routed along numerousdifferent computers, thereby obscuring the original sender of themessage (and thus providing anonymity). Similarly, in Freenet contentis stored in encrypted form from all users of the system. Since usersthemselves do not have the necessary decryption keys, they do not knowwhat kind of content is stored, by the system, on their owncomputer. This provides plausible deniability and privacy. The systemcan at any time retrieve the encrypted content and send it todifferent Freenet users.

The Internet, originally conceived in the 1960s and developed inthe 1980s as a scientific network for exchanging information, was notdesigned for the purpose of separating information flows (Michener1999). The World Wide Web of today was not foreseen, and neither wasthe possibility of misuse of the Internet. Social network sitesemerged for use within a community of people who knew each other inreal life—at first, mostly in academic settings—ratherthan being developed for a worldwide community of users (Ellison2007). It was assumed that sharing with close friends would not causeany harm, and privacy and security only appeared on the agenda whenthe network grew larger. This means that privacy concerns often had tobe dealt with as add-ons rather than by-design.

A major theme in the discussion of Internet privacy revolves aroundthe use of cookies (Palmer 2005). Cookies are small pieces of datathat web sites store on the user's computer, in order to enablepersonalization of the site. However, some cookies can be used totrack the user across multiple web sites (tracking cookies), enablingfor example advertisements for a product the user has recently viewedon a totally different site. Again, it is not always clear what thegenerated information is used for. Laws requiring user consent for theuse of cookies are not always successful, as the user may simply clickaway any requests for consent, merely finding themannoying. Similarly, features of social network sites embedded inother sites (e.g., “like”-button) may allow the socialnetwork site to identify the sites visited by the user (Krishnamurthy& Wills 2009).
