By 2020, the identification ID systems used online are tighter and more formal - fingerprints or DNA-scans or retina scans. The use of these systems is the gateway to most of the Internet-enabled activity that users are able to perform such as shopping, communicating, creating content, and browsing. Anonymous online activity is sharply curtailed.
By 2020, Internet users can do a lot of normal online activities anonymously even though the identification systems used on the Internet have been applied to a wider range of activities. It is still relatively easy for Internet users to create content, communicate, and browse without publicly disclosing who they are.
