A majority of U.S. Internet users polled in a recent survey report taking steps to remove or mask their digital footprints online, according to a report from the Pew Research Center's Internet Project and Carnegie Mellon University. While 86 percent of the Internet users polled said they made some attempt hide what they do online, more than half of the Web users also said they have taken steps to avoid observation by organizations, specific people or the government, according to the survey.
