One measure of this is how many people are using DuckDuckGo, a search engine that promises a higher level of security. As Google, Microsoft, and others have been implicated in turning people’s search terms over to spy agencies, not to mention commercial interests, DuckDuckGo has seen traffic levels jump. DuckDuckGo still keeps a record of searches and analyzes what the public is paying attention to, but it does so without trying to tie searches to people and places. http://www.computerworld.com.sg/resource/internet/meet-the-search-engine-that-vows-not-to-track-you/
