MetaGer is a metasearch engine focused on protecting users' privacy. Based in Germany, and hosted as a cooperation between the German NGO 'SUMA-EV - Association for Free Access to Knowledge' and the University of Hannover,[2][3][4] the system is built on 24 small-scale web crawlers under MetaGer's own control. In September 2013, MetaGer launched, an English language version of their search engine.[5]

Search queries are relayed to as many as 50 search engines.[4][6] The results are filtered, compiled and sorted before being presented to the user. Users can select the search engines to query according to their individual choices among other options (such as "check for availability and sort by date").[7] Privacy protection is implemented by several features: MetaGer provides access to their services only through encrypted connections. As of December 2013, there is also a TOR Hidden Service (b7cxf4dkdsko6ah2.onion/tor/) that allows users to access the MetaGer search functionality from within the TOR network.[8][9][10] Since February 2014 MetaGer additionally offers the option to open the result webpages anonymously ("open anonymously").

Since the 29th of August 2013 an English version of MetaGer is available. MetaGer's source code was released on Gitlab at the 16th of August 2016.[11]

Filter bubble

A filter bubble – a term coined by Internet activist Eli Pariser – is a state of intellectual isolation that allegedly can result from personalized searches when a website algorithm selectively guesses what information a user would like to see based on information about the user, such as location, past click-behavior and search history. As a result, users become separated from information that disagrees with their viewpoints, effectively isolating them in their own cultural or ideological bubbles. The choices made by these algorithms are not transparent. Prime examples include Google Personalized Search results and Facebook's personalized news-stream. The bubble effect may have negative implications for civic discourse, according to Pariser, but contrasting views regard the effect as minimal and addressable. The results of the U.S. presidential election in 2016 have been associated with the influence of social media platforms such as Twitter and Facebook, and as a result have called into question the effects of the "filter bubble" phenomenon on user exposure to fake news and echo chambers, spurring new interest in the term, with many concerned that the phenomenon may harm democracy.

(Technology such as social media) “lets you go off with like-minded people, so you're not mixing and sharing and understanding other points of view ... It's super important. It's turned out to be more of a problem than I, or many others, would have expected.”

Fireball (search engine)

Fireball is a web search engine operated by Fireball Labs GmbH, based in Munich, Germany. Founded in 1996, Fireball was once the leading search engine in Germany, but quickly declined after being taken over by Lycos Europe and the rise of Google. In 2016, Fireball was re-established as an independent company and relaunched.

Internet privacy

Internet privacy involves the right or mandate of personal privacy concerning the storing, repurposing, provision to third parties, and displaying of information pertaining to oneself via the Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing.Privacy can entail either Personally Identifying Information (PII) or non-PII information such as a site visitor's behavior on a website. PII refers to any information that can be used to identify an individual. For example, age and physical address alone could identify who an individual is without explicitly disclosing their name, as these two factors are unique enough to identify a specific person typically. Other forms of PII may soon include GPS Tracking Data used by Apps, as the daily commute and routine information can be enough to identify an individual.

Some experts such as Steve Rambam, a private investigator specializing in Internet privacy cases, believe that privacy no longer exists; saying, "Privacy is dead – get over it". In fact, it has been suggested that the "appeal of online services is to broadcast personal information on purpose." On the other hand, in his essay The Value of Privacy, security expert Bruce Schneier says, "Privacy protects us from abuses by those in power, even if we're doing nothing wrong at the time of surveillance."
