DuckDuckGo - a hybrid search engine with an open initial code. Has been working since 2008. Having gone to the page at once it is possible to notice that this search engine places emphasis on anonymity, about what it is possible to read the whole article (http://donttrack.us/), having pressed the word "anonymously". The problem of anonymity rose after it became clear that Google, Microsoft and others sent data of users to Agency of National security of the USA.
DuckDuckGo doesn't sin with abundance of advertizing, search spam, supports hotkeys. Pressing the word it is "instantly" possible to choose area in which it is necessary to carry out search that does search results more exact.
DuckDuckGo doesn't use a bubble of filters as it is done by other searchers (Google, Bing, Yandex). It means that all volume of information, and not just what as the search engine counted, will be interesting to the specific user is provided to the user.
DuckDuckGo by default uses work between the client with the server under the HTTPS protocol with use of algorithm of enciphering of RC4 and a key 128 bits long (it everything is very good). As supports the OpenSearch technology, and it is easily added in the list of search engines of the browser.
DuckDuckGo works in cooperation with Yandex which uses system of a bubble of filters. And this fact sets thinking: and whether really DuckDuckGo watches us? Different people expert in this case say that DuckDuckGo is absolutely honest with the users (by the way, in 2011 on a site DuckDuckGo.com in day was only 200.000 person, and in 2013 a search engine processed 3 million inquiries a day!) . To trust promises on a site or not - your business.
According to the site alexa.com the site takes the 730th place in the world on attendance, and it is especially popular in the USA (43% of users live exactly there). The site gains the popularity, and increases number of the countries which inhabitants prefer anonymity in a network.
DuckDuckGo, Mozilla, Reddit, 4Chan, Internet Archive, Greenpeace and the American union of protection of civil liberties (ACLU) made and signed the open letter in Obama's administration with an appeal to check powers which the American intelligence services in particular mass shadowing the civilian population possess. This letter can sign everyone, having passed to a site stopwatching.us
I don't know about you, but I will pass from Google to ducks.
