DuckDuckGo differs from other search engines by not profiling its users and showing all users the same search results for this search term. The company is based in Paoli, Pennsylvania, in Greater Philadelphia and has 111 employees since October 2020. The name of the company is a reference to the children's game duck, duck, goose. The results of the DuckDuckGo Survey are a compilation of more than 400 sources, including Yahoo! Search BOSS, Wolfram Alpha, Bing, Yandex, own web scanner (DuckDuckBot) and others.

The Autonomous Surfer
Renée Ridgway The Autonomous Surfer CAIS Report Fellowship Mai bis Oktober 2018 GEFÖRDERT DURCH RIDGWAY The Autonomous Surfer Research Questions The Autonomous Surfer endeavoured to discover the unknown unknowns of alternative search through the following research questions: What are the alternatives to Google search? What are their hidden revenue models, even if they do not collect user data? How do they deliver divergent (and qualitative) results or knowledge? What are the criteria that determine ranking and relevance? How do p2p search engines such as YaCy work? Does it deliver alternative results compared to other search engines? Is there still a movement for a larger, public index? Can there be serendipitous search, which is the ability to come across books, articles, images, information, objects, and so forth, by chance? Aims and Projected Results My PhD research investigates Google search – its early development, its technological innovation, its business model of the past 20 years and how it works now. Furthermore, I have experimented with Tor (The Onion Router) in order to find out if I could be anonymous online, and if so, would I receive diver- gent results from Google with the same keywords. For my fellowship at CAIS I decided to first research search engines that were incorporated into the Tor browser as default (Startpage, Disconnect) or are the default browser now (DuckDuckGo). I then researched search engines in my original CAIS proposal that I had come across in my PhD but hadn’t had the time to research; some are from the Society of the Query Reader (2014) and others I found en route or on colleagues’ suggestions. -

Conclusion 26 2 Dark Web Investigation Guide 1 1. Introduction 3 Introduction 1 There is a lot of confusion about what the dark web is vs. the deep web. The dark web is part of the Internet that is not accessible through traditional means. It requires that you use a technology like Tor (The Onion Router) or I2P (Invisible Internet Project) in order to access websites, email or other services. The deep web is slightly different. The deep web is made of all the webpages or entire websites that have not been crawled by a search engine. This could be because they are hidden behind paywalls or require a username and password to access. We are going to be setting up access to the dark web with a focus on the Tor network. We are going to accomplish this in two different ways. The first way is to use the Tor Browser to get Google Chrome connected to the the Tor network. This is the less private and secure option, but it is the easiest to set up and use and is sufficient for accessing material on the dark web. -

Not long ago it was speculated that the leading world economic and political powers were engaged in a cyber arms race; that the world is witnessing a cyber resource buildup of Cold War proportions. The implied threat in that assessment is close, but it misses the mark by at least half. The threat is much greater than you can imagine. We have passed the escalation phase and have engaged directly into full confrontation in the cyberwar.
