Case Study DuckDuckGo is a search engine that promises users that it will not collect any personal information from them in order to display ads based on tracking their previous searches and locations on the Internet. DuckDuckGo says that it is different than Google because Google puts millions of tracking devices on websites, allowing the company to see and remember every search a person has made and every website they've visited from those searches. According to the DuckDuckGo website, Google uses the massive amounts of information they collect on individual users to deliver targeted advertising, and to monitor which advertising gets viewed and clicked on. Since its inception, use of DuckDuckGo has risen steadily as users become more and more concerned with privacy. Because DuckDuckGo does not track user information, everyone who enters the same search term gets the same search results. DuckDuckGo makes money in the same way Google does, by selling advertising, but their advertising is based only on search results not on compiled personal data. For example, if you search for "craft beer" you will get ads from other craft beer sites, but DuckDuckGo does not remember your previous search for "San Mateo, CA", so it will not give you only craft beer locations in San Mateo. DuckDuckGo was founded in 2008, while Google was founded in 1998. This means that Google was more likely to have a than DuckDuckGo. Suppose you have just started a small business, and you have limited advertising dollars. You can't advertise on both Google and DuckDuckGo, so y must choose one over the other. You realize that Google can give you more targeted advertising because they have more information about consum than DuckDuckGo does. This is an issue with: O Information relevance Information completeness Information accuracy O Information timeliness Suppose that the developers of DuckDuckGo became concerned that Google engineers were trying to hack their system so that Google could get access to the search requests made on DuckDuckGo. Which of the following steps could they encourage users to take to prevent the hacking from working? Check all that apply. Use a decision support system Use electronic data interchange Use a system of public/private key encryption Work on a virtual private network (VPN)
