Now my Android smartphone has figured out where I live, where I work and where my friends live. Depending on the time of day and my location, it will give me an ETA to where I'm likely to travel. A simple search for a new drinking hole on my laptop will tell my phone to have travel instructions at the ready.
In practice this means I will never be lost again. It also means Google knows a lot about where I am, where I go and when. But Google isn't alone in collecting user information. In fact many sites send user information out to other sites without the user ever really noticing it. I hadn't realised the extent of online tracking until I saw my Collusion map -- a browser add-on developed by Mozilla. Collusion creates a real-time map of the websites you are visiting and the websites with which they share your information. Here's what mine looks like while writing this: (All the grey bubbles are sites tracking my online activity)
[[{"type":"media","view_mode":"media_large","fid":"438","attributes":{"alt":"","class":"media-image","height":"353","width":"480"}}]]
[[{"fid":"19430","view_mode":"default","fields":{"format":"default","field_file_image_alt_text[und][0][value]":"Collusion for Chrome","field_file_image_title_text[und][0][value]":"Collusion for Chrome"},"type":"media","attributes":{}}]]
A recent survey carried out by the EIU on behalf of Beazley, a specialist insurer, found that consumers have become more liberal in sharing their data compared to three years ago, but they're also very concerned about how the data is being used and by whom. Add-ons like Collusion help users understand with whom their data is shared, but it does raise the question of whether websites track more user information than they actually need.
"The problem is that people have not had an alternative to which they can switch to without a cost. There's been no choice", says Gabriel Weinberg, founder of DuckDuckGo, a search engine. "What we have been trying to do is create an alternative – and better – search engine." Mr Weinberg believes that as more and more people realise the extent to which their privacy is being violated, more and more will use certain services less.
DuckDuckGo, unlike its principal rival in the world of search engines, doesn't track user information. It's a way of searching the web that is entirely anonymous. Mr Weinberg found it odd that search engines know so much about their users, which isn't required for monetisation. He was also uncomfortable with how governments can require sites such as Google to share their data.
"The threat to personal privacy has become worse", says Mr Weinberg. "If companies can use information to increase profits, they're going to do it eventually. It's just a matter of getting the right information to the right people". Part of the reason why the threat has become more real is the significant improvements in the data analysis tools. "Five years ago companies just did not have the infrastructure to collect, aggregate and sell personal information. But now it's starting to be there. The problem is real, it's just people don't know much about it."
So how can Internet users protect themselves online? One solution, according to Mr Weinberg, is to use add-ons and apps that block trackers. Ideally, though, sites like Google would stop tracking by default as DuckDuckGo does, rather than asking users to 'opt-in'. And proper anonymity of search data would be welcome. This would include deleting IP addresses and disaggregating search sessions.
There are of course benefits to having a global data bank as vast as Google searches. It can help us track and respond to flu epidemics, discover unexpected side effects of prescription drugs, and prevent us from ever getting lost again. One question remains difficult to answer, however: is giving up privacy a fair price to pay?
