In the third video in a series of short, informative videos on privacy, Google explains what cookies do and how they can help web sites and advertisers personalize our online experiences. Cookies are small pieces of data that save information when you visit websites so you don’t have to re-enter it every time you return. For example, cookies help search engines remember that you want your search results in English and help online stores remember the items saved in your virtual shopping cart. Advertisers can also use cookies to deliver ads that are more relevant to you. You can always decide which cookies to accept – or whether to accept cookies at all – by going into your browser’s privacy settings.Duration : 0:5:1

Big controversy over personal privacy using code on your computer to track search requests, and enable a personal profile to be built up. This means that search results and advertising can be targeted to the individual person using a web browser. Search engine cookies from engines like Google had been set in the past to remain active for more than a decade. Under pressure from the EU, Google recently announced that the two years of user history they keep would be reduced to 18 months. Expect pressure to continue for personal opt out boxes enabling search engine users to block personal data from being stored. Expect search engines to push back perhaps by only allowing the fullest search results for those who give personal data to be stored. As it is they will claim (correctly) that personal history is vital to make the results as relevant as possible. Expect big civil rights debates and worries about invasion of personal life by security agencies.
