This is a fascinating post on a project using one users search history over a three-month period and how that search history can not only identify you (e.g. via ego searches, searches of others close to you, etc.), but can also reveal your story. If you have an interest in privacy, security, and big data read this. Even if you think you have ‘nothing to hide’ you should think about the things you might keep private for whatever reason and how those might be used by businesses or others for good (e.g. ‘you might be interested in…’ based on your purchases/browsing/watching history) or evil.
