One of the murkiest areas of Internet commerce is the international trade of personal information gathered by certain companies who monitor our behaviour online. This kind of third-party data gathering is ubiquitous on the web thanks to the humble “cookie”.
A cookie is a small piece of data that a website loads onto your browser. Every time you visit that site in future, the browser sends that cookie back to the server so that the website can correlate this with your previous activity.
