All this week on BBC's Breakfast news, they are reporting on how an internet user can be tracked when on-line, by leaving their calling card otherwise known as cookies. These are created by leaving a line of code on your hard-disc which can then be identified by companies already being able to research your movements.

From this they can identify your shopping habits and how you in fact use the internet. This is raising concerns about how people's privacy rights are being affected and security companies are looking at providing policies to protect everyone's right to privacy when on the internet.

The articles are broadcast at around 7:15 am on BBC1 if you are lucky enough to be still at home by this time in the morning, it is well worth watching.
