Online Activity Tracking

Many people have concerns about how their online activity is tracked. It is now easy to track activity such as:

Websites you have visited

Using cookies, it is possible to track your Internet history.
Advertisers sometimes use this to show you relevant adverts.
There is a lack of regulations about tracking data, which has led to some companies tracking data without permission.

Search terms you have used

Your search terms are tracked, and often used in marketing.

What you have purchased

Purchased items are often recorded and sold to advertisers who might wish to advertise similar products to you.

The Internet of Things

The Internet of Things is a fairly new but fast-growing concept where a network of physical devices and appliances can connect and exchange data.

The Internet of Things

The Internet of Things (IoT) relates to a concept where computer systems are integrated into every day objects, so that they can all exchange data.

- Your location and movement habits (using GPS).
- What you look like (using facial recognition).
There are some concerns about governments using the IoT to perform surveillance on citizens.
