Shops could soon be targeting ads according to your feet

There are eyes on you, behind the bright lights and mirrored panels. Pick up a boot and a camera will make sure you don't slip it into your bag. Cross the threshold into a department store and there is a tacit understanding that you will be watched, but new technology is leading retailers to grow a different set of peepers – eyes less focused on shoplifting and more interested in your age, sex, size, head, shoulders, knees and toes. A few months ago, IT firm Computer Sciences Corporation (CSC) put out a report that claimed around 30% of retailers use facial recognition technology to track customers in-store. It is technology that can identify people by analysing and comparing facial features from a database.
