So many of our daily activities leave multiple digital footprints, little records of our work and whereabouts. At a time when privacy is taken less seriously and more and more people make copies of what we do and say — whether friends or in some official capacity — digital footprints multiply quickly.
Phones, utilities, credit card purchases, cars, movie downloads, online purchases, and all of our social networking activities leave little bits of code — each recording some aspect of our activities. Many of these digital footprints are fairly obvious parts of daily life, easily accessible to us. Others, however, come from our association with people and web locations — site registrations, tagged digital photos, and comments we leave here and there. Sometimes we don’t even think much about signing up for a site — we just log in and then rarely use it again. We create a slew of less obvious digital and supposedly confidential footprints via our medical and bank records,and social security — in theory more private.
