A digital footprint refers to the tracks left by a person or entity using computers, phones, and online services which includes emails, text messages, file transfers, computer logs, tweets, voice and video calling, movements via cell phone location history, footage from traffic and security cameras, live chat, social media use, web searches, website visits, online and offline credit card purchases, financial transactions, medical data, criminal and civil court records, and business records kept by your service providers. In the wrong hands a person’s digital footprint can be used to obliterate a person’s anonymity, privacy, and liberty.
