What is a digital dossier?

It is the accumulation of all the digital tracks you leave behind.
Many people don't even realize that they have one, or what it is. It begins before you are born- sonograms may be forwarded through email or text message, pictures are taken of you as you grow up, and maybe shared online. Websites such as Google save all your search details, Facebook tracks your activity, and all of this is filed under your name. People can know what type of person you are, through pictures, your history, all you interests and hobbies you post about online, even the things you buy. Your personality is saved in a file consisting of all this information. Even your relationships with other people are known, through messages and pictures and adding someone as your sister or aunt of Facebook.
People aren't aware they are leaving this trail of crumbs behind them every time they send a text or use the internet. I think that teenager in particular are vulnerable here, as they may not be mature enough to think of consequences in later life. I didn't know what a digital dossier was until researching for this post. To me it is an important thing to know, especially when you're young and make mistakes that are recorded forever, without you even realizing. as you grow, your life will be recorded through photos, posts, and updates.
This was really interesting to me as i knew nothing about my digital dossier before this. watch the video here
