What happens to the pictures published online? We can’t retrace who sees and uses our personal pictures. Our face, once it’s online, doesn't belong to us anymore.
Based on selfies, a contemporary version of portrait pictures, the custom database taking #selfie pictures of Instagram could have been created. The users whose portraits have been taken don’t know their pictures have been collected. Just as in picture databases made to develop computer vision systems, personal pictures are depersonalised and only useful for a technical purpose.
