There are many stories of someone altering or removing their fingerprints, most of which are purely fictional. While you could, potentially, remove your prints, the process would be long and painful, and eventually the skin would grow back and have prints on it once more. Scarring your fingertips would change your prints, but the prints are still there, just altered. While you can change your prints, it’s not as easy as popular media would lead you to believe.
Facial recognition does not work after plastic surgery is carried out
Only if you are having your face completely reconstructed including changing your underlying bone structure, would your facial recognition solution be fooled.
A significant portion of plastic surgery operations consist of ‘minor’ changes such as rhinoplasty or procedures to reverse the signs of ageing.
They don’t alter the key characteristics that facial recognition algorithms use to identify you – the relative position of your eyes, nose and mouth, the shape of your eyes, your jawline, etc.
