Many criminals have various tattoos and they keep one step ahead of the law by changing their tattoos, particularly if they have them at very visible places which can be used for identification purposes. Sometimes tattoos are reworked, sometimes they are ‘removed’ in a bid to make identification difficult.
But now scientists and researchers at the University of Derby have figured out ways of using digital cameras with infra-red sensitivity which will enable them to know whether the tattoo is original or has been reworked or erased.
David Bryson, senior lecturer applied photography and forensic science at the university said, ‘Identifying individuals using tattoos has been an established part of forensic science practice for some time, but there can be cover-ups of tattoos with lasers, more tattoos or surgery.’
Using this kind of camera hidden layers of the skin can be seen and it can be determined whether the tattoo is original or not. It can also prove helpful in identifying corpses without any other identification at the morgue – and tattoos can be of great use in identifying individuals.
