In many movies, you have seen that after killing someone, the villain thumbs up his property and other necessary documents. But in reality it is far from the truth. This is not possible according to science.
Do you know that our fingerprints are not the same after death? It varies. Because after you die, the human body loses its electric charge. And it is this electric charge that keeps the body system of the body functioning.
So do fingerprints change after death? How long after his death is it possible to identify his print?
Your fingerprints are equally clear and understandable before death. Not so much after death. This not only changes but also becomes largely ambiguous. Its edge becomes sharp.
If you enjoy watching crime novels or those movies, you can’t think so. A study published on 14 July 2015 by the National Academy of Sciences found that increasing the time interval between two sets of printing makes fingerprint verification less reliable.
Usually, one’s fingers get stuck after death. This is why it is not easy to get his fingerprints. Special tools have been made for scientists. In such cases, fingerprints can be taken using these devices.
But often it becomes almost impossible to take fingerprints. Even if the dead body is very molten, fingerprints cannot be taken. But it is clear that there are many differences in the fingerprints of dead and living persons. Although doctors, forensic experts have only found out about them. So this is evident in laboratories.
Forensics people may soon find out that this print is of the living person or the dead. They are also easily detected in the laboratory.
Sometimes these fingerprints are also useful
However, it is not the case that fingerprints of dead persons are of no use. But there is a special type of symmetry in fingerprints after the living person and after death. Often the deceased is also identified by fingerprint. In this case, scientists use silicon putty to take prints. It can be used by taking photos of the print to print on a silicon strip.
Can a mobile lock be opened with fingerprints after death?
Nowadays every mobile phone has a fingerprint sensor. You will be surprised to know that this fingerprint sensor does not work after death.
Indeed, the technology we use with fingerprint sensors is so advanced that it quickly catches the gap between a dead person and a living person. If you touch a dead person’s finger on their phone’s sensor, it will not unlock.
What is the reason
The biggest reason behind this is that after death our fingerprints start shrinking. This is why this fingerprint technology understands the difference between a dead and a living person. Most fingerprint sensors can function within minutes of death but do not work again.
