Fingerprint Facts: Just as everyone’s DNA is different, similarly everyone’s fingerprints are also different. These fingerprints are very helpful for the identification of the person. Fingerprints are used for many important documents including Aadhaar and passport. Fingerprints are a very important thing in terms of our identity and security. But do you know that after the death of a person, his fingerprints change?
Actually, after death the electrical conductance present in the body also ends and our cells also stop working. After the death of a person, his fingerprints are not as reliable as before. After death the body gets stuck. In such a situation, our fingers also get stuck like other organs. It takes a lot of effort to get fingerprints after death. After death, there are changes in the fingerprint of a person. It can be detected only by forensic expert or in the lab.
Only experts can take accurate fingerprints
Forensic experts do not have much difficulty in identifying the fingerprints of a living and a dead person. These people easily identify them. In forensic labs, silicon putty is used to take fingerprints of a dead person. Fingerprints come clearly on silicone putty, which can be detected by taking a picture.
Phone cannot be unlocked after death
After death, a person’s mobile cannot be unlocked with his fingerprints. Actually, the sensors of mobile phones work on the basis of electric conductance running in human fingers. Since, the electric conduction present in the body of death ends. That’s why mobile phone sensors cannot detect fingers without electrical conduction.
