Can They Unlock Our Phone With Our Fingerprint When We Die?

Our answer to this question is both technological and biological It will be with its dimensions.

your secret photos, If you haven’t deleted your messages, we have some news for you.

What is the logic of fingerprint technology?

Fingerprint scanners have become an indispensable part of the security systems of today’s smartphones. fingerprint scanners, It analyzes the unique patterns on our fingertips and creates biometric data specific to each individual. When we turn on our phones, this pattern is scanned and if it matches the previously stored data, the device turns on.

However, this technology does not only depend on the fingerprint pattern. Scanners are also located on the surface of the skin. electrical activity It also perceives.

The most critical point here is that the fingerprint is not only a physical pattern but also a sign of vitality It is also perceived as. So our phone needs to detect us as “alive”.

Will our fingerprints work when we die?

Unfortunately (or perhaps fortunately), when we die, some biological changes occur in our bodies. The structure of the skin on our fingertips and Moisture balance deteriorates over time and with the loss of vitality, electrical activity ceases.

This means that biometric security systems realize that our body is no longer “alive”. After a few hours, our skin begins to deteriorate and fingerprint technology no longer works. He becomes unable to recognize us.

Many fingerprint scanners check this electrical activity at the fingertip, detecting not only patterns but also whether the finger is alive or not. This is when we die electrical activity disappears and our phone cannot recognize our fingerprint for this reason.

Use of fingerprints in forensic medicine

Of course, fingerprints play an important role even after death. In forensic medicine, in identification It is still one of the most reliable methods.

It is possible to take fingerprints immediately after death because biological structures do not deteriorate immediately. But the important thing here is that phones biometric scanners The fact that it works with a different logic.

Forensic experts While fingerprints remain an important means of authentication, our phones may not accept them. So we ripped it!

Alternatives for phone security

With developing technology facial recognition and iris scanner Biometric security methods such as have also become popular. Some of these systems, especially facial recognition systems, can be unlocked with a dead person’s face.

However, many advanced systems liveness detection It can tell whether a person is alive or not by using a feature called.

As a result, the world of technology is also intertwined with biological realities. So even when we die privacy and security remains important. So, rest assured! After you die, no one will be able to access your phone with your fingerprint.
