A team of researchers says that in the near future we will be able to use our heartbeats as passwords.
We have been looking for a substitute for passwords for a long time; a simple but highly secure method that allows us to save our data from unwanted looks.
The biometric, using our own body as a password, has not finished taking off as alternatives; however, the latest study from Binghamton University in New York indicates that we could use it more intelligently.
Looking for the perfect alternative to passwords
The team of researchers has concluded that we can use the heartbeat as passwords; specifically, they could serve to encrypt our personal medical data. And all this, without having to do anything special.
Today there are many methods for storing and encrypting private data; but they all require complex arithmetic calculations and the generation of random numbers. Not ideal for wearable systems, where battery consumption and reduced processing capacity prevail.
That is why the idea that researchers have had is so interesting; instead of generating an encryption key, they can use the one generated by our own hearts. The idea is to use the same methodology to capture the electrocardiographic signals that are used for diagnosis.
How could we use heartbeats as passwords
The system will reuse the same data obtained to generate a unique key; This password will be used to access our medical records. In this way, we would have complete security that no one can access this private data; Privacy between doctor and patient would also be enhanced.
At the same time, the systems of the future are unlikely to use this method exclusively; and is that our heartbeats are somewhat inconsistent, depending on whether we are calm or tired, or even our mental state.
So the proposal is that this system be a secondary authentication system; This would complement other systems to add a layer of security but without depending on it.
