Your Heartbeat Could Replace Computer Password

Soon your heartbeat could replace your computer passwords

The uniqueness our your heartbeat could provide the encryption needed to unlock your various devices. A scientific team has successfully translated a human heartbeat into an encryption key. Each person has a unique heartbeat and it also never repeats its pattern so you would never get the same encryption key twice.

The goal is to integrate the system into hardware so that users can both encrypt and decrypt their devices with the touch of their hand.

The research was conducted by Chun-Liang Lin at the National Chung Hsing University in Taichung, Taiwan.

  1. This post is extremely thought provoking. My first response is if it can work, that would be revolutionary past the point of any authentication we have to date. Heartbeats are specific to the person. However it’s true they are frequently changing so my question would be how would the system authenticating the heartbeat keep up with what to look for? However, if it did work, it would be nearly impossible to duplicate someone’s heartbeat therefore dealing a serious blow to potential attackers.

  2. I think this is one of those stories I am going to have to keep an eye now that I know about it. To think that someone has been able to translate a heart bet into an encryption key is mind blowing. I am going to have to do some more research on this topic. Something like this has the potential to change network security as we know it now. I wonder what the cost for this technology will be?

  3. I found this post very interesting and did a little researching myself to see if what how far in the future this technology could be. I determined that although this bio-metric type of cryptography is in very early stages of development, it could perhaps be the answer to one of the most pervasive issues concerning current bio-metrics. There already exist technologies for iris scanners, fingerprint scanners, or voice-recognizing products but many of these new ideas suffer from poor implementation and are somewhat insecure. This type of “heartbeat cryptography” could solve all of those previous issues. Ill be sure to keep an eye on this research as it could be a new alternative to passwords.

  4. After reading the attached articles, I see this as being an interesting development of biometric security. However, I believe that it will be quite a few years until this technology will actually be implemented, if at all, since I can tell that there has to be a long way to go before the method is refined enough to work consistently.

    According to the original article, the technology bases itself on “an irregular pattern that never repeats” and that “you won’t get the same key twice” from it. The math that has to go into this must be weird, since I don’t really know how you could get a consistent positive reading from something that often changes.

    Regardless, I do have some faith. If they can find a way to make this work in a way that is nearly error-free, this research might turn out to provide yet another effective means of securing information without having to remember long passwords. I hope to hear more progress and testing of this technology in the future.

  5. This would be an amazing step forward in bio security. To this day we haven’t found a completely safe way of using the human body to secure or lock down information. Fingerprints can easily be captured from something a person touched and retina scanners should be deprecated on the basis of how easy it is to duplicate. Being able to develop an algorithm that uses a human heart beat as an encryption key would be a remarkable / revolutionary step forward in security. This way a person literally cannot hack into someone’s computer with the actual person present. My question though is how this would be implemented considered a heart beat doesn’t have much consistency and changes based on whether someone is ill or even just went for a morning run before work..

  6. This was honestly one of the most interesting things I have ever read. Although it seems ridiculous and near impossible now, so did the concept of fingerprinting and eye scanning analysis 20 years ago. This type of technology would leave very little room for error and security breaches. However, while they discuss the uniqueness of every individual’s heartbeat and their constant changes, how can one match someone’s heartbeat one day to their heartbeat another day?
