Your Thoughts Are Your Password

Could you imagine yourself living in a world where text passwords are a thing of the past and all you'd need to do to log in your computer is to think about it? Scientists hope that mind-reading computers will one day replace typed passwords, making fingerprint readers and retina scans obsolete. Thoughts are unique to individuals, so using them as passwords would probably be incredibly secure. You would need to reproduce a person's thought pattern exactly in order to get in a protected system, and my guess is that this would be an almost impossible task.

What if you could one day unlock your door or access your bank account by simply "thinking" your password? Too far out? Perhaps not.

Researchers at Carleton University in Ottawa, Canada, are exploring the possibility of a biometric security device that will use a person's thoughts to authenticate her or his identity.

  • It's a very interesting thought, and with the removal of textual passphrases from common usage, this kind of technology would likely eliminate brute-force attacks on a large scale.

    Unfortunately, having a system of authentication that uses credentials that are theoretically impossible to reproduce doesn't elminate a man-in-the-middle attack. It all depends on how the scanning/recording technology works, but as Schneier recently wrote (with regard to RFID tags) the attacker doesn't necessarily have know or replicate the token...they just have to be in a position to capture and rebroadcast it. This attack would likely not be much of a practical issue in this case, but it's still a potential hole.

    But hey, it'd probably still be loads more secure than what we've got going on these days anyway.

  • In my case, a "women-in-the-middle" attack! Fear me!

    Keep it going guys, I love this blog :)
