I was one of those happy participants of TSC 2010 that took place in Tucson, Arizona past week. It is the biggest event dedicated to consciousness this year, with diverse participants and their approaches ranging from meditation and philosophy to neurobiology and quantum physics.

The last few months were too overwhelmed with events, projects and laziness… But now I’m back to blogging 🙂

Regarding KT88-1016, I think I’ll have to abandon this project for an undefined time! Got a BCI-related job here, and anyway, everyone is going for Emotiv now. And I became disappointed now in capabilities of EEG-based BCIs – invasive approach definitely offers more!

“Brain-wave signatures, represented as the EEG signals of a person … are different from one individual to another, even when they perform the same thought or task”, “A brain-based biometric can be as strong as DNA-based biometric”

Touradj Ebrahimi

Brain of each human being is completely unique. Its structure is highly influenced not only by our DNA but also by everything we experience in our life. You can find people even with the same DNA – but life history is something that cannot be duplicated.

So brain activity is unique biometric every person has. And such biometrics are used in access control systems when security is needed. Simply, you can use your biometric as a password to gain access to resources protected from everyone except you. And brain activity has a lot of advantages over other biometrics traditionally used in access control systems (such as fingerprints). Here are the most important ones:

  • Brain activity is secure. In case of fingerprints, for example, we leave biometric in every place we touch with our hands, so everyone who needs to attack the system can collect & replicate it. Brain, in contrary, is safely hidden inside a skull.
  • Brain activity is changeable. You cannot influence other biometrics – your iris pattern, DNA, heart beats, fingerprints – are determined by nature and there is no easy way to modify them. If system based on these biometrics is compromised once, it is compromised forever. Brain activity, conversely, can be easily changed just by simple thought.
