Mindprint

[petrushkagoogol]

If you show a subject a series of pictures, for example - 

* a car 
* a tree 
* a rose 
* a gun 
* photo of self 

and measure the EEG trace in each case, and then blend the same using some suitable algorithm to generate a composite waveform, can we generate a unique "mindprint" for each individual ?

Yes.

 

This has actually been done by a team lead by BYU’s Sarah Laszlo and Zhanpeng Jin, with 97% accuracy in 2015, and, for a test group of 50 this year, 100% accuracy. They call the identifying data produced by their method a “brainprint”, not a “mindprint”, though I think the latter term is really more accurate, since the technique isn’t measuring anatomical features of the brain, but brain activity caused by an individual’s fairly unique perceptual brain functions. They might have done it because “mindprint” is already used for some commercial products, such as professional training services.

 

We discussed this a little in the 20 Apr 2016 Fulldive technology forum thread “Brainprints?”
