b. Brain test
c. Brain print
d. None of the above
ANSWER: Brain print
Scientists have developed a new system that can identify people using their brain waves or ‘brain print' with 100% accuracy, an advance that may be useful in high-security applications.
- The researchers at Binghamton University recorded brain activity of people wearing the EEG handset when they looked at images and unique brain response was elicited
- Participants' brains reacted differently to each image, enough that a computer system was able to identify each volunteer's 'brainprint' with 100% accuracy.
- According to Laszlo, brain biometrics are appealing because they are cancellable and cannot be stolen by malicious means the way a finger or retina can.
