The Fringe-P3 method
in forensic and clinical applications
The Fringe-P3
technique is a method to present a very large number of stimuli to the brain
and determine which of these the brain is familiar with by monitoring the
electrical response from the brain. The method was first presented as a
concealed knowledge test for which it is very difficult to apply
counter-measures, making it a potential deception detection technique. The
following papers verified the basic effectiveness of the method.

We are developing
the method in forensics with the company Visionmetric through
the following innovate UK project,
Forensic Facial Identification using the Fringe P3
brain wave response.
The work carried out
in this project is most fully illustrated in the following demonstration of the
EEGFIT system.
