Forensic Brainwave Analysis

Forensic Brainwave Analysis currently has three areas: Brain Fingerprinting (BFP), Complex Trial Protocol and Brain Electrical Oscillation Signature Profiling.

BFP is an ERP*-based knowledge detection technology aiming to detect whether or not a person possesses information about a crime-scenario in their brain. BFP can also detect presence or absence of episodic memory information in non-criminal scenarios; and to detect if a certain person is a member of a group with some specific knowledge.
BFP was invented in the early 1990s by Dr Lawrence (Larry) Farwell - who is currently the Chief Science Officer of the Brain Fingerprinting Technologies.

I worked with academics from psychology and law in a New Zealand Law Foundation project to replicate the accuracy and reliability of the BFP technology with general population and with parolees.

An EEG headset (see the figure) and a computer software are used in this technology.
Can we beat Brain Fingerprinting?
I am currently investigating a cognitive psychology technique known as Think/No-Think in collaboration with the University of Cambridge, UK (read further). Think/No-Think might be used as a countermeasure against BFP. We are currently at the initial stages of the project. There is a potential for prospective Honours, Master’s and PhD students to work with us on BFP and Think/No-Think at the University of Canterbury. This will tell us what type of people could employ Think/No-Think, and potentially beat BFP.
