Brain fingerprinting is a new scientific technology introduced by Dr. Lawrence Farwell. Brain Fingerprinting uses electroencephalography (EEG) to determine whether in the person's brain the specific information is present or not. This technology involves working on P300 MERMER (Memory and Encoding Related Multifaceted Electroencephalographic Response). Using this technology a subject’s brain response and their electrical brainwave are recorded and measured. When the human brain recognizes important information it triggers a special electrical signal called MERMER.

A terrorist or other dangerous person can be identified by measuring person’s “brain print” whether they are familiar with a given phrase, sound, or photo. Specific pattern is revealed in EEG when brain process event related information. Brain fingerprinting does not require verbal response to question or stimuli from the subject. Brain fingerprinting doesn’t detect lie, anxiety, or feeling. Brain fingerprinting computes whether information is present or not.
