This invention relates to the detection and signal processing of electrical brain activity.
The purposes of this invention include the detection of information processing undertaken in the brain, the detection of concealed information in the brain, communication from the brain to a computer, and command and control of computers and electronic and mechanical equipment by the brain.
The Farwell MERA System is a new technology for the detection of concealed information that revolves around the non-invasive recording of brain electrical activity. The electrical brain activity pattern recorded and of interest is a specific multifaceted electroencephalographic response (MER) that occurs immediately after an examinee is visually presented (via a computer screen) with words, short phrases, acronyms, or pictures that are recognized and cognitively processed by that subject. This phenomenon, coupled with its absence following the presentation of the same information to a subject for whom the material is unknown or irrelevant, is the basis for discriminating between subject guilt and innocence. This would potentially allow for the determination of a whole host of issues of interest to the law enforcement and intelligence communities, e.g., (1) does a suspect have guilty knowledge connecting him to specific investigated criminal activity, (2) does an intelligence source have knowledge of the internal workings of a hostile intelligence agency that would indicate that he was an intelligence officer of that agency and not who he claimed to be, (3) has an informant, a debriefed spy, or a suspected member of a criminal organization accurately described the entirety of his actions and knowledge, (4) did a convicted serial killer who claims to have killed 40 to 50 individuals, other than the one(s) he was convicted of, actually commit these acts, or are these claims merely the bravado of a condemned prisoner.
The potential benefit of this program extends to a broad range of law enforcement applications, including organized crime, violent crime, white-collar crime, drug-related crime, foreign counterintelligence, non-traditional targets, and other categories of casework as well. This new technology promises to be of tremendous benefit both at the national level and for state and local law enforcement agencies.
This application describes a technology that is capable of detecting concealed information stored in the brain through the electrophysiological manifestations of information-processing brain activity. Additional information is described in a previous patent application of the inventor, U.S. patent application Ser. No. 08/016,215, entitled "Method and Apparatus for Truth Detection" filed on Feb. 11, 1993, which is expressly incorporated herein by reference.
This technique provides a means of distinguishing guilty and innocent individuals in a wide variety of law enforcement and information detection situations. The research described below demonstrates that the system is also effective in distinguishing between members of a particular organization (in this case, the FBI) and others who are not knowledgeable regarding that organization.
When a crime is committed, traces of the event are left at the scene of the crime and elsewhere. The task of the investigators is to reconstruct what has happened and who has been involved, based on the collection of such evidence.
In addition to the physical and circumstantial evidence that can be obtained, there is one place where an extensive record of the crime is stored: in the brain of the perpetrator. If this record could be tapped, criminal investigation and counterintelligence could be revolutionized.
Until recently, the only method of attempting to discern what information regarding a crime or other situation of interest was stored in the brain of a suspect or witness has been (1) to interrogate the subject, and (2) to attempt to determine whether or not the subject is lying.
Conventional control question (CQT) polygraphy has been used as an aid in the attempt to detect deception in such reports. The fundamental theory of conventional polygraphy is that a deceptive individual will be more concerned with and experience more emotional arousal in response to relevant questions than control questions, and this emotional arousal will be accompanied by corresponding physiological arousal which can be measured. Traditional interrogative polygraph ("lie detection") methods rely upon using questioning formats in conjunction with the recording of physiological parameters that reflect autonomic nervous system (ANS) activity (e.g. blood pressure, heart rate, sweating, etc.). This information is peripheral to the cognitive aspects of deception or of concealing guilty information.
