Mtodo de deteccin de mentiras basado en sistema grafomtrico

Una empresa hngara ha desarrollado un mtodo de deteccin de mentiras para evaluar la

credibilidad de las declaraciones hechas por una persona sometida a una investigacin. Laspreguntas orales se responden de forma escrita para que la persona evaluada no se ponganerviosa. Esta tecnologa est indicada para autoridades judiciales y cuerpos de polica, aunquetambin puede aplicarse en empresas privadas. La empresa busca socios interesados enadaptar la tecnologa a sus necesidades locales.

Abstract---------------------------A small Hungarian business venture has developed an alternative lie detection method. It is usedto assess the credibility of statements made by the person under investigation. Benefits: oralquestions are answered in writing, so the person assessed does not become nervous. Thistechnology can be used by judicial authorities and police forces but also applied in the service ofprivate companies. The company looks for a service partner to adapt the technology to foreignlocal specifications.

Description---------------------------The company is mainly involved in judicial expertise, but also provides training related to liedetection, personality assessment and graphology.The proposed handwriting-based, alternativelie-detection-method (graphometrics) provides an extensive analysis of physiological changes inthe person under investigation (called 'duktor'). It assesses, with highprecision and high definition, what emotional, mental and senso-motoric responses are induced,in a person's psyche, by a specific sentence. These responses, when compared withother details of the criminal investigation, lay the foundations for determining the direct truthcontent. During the procedure, the so-called 'triple probe' principle isapplied.The 'triple probe' method requires two distinct homogeneous

groups of writing samples: One must contain demonstrably true facts, whilst the other mustcontain demonstrably false facts. By comparing the same characters in two samples, it is possibleto determine the graphological features of false confessions. The third element to be assessed the (incriminated) writing which serves as the basis of accusation is subjected to the sameanalysis method, and then the level of conformity to the 'false - true'sample is examined. In this way, a conclusion can be drawn, based upon a specific probabilitylevel the degree of probability of whether the responses expressed in the handwriting of theperson assessed are true or false. The 'triple probe' procedure can also beapplied in those special cases where it is believed that the incriminated written material has beencreated under pressure or threat.This procedure may be used as a substitute for the polygraphicexamination method, since it does not require any polygraphic equipment which, beingconsidered to be military technology according to some national laws may be difficult to obtain. If

necessary, the procedure can also be applied in combination with the polygraphic procedure.Theproposed method requires the use of a special writing interface (writing tablet, with paper) whichis connected to a notebook computer, and, also, the proprietary software. Concerning the personbeing tested, the following are assessed:- how much the pen is pressed against the paper,- whenthe pen is lifted,- how quickly the pen is moved, etc.The equipment analyses the data collectedduring the test using mathematical methods (algorithms), so the conclusion drawn is based onobjective factors.In order to apply the proposed method, the consent of the person underinvestigation is required.Innovative Aspects:New features of the proposed technology: - Liedetection is carried out based on writing.- This procedure combines the benefits of methodsalready in use. From the method of polygraphic lie detection, it has borrowed the principle ofassessing changes in contrast with responses to neutral questions. It has also taken the methodof assessing changes in lettering from graphology. - During polygraphic lie detection, onlyphysiological changes (blood-pressure, pulse, respiratory-rate etc.) are assessed.In contrast withthis, the proposed technology records reactions corresponding to the content in the psyche of theperson under investigation, without influencing the persons behaviour through the use of differentsensors.Benefits of the proposed technology:- Objective. Since ones pulse can be influenced byyoga, or by autogenic training, the polygraph may well be deceived. In graphic expression,however, a change in writing accompanying psychical changes is the result of a higher levelmental activity, and therefore writing cannot be influenced.- Time-saving.- Cost-efficient (no needto buy a polygraph).- Widely available, since it is not considered being military technology unlikepolygraphs.- The digitalisation of the writing, and the computer-based evaluation, can be carriedout either by writing on the interface (online assessment) or by scanning (offline assessment).- Itcan be used to assess any Latin-alphabet handwriting. It is also capable of handling accents,periods, overscores and underscores, etc.
