Problems solved by technology

[0003] This expert group is very authoritative in the scientific community. Although their report believes that the traditional polygraph technology lacks scientific basis, and the measurement results are slightly higher than the random level, they do not approve of the US government supporting this technology; however, on November 5, 2002 John P.Stenbit, Assistant Secretary of the US Department of Defense submitted a memorandum to the Pentagon Office of the Senate, clearly stating that it will continue to support the application of this technology, because it is very important to the work of related departments, and the US Department of Energy also expressed the same attitude

Embodiment Construction

[0033] The event-related optical signal acquisition and analysis system and lie detection method involved in the present invention are realized in this way. according to figure 2 Provided a schematic diagram of the polygraph detection process, before implementing the test, according to the system requirements, the figure 1 The shown light guide cap 14, near-infrared laser 13, scattered light signal acquisition and control system 16 and other hardware equipment are completed, and then the computer and audio system are prepared, and the following work is carried out according to the lie detection process. The chief examiner first uses polygraph software to establish a database of people under test, a database of test materials, and a test template based on the materials of the case. In addition, the stimulus content such as text, voice or image required in the establishment process is collected by the investigators in advance with a digital camera or DV machine on the spot, an...

Abstract

The invention relates to a system for acquiring and analyzing event-related optical signals and a lie detecting method, and relates to recognition technology and a recognition method for honesty and cheat of a litigant in national security, public security, justice and civil dispute. The invention provides a lie detecting method using EROS by overcoming the defects of the prior lie detecting technology and products, absorbing the experiences of the prior lie detecting technology and the products, and also absorbing latest theory and technological achievement of the contemporary cognitive neuroscience and photoelectric technology. The system consists of a photoconductive cap, a near infrared laser, a scattered light signal acquisition control system, event-related optical signal processingsoftware and lie detecting software, and plays a main role in acquiring objective data that whether a testee is honest to respond to detecting stimulation.

Description

technical field [0001] The present invention relates to an event-related optical signal (Event-Related Optical Signal, EROS) acquisition and analysis system and its lie detection method, in particular to national security, public security, justice and the recognition technology and identification of honesty and deceitful behaviors of parties involved in civil disputes method. Background technique [0002] At the beginning of the 20th century, as a method of basic research in physiology and medicine, the multi-conductor physiological recording technology for recording changes in blood pressure, respiration and skin electricity came out, and was soon used for lie detection. After nearly a hundred years of use, common sense and experience Based on the development of the traditional polygraph technology widely used in many countries in the world. Traditional polygraph technology is based on the common sense that people tell lies often accompanied by heartbeat, blushing and swea...
