Polygraph tests have traditionally used physiological responses that are interpreted by the examiners, which are now getting the implementation of AI algorithms to make the test objective, minimize the examiner bias, and enhance accuracy. The many-to-one data sets can be analyzed in real-time in deception related systems using AI-integrated systems by reading complex pattern identification and probability based evaluation of the deception can be provided. Additional ways of measuring credibility in such systems include facial micro expression recognition, voice stress analysis, and behavior analysis, and this provides a more comprehensive and automated form of credibility determination. To give an example, today AI-enhanced enhanced platforms come with highly developed data visualization, automatic report generation, and remote monitoring capabilities. Law enforcement entities and the security companies are getting more interested in such hybrid systems in order to see more stable outcomes and improved legality of their efforts. AI-based lie detection devices are actively pursued by startups and technological companies to be implemented, and many of them can use wearable sensors and behavior analyses. This trend reflects the trend to digitization and automation of forensics interviewing that will permit the quicker, differentiated and defensible authority of assessment of the truthfulness. Since these ethical concerns and the admissibility in court are the barriers yet, the use of AI-enhanced polygraphs is also generating a discussion of how future legal and ethical standards and regulations should relate to truth verification.
