AI Polygraph Is Better At Detecting Lies Than You - Geek Posted: 19 Mar 2019 07:54 AM PDT Some people are natural liars, while others have no poker face. But it doesn't take much to fool someone in blind computer conversations. In an attempt to remove those blinders, Florida State University researcher Shuyuan Ho has developed the first online polygraph test. "You could use it for online dating, Facebook, Twitter—the applications are endless," Ho, an associate professor in the College of Communication and Information, said in a statement. "I think the future is unlimited for an online polygraph system." Imagine a future where technology can automatically identify liars and truth-tellers based on the words they type in electronic messages. In a study published by the journal Computer in Human Behavior, Ho detailed the findings of an online game created to measure truthful and deceptive communication between people. Players were randomly assigned the role of "Saint" or "Sinner," then left to have a computerized chat. Researchers, meanwhile, followed along, using machine learning tech to scrutinize patterns of words and writing. Just as physical cues provide context, so, too, do language-action cues in written text. Lying sinners were less expressive but used more ornamental words, displayed more negative emotions, and appeared anxious when communicating with truth-tellers. Conversely, saints tended toward speculation, taking longer to respond to inquiries; sincere players provided more reasoned ideas and expressed more reflective thinking, according to the study. Ho's experiment highlighted that while a human can spot lies in messages about 50 percent of the time, the machine-learning approach has a much higher success rate of 85 to 100 percent. "I want to get the world's attention on this research so we can hopefully make it into a commercial product that could be attached to all kinds of online social forums," she said. "I think we all have good common sense about the people we meet face to face, but how much common sense do we have with the strangers we encounter online where you can meet a lot of people very fast," Ho continued. "This research is so important because it can provide another reference point offering more protection. All of society can benefit." More on Geek.com:

UPDATE: Polygraph tests ordered for several St. Martinville city employees - KATC Lafayette News Posted: 18 Mar 2019 03:16 PM PDT The St. Martinville City Council is still working to hire a polygraph company to test several city employees after the Public Works Superintendent Charles Radar was accused of using a racial slur during a meeting with employee Michael Martin. Last week, the council was split on a proposal to polygraph those involved and witnesses to the incident. They say they want the polygraph done because of conflicting stories. Mayor Melinda Mitchell was the tie-breaking vote. The Mayor's office reached out to three different public agencies to see if they would conduct the test. Mitchell said the city check with Louisiana State Police, the New Iberia Police Department and the Lafayette Police Department. "Each agency declined because they only use it to conduct criminal investigations," said Mitchell. Mitchell said they are looking to hire a private company out of Lafayette. Right now, the St. Martinville city attorney is reviewing paperwork from the company.

Upcoming Online Polygraph to Help Spot Liars on Facebook & Tinder - The Quint Posted: 19 Mar 2019 11:41 PM PDT Is your Tinder date trustworthy? Scientists are developing an online polygraph that could spot liars from the words they write on their internet dating profiles, Facebook messages or Twitter posts. It is tricky enough to identify a lie in face-to-face conversations that offer facial expressions, gestures and tone of voice because those physical cues add context. Spotting a liar gets even tougher in blind computer conversations, said Shuyuan Ho from Florida State University in the US who wants to shed those blinders. "The future of my research is an online polygraph that could be used many different ways," Ho said in a statement. "You could use it for online dating, Facebook, Twitter -- the applications are endless. I think the future is unlimited for an online polygraph system," she said. Ho envisions a future where technology can identify liars and truthtellers based on the words they write in electronic messages. Her research dove into the murky depths of internet deception where trolling, identity theft and phishing for credit card numbers snag an increasing number of online users. The study, published in the journal Computers in Human Behavior, detailed the findings of an online game that she created to measure truthful and deceptive communications between two people. Ho parsed the words in those conversations, hoping to extract context from millions of bits of data in many messages -- described as language-action cues -- just as people get context from seeing physical cues that indicate whether someone is telling the truth or lying. The experiments revealed a person could spot lies in messages about 50 per cent of the time, while a machine-learning approach could identify deception with an accuracy rate ranging from 85 to 100 per cent. "This basic research offers great potential to develop an online polygraph system that helps protect our online communication," Ho said. Researchers created an online game designed to identify language cues that unmask deceivers and truthtellers. The game randomly assigned players to play the roles of "The Saint" and "The Sinner." As sinners and saints interacted via computers, researchers captured those conversations and used machine-learning technology to scrutinise patterns of words and writing. Some fascinating language tendencies emerged from that analysis. The lying sinners were found to be less expressive, but they used more decorative words per message. They displayed more negative emotions and appeared more anxious when they communicated with truthtellers. Deceivers also took less time to respond and used more words of insight, such as "think" and "know," and they tended to use more words of certainty, including "always" or "never." Conversely, truthtellers used more words of speculation, such as "perhaps" and "guess," and they took longer to respond to inquiries. These saints provided more reasoned ideas by using words of causation such as "because". They expressed more reflective thinking with words like "should" and "could." Researchers also calculated time lags between every sentence, and even parts of a sentence, by placing time stamps on the words. That precise breakdown clearly showed how much a person paused during interactions -- another language-action cue. Those pauses might have been so slight that they would not necessarily be noticeable to a person, but machine-learning technology could spot it. Ho said she hopes her research will eventually give people better protection when they are online.

CBI conducts polygraph test of Kalabhavan Mani's friends - Onmanorama Posted: 19 Mar 2019 10:57 PM PDT Mani was found dead on 6 March 2016. The CBI took over the case after his relatives alleged foul play. Kochi: CBI's polygraph tests in Kalabhavan Mani death case have begun. The tests which started on Tuesday morning continued late night. Mani's former manager Joby Sebastian, friends MG Vipin and C Arun underwent the test held at CBI office in Kathrikadavu. Forensic experts from Chennai are conducting the tests. The CBI requested polygraph test after suspects' statements at CJM Court, Ernakulam. The court had granted permission to test all seven suspects. Mani's friends Murugan and Anilkumar, and film stars Jaffar Idukki and Sabumon too will be subjected to polygraph test. Mani, 45, who acted in some 200 films in Malayalam and other languages, was admitted to a hospital in Kochi on March 4, 2016 for an alleged liver ailment. He died two days later. Mani was staying in a 30-acre farmhouse near Chalakkudy, away from his home, his wife and daughter, where these friends were believed to be present on the day the late actor fell ill. After his death, the hospital authorities reported the presence of an organophosphate pesticide in the body, leading to speculation that Mani might not have died a natural death. Ever since, his family has been running from pillar to post to ascertain the real cause. In 2018, the Kerala government too sought a CBI probe. The CBI took over the case after his relatives alleged foul play. The CBI's task is to ascertain how the pesticide got inside his body.
