Artificial intelligence tool used to catch people who lie to the police


Artificial intelligence tool used to catch people who lie to the police

 A new computer tool will help the police trap liars 

By Martin Evans, crime correspondent 7 JANUARY 2019 • 7:00AM

British scientists have developed a new computer programme that can spot if someone has lied to police about being robbed.

The groundbreaking software analyses the wording of a victim's statement in order to identify tell tale signs of fake reports.

Spanish police, who have been using the tool, found it was successful in more than 80 per cent of cases helping them to identify 64 false reports in just one week.

Developed by experts at Cardiff University, VeriPol, uses a combination of automatic text analysis and artificial intelligence to recognise when somebody has been lying or exaggerating to the police.

Thousands of false reports are submitted to the police each year with many perpetrators hoping to receive inflated insurance payouts or claims for crimes that never happened in the first place.

But according to the researchers there are certain tell-tale signs contained in written statements which can be quickly identified by the new software.

Using algorithms the machine is able to carefully analyse various features in the text, such as adjectives, acronyms, verbs, nouns, punctuation marks and numbers.

Experts claim a false statement is more likely to contain certain traits and giveaway signs, that can be spotted using artificial intelligence. 

It is thought false statements are more likely to be shorter than genuine ones and focus on the details of the stolen property rather than the incident itself.

They are also thought to be lacking in certain details about the perpetrator and the attack itself.

The team behind the technology believe it could help police forces save valuable time and effort in investigating fake crimes and will also help deter people from filing false reports in the first place.

Dr Jose Camacho-Collados, from Cardiff University’s School of Computer Science and Informatics, who helped develop the technology, said: “Our study has given us a fascinating insight into how people lie to the police, and a tool that can be used to deter people from doing so in the future.

“Police officers across Spain are now using VeriPol and integrating it into their working practices. Ultimately we hope that by showing that automatic detection is possible it will deter people from lying to the police in the first instance.”

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke...

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that th...

New ATM's: withdraw money with veins in your finger

New cash machines: withdraw money with veins in your finger Cash machine technology that reads the pattern of finger veins is already available in Japan and Poland   By Telegraph Reporters 6:59PM BST 15 May 2014 Cash machines could soon be installed with devices that identify customers by reading the veins in their fingers. The technology is already being rolled out in Poland, where 1,730 cash machines will this year be installed with readers, negating the need for a debit card and Pin. Developed by Hitachi, the Japanese electronics firm, the machines read the patterns of the veins just below the surface of the skin on your finger using infra-red sensors. The light is partially absorbed by haemoglobin in the veins to capture a unique finger vein pattern profile, which is matched to a profile. The technology is used by Japanese banks and also in Turkey, offering “groundbreaking levels of accuracy and speed of authentication”, Hitachi said, which in t...
