Two men on motorbikes approached a broken-down vehicle in Caracas one day earlier this month in what could have been a nightmare scenario in one of the world’s most dangerous cities where roadside robberies and murders are an everyday occurrence.

The men took up positions either side of the green four-wheel-drive vehicle, with a 33-year-old female schoolteacher behind the wheel, and guarded it until a tow truck arrived two hours later to cart it off to a garage.

The two guards are employees of a new mobile application called “Pana” – “Buddy” in Venezuelan slang – which dispatches security crews to stranded drivers who request help.

It’s a reflection of how Venezuelans are turning to technology to overcome the dangers and nuisances of living in the crisis-hit country. Mobile payment apps, for example, attract customers who do not have enough paper money, which is in short supply due to hyperinflation.

Domingo Coronil who started Pana with his brother Juan Cristobal last September said they have carried out more than 5,000 successful driver rescues on the streets of the capital.

“People’s reactions have been amazing. Some start crying, while others take selfies,” the 46-year-old security consultant said in an interview.

Violence in Venezuela has shot up during the oil-wealthy country’s spiral into a five-year economic crisis and political meltdown. Many Caracas residents refuse to go out at night due to security fears, and wealthier Venezuelans often travel in bullet-proof cars with bodyguards.

There were almost 27,000 violent deaths in the country last year, with Venezuela having the second highest murder rate in the world after El Salvador, according to the Venezuelan Observatory of Violence, a local crime monitoring group.

National homicide rates rose each year from 67 murders per 100,000 people in 2011 to 92 in 2016, before dipping to 89 last year, according to the group.

The homicide rate in Caracas alone was 104 per 100,000 people in 2017, the group said. New York, in contrast, had a homicide rate of 3 per 100,000 last year and most European cities had less than 1.

A recent Gallup study placed Venezuela at the bottom of its 2018 Law and Order index, with 42 percent of surveyed Venezuelans reporting they had been robbed the previous year and one-quarter saying they had been assaulted.

“The fear people have isn’t you’ll be robbed in your car, but that you’ll be killed or kidnapped,” said Roberto Briceno Leon, the observatory’s director.

Venezuelan authorities say nongovernmental groups inflate crime figures to create paranoia and tarnish President Nicolas Maduro’s socialist government. But even the most recent official national murder rate – 58 per 100,000 inhabitants for 2015 – was still among the world’s highest.

About 700 people have joined Pana because of the high crime rate, Coronil said, each paying an annual fee of 4,800,000 bolivars, or about $2 to $4 on the black market, to request help as many times as they want at any hour day or night.

The company receives a customer’s geo-locations at its headquarters and dispatches two of its 28 security guards to the breakdown. Coronil hopes to expand coverage to roads outside Caracas and offer corporate plans.

Vanessa Mikuski, the schoolteacher in the van, tapped the button in Pana’s smartphone app when her car broke down without warning that June morning in the east of Caracas. A friend had recommended she download it last year.

The two Pana security guards, who were not armed and wear jackets with the app’s logo, kept pedestrians and drivers away while Mikuski waited and arranged for her children to be picked up from school.

“You feel much more secure … And at that price, it’s great,” she said.

When Neha Maldar testified against the traffickers who enslaved her as a sex worker in India, she spoke from the safety of her own country, Bangladesh, via videoconferencing, a technology that could revolutionize the pursuit of justice in such cases.

The men in the western city of Mumbai appeared via video link more than 2,000 km (1,243 miles) west of Maldar as she sat in a government office in Jessore, a major regional hub for sex trafficking, 50 km from Bangladesh’s border with India.

“I saw the people who had trafficked me on the screen and I wasn’t scared to identify them,” Maldar, who now runs a beauty parlor from her home near Jessore, told Reuters. “I was determined to see them behind bars.”

“I told them how I was beaten for refusing to work in the brothel in the beginning and how the money I made was taken away,” she said, adding that she had lied to Indian authorities about her situation after being rescued, out of fear.

Thousands of people from Bangladesh and Nepal — mainly poor, rural women and children — are lured to India each year by traffickers who promise good jobs but sell them into prostitution or domestic servitude, anti-slavery activists say.

Activists hope the safe, convenient technology could boost convictions. A Bangladeshi sex trafficker was jailed for the first time in 2016 on the strength of a victim’s testimony to a court in Mumbai via video link from Dhaka, Bangladesh’s capital.

Convictions for cross-border trafficking in the region are rare as most victims choose not to pursue cases that have traditionally required them to testify in Indian courts, which meant staying in a shelter for the duration of the trial.

“They have always wanted to go back home, to their families,” said Shiny Padiyara, a legal counsel at the Indian charity Rescue Foundation that has facilitated videoconferencing cases and runs shelters for trafficking victims. “And most never return to testify.”

But videoconferencing is making it easier to pursue justice. Survivors have given statements, identified their traffickers, and been cross examined in at least 10 other ongoing international cases in Bangladesh, advocates said.

“Enabling victims to testify via video conference will lead to a possible decrease in acquittal rates for want of prime witnesses,” said Adrian Phillips of Justice and Care, a charity that supports the use of video testimony to help secure justice.

Even then, it is tough. During Maldar’s three-hour deposition, she withstood a tough cross-examination, showed identity documents to prove her age and countered allegations by the defense lawyer that she was lying about her identity.

‘Unpardonable’

Tara Khokon Miya is preparing her 27-year-old daughter to testify against the men who trafficked her to India from Dhaka, where she had been working in a garment factory.

“I almost lost my daughter forever,” she said, sitting in her home in Magura, less than 50 km from Jessore, describing how she disappeared after work and was taken to a brothel in India, and raped and beaten for almost a year before being rescued.

“What the traffickers did to my daughter was unpardonable,” Miya said, wiping her tears. “We seek justice. I nurtured her in my womb and can’t describe what it felt like to not know about her whereabouts.”

The trial has been ongoing since 2013 when the young woman, who declined to be named, was repatriated. The charity Rights Jessore is helping the family through the process, by providing counseling and rehearsing cross-examination.

“The best thing is her father will be by her side when she talks in court,” Miya said, finally breaking into a smile.

India signed a bilateral agreement with Bangladesh in 2015 to ensure faster trafficking investigations and prosecutions, and with Nepal in 2017, and laid down basic procedures to encourage the use of videoconferencing in court proceedings.

“The procedure is very transparent,” said judge K M Mamun Uzzaman at Jessore courthouse, which often converts its conference hall into a courtroom for videoconferencing cases to protect survivors’ privacy.

“I’m usually present and victims are able to testify confidently … it is easy and cost effective for us,” he said. “But the biggest beneficiaries are the survivors.”

The future

Videoconferencing in Bangladesh has been plagued by technical glitches such as power cuts and poor connections.

“Sometimes the internet connection is weak or it gets disconnected during the testimony,” said Binoy Krishna Mallick head of Rights Jessore, a pioneer in using this technology to encourage trafficking survivors to pursue justice. “But these are just teething troubles.”

The bigger challenge, activists say, is to ensure survivors remain committed to the trial despite delays caused by a backlog of cases and witnesses’ failure to appear to testify.

Swati Chauhan, one of the first judges to experiment with video testimony in 2010, is convinced that technology can eliminate many of these hurdles.

“Victims go through a lot of trauma, so it is natural that they don’t want to confront their trafficker in a court — but that doesn’t mean they don’t want the trafficker to be punished,” she said. “A videoconference requires meticulous planning and it is not easy coordinating between departments and countries. But it is the future for many seeking justice.”

Laura was barely 18 when a palm reader told her she could make $180 a month working in beetroot farms in Russia — an attractive sum for a girl struggling to make a living in the town of Drochia, in Moldova’s impoverished north.

That she had no passport, the fortune teller said, was not a problem. Her future employers would help her cross the border.

“They gave me a [fake] birth certificate stating I was 14,” Laura, who declined to give her real name, told Reuters in an interview.

That was enough to get her through border controls as she traveled by bus with a smuggler posing as one of her parents.

It was the beginning of a long tale of exploitation for Laura — one of many such stories in Moldova in eastern Europe, which aims to become the first country in the world to pilot blockchain to tackle decades of widespread human trafficking.

Trafficking generates illegal profits of $150 billion a year globally, with about 40 million people estimated to be trapped as modern-day slaves — mostly women and girls — in forced labor and forced marriages, according to leading anti-slavery groups.

The digital tool behind the cryptocurrency bitcoin is increasingly being tested for social causes, from Coca-Cola creating a workers’ registry to fight forced labor to tracking supply chains, such as cobalt which is often mined by children.

Moldova has one of the highest rates of human trafficking in Europe as widespread poverty and unemployment drive many young people, mostly women, to look for work overseas, according to the United Nations migration agency (IOM).

Due to the hidden nature of trafficking and the stigma attached, it is unknown how many people in the former Soviet country have been trafficked abroad but IOM has helped some 3,400 victims — 10 percent of whom were children — since 2001.

In Russia, Laura was forced to toil long hours, beaten and never paid. After ending up in hospital, she was rescued by a doctor, only to be trafficked again a few years later when an abusive partner sold her into prostitution.

She now lives with her daughter in a rehabilitation center in the northern village of Palaria with help from the charity CCF Moldova.

“I had a lot of suffering,” the 36-year-old said. “I am very afraid of being sold again, afraid about my child.”

​Scans and bribes

Moldova plans to launch a pilot of its digital identity project this year, working with the Brooklyn-based software company ConsenSys, which won a U.N. competition in March to design an identity system to combat child trafficking.

Undocumented children are easy prey for traffickers using fake documents to transport them across borders to work in brothels or to sell their organs, experts say.

More than 40,000 Moldovan children have been left behind by parents who have migrated abroad for work, often with little supervision, according to IOM.

“A lot of children are staying just with their grandfathers or grandmas, spending [more] time in the streets,” said Lilian Levandovschi, head of Moldova’s anti-trafficking police unit.

Moldova, with a population of 3.5 million, is among the poorest countries in Europe with an average monthly disposable income of 2,250 Moldovan Leu ($135), government data shows.

ConsenSys aims to create a secure, digital identity on a blockchain — or decentralized digital ledger shared by a network of computers — for Moldovan children, linking their personal identities with other family members.

Moldova has strengthened its anti-trafficking laws since Laura’s ordeal and children now need to carry a passport and be accompanied by a parent, or an adult carrying a letter of permission signed by a guardian, to exit the country.

With the blockchain system, children attempting to cross the border would be asked to scan their eyes or fingerprints.

A phone alert would notify their legal guardians, requiring at least two to approve the crossing, said Robert Greenfield who is managing the ConsenSys project.

Any attempt to take a child abroad without their guardians’ permission would be permanently recorded on the database, which would detect patterns of behavior to help catch traffickers and could be used as evidence in court.

“Nobody can bribe someone to delete that information,” said Mariana Dahan, co-founder of World Identity Network (WIN), an initiative promoting digital identities and a partner in the blockchain competition.

Corruption and official complicity in trafficking are significant problems in Moldova, according to the U.S. State Department, which last year downgraded it to Tier 2 in a watchlist of those not doing enough to fight modern day slavery.

Moldova is eager to prove that it is taking action, as a further demotion could block access to U.S. aid and loans.

​Tricked

Many details have yet to be agreed before the blockchain project starts, including funding, populations targeted, the type of biometrical data collected, and where it will be stored.

But the scheme is facing resistance from some anti-trafficking groups who say it will not help the majority of victims — children trafficked within Moldova’s borders and adults who are tricked when they travel abroad seeking work.

“As long as we don’t have job opportunities … trafficking will still remain a problem for Moldova,” said IOM’s Irina Arap.

Minors made up less than 20 percent of 249 domestic and international trafficking victims identified in 2017, said Ecaterina Berejan, head of Moldova’s anti-trafficking agency.

“For Moldova, this is not a very big problem,” she said, referring to cross-border child trafficking, adding that child victims may travel with valid documents as their families are in cahoots with traffickers in some cases.

But supporters of the blockchain initiative say low official trafficking figures do not account for undetected cases, and they have a duty to attempt to stay ahead of the criminals.

“Many times, authorities are late in using latest technologies,” said Mihail Beregoi, state secretary for Moldova’s internal affairs ministry. “Usually organized crime uses them first and more successfully. … Any effort [to] secure at least one child is already worth trying.”

An argumentative computer proved formidable against two human debaters as IBM gave its first public demonstration of new artificial intelligence technology it’s been working on for more than five years.

The new skills show that computers are getting better at mastering human language and speech.

The computer made its case for government-subsidized space research by pulling in evidence from its huge internal repository of newspapers, journals and other sources. After delivering opening arguments, the computer listened to a professional human debater’s counter-argument and spent four minutes rebutting it.

The company unveiled its Project Debater in San Francisco on Monday. IBM selected possible topics based on whether they were debatable, but neither the computer nor the human debaters knew the topic in advance. Nonetheless, the computer championed the topic fiercely with just a few awkward gaps in reasoning.

“Subsidizing space exploration is like investing in really good tires,” argued the computer system, its female voice embodied in a 5-foot-tall machine shaped like a monolith with TV screens on its sides. Such research would enrich the human mind, inspire young people and be a “very sound investment,” it said, making it more important even than good roads, schools or health care.

After closing arguments, it moved on to a second debate about telemedicine.

An IBM research team based in Israel began working on the project not long after IBM’s Watson computer beat two human quizmasters on a Jeopardy challenge in 2011.

But rather than just scanning a giant trove of data in search of factoids, IBM’s latest project taps into several more complex branches of AI. Search engine algorithms used by Google and Microsoft’s Bing use similar technology to digest and summarize written content and compose new paragraphs. Voice assistants such as Amazon’s Alexa rely on listening comprehension to answer questions posed by people. Google recently demonstrated an eerily human-like voice assistant that can call hair salons or restaurants to make appointments.

But IBM says it’s breaking new ground by creating a system that tackles deeper human practices of rhetoric and analysis, and how they’re used to discuss big questions whose answers aren’t always clear.

“If you think of the rules of debate, they’re far more open-ended than the rules of a board game,” said Ranit Aharonov, who manages the debater project.

IBM doesn’t try to declare a winner of the debates, but Noa Ovadia, one of the human debaters, said the computer was a formidable opponent even if it made a few too many blanket statements about space exploration being the pinnacle of human achievement.

Ovadia, a national debate champion in Israel, said she was impressed by its fluency in language and ability to construct sentences. She said the computer was able to “get to the bottom line of my arguments” and respond to them.

Among several outside experts IBM invited to attend Project Debater’s debut was Chris Reed, who directs the Centre for Argument Technology at the University of Dundee in Scotland. Reed said he was impressed by its grasp of “procatalepsis” — a rhetorical technique that involves anticipating an opponent’s argument and pre-emptively rebutting it.

As expected, the machine tends to be better than humans at bringing in numbers and other detailed supporting evidence. It’s also able to latch onto the most salient and attention-getting elements of an argument, and can even deliver some self-referential jokes about being a computer.

But it lacks tact, researchers said. Sometimes the jokes don’t come out right. And Monday, some of the sources it cited — such as a German official and an Arab sheikh — didn’t seem particularly germane.

“Humans tend to be better at using more expressive language, more original language,” said Dario Gil, IBM’s vice president of AI research. “They bring in their own personal experience as a way to illustrate the point. The machine doesn’t live in the real world or have a life that it’s able to tap into.”

There are no immediate plans to turn Project Debater into a commercial product, but Gil said it could be useful in the future in helping lawyers or other human workers make informed decisions.
