Japan to test phones which will alert if it sounds like you are being scammed

Young girl on phone. Image from ShutterstockFujitsu and the Nagoya University will begin field trials for phone scam detection technology sometime this month, the organisations announced on Friday.

The scam detection system, which was first announced in March, claims to be able to recognise a phone scammer by combining voice intonation analysis with keyword recognition.

Japan's elderly population is frequently victimized by phone scams, with criminals often posing as acquaintances or authority figures such as police or lawyers.

When criminals pose as acquaintances, they often try to convince their targeted victims that they're in trouble and need money transferred to an account to bail them out.

The system works by detecting the changes in the voice pitch and levels that are common in the intonations of stressed-out victims, by recognising typical words used by voice scammers - "indebtedness," "compensation," "debt," or "repayment," for example - and by alerting family members or others that something's up.

As person becomes stressed their vocal range flattens

Fujitsu and Nagoya University will equip landlines with detection devices in 100 Okayama Prefecture homes.

When a possible scam occurs, the alarm messages will go out to family members, the police, the bank, and Fujitsu.

On receiving the message, family members will contact the participant and ask what happened, to determine whether the call was in fact a scam.

Meanwhile, the police will immediately visit the participant's house to assess the situation.

Simultaneously; the bank will temporarily halt payment transactions from whatever account was designated by the participant for use in the trial. .

A scam call is detected

The trials will be carried out in collaboration with the Okayama Prefectural Police, the Okayama Pref. Information Communications unit of the National Police Agency's Chugoku Regional Police Bureau, and The Chugoku Bank.

The voice recognition part of the system might sound like eavesdropping, but Fujitsu promises that it's not.

Rather, the software ignores everything except the number of times a caller uses typical scam words, based on a keyword list provided by Japan's National Police Academy and on recordings of actual remittance-solicitation phone scams.

Overtrust occurs when victims are overwhelmed with distressing information and lose their powers of judgment.

Aa Fujitsu has described it, there are limits to human powers of perception and judgment. When overwhelmed with distressing information, some people, without knowing it, lose the capacity to objectively evaluate information provided by another party.

When overtrust occurs, victims tend to believe everything they're told - a situation that makes them vulnerable to getting fleeced by scammers.

It's not just the elderly who are susceptible, of course. The quick flash of a toy plastic police badge once caused me and a companion to hand over our wallets when we were touring Athens.

Fortunately, our scammers were overly greedy: they wanted more money than the pittance we had in our wallets and handed them back, asking to see our "hidden" money.

Our intonations and voice levels were likely steeped in stress.

Would you opt for a scam detection system? Would it feel intrusive?

I likely would, particularly were they to come up with a version I could wear around my neck when visiting foreign lands, where I emit the unmistakable aroma of clueless tourist.

    Nobody here? I have to compare this to a lie detector (Polygraph machine) used here by police. Since only one state in the union uses this device for court, its use should be dis continued. It works by graphing you biological information specifically blood pressure/rate, breathing rate and skin conductivity. What I thought most people know, but don't is that they don't work. Every serial killer in history ever put on a polygraph has passed with flying colors, as they just care so there is no change in the monitored information. With others they fail because somewhere in their mind they have a conflict or physical change (like squeezing a sphincter, which changes blood pressure) and they fail that question. I know a number of examiners (polygraph) that swear by the technology, but I know it doesn't work like they imagine. Most only answer correctly because they think it works...

    Basically I'm just saying that it is quite likely that a person that is careful, will trip the 'bad person' where there is no bad person. A truly bad person will not be detected. We shall see!

    I see another possible problem situation with this system. What if a legitimite debt collector calls, wouldn't some of those same watch words show up to the monitoring system? Words like 'debt', 'repayment', 'owe'? I would think that could put a new spin on the situation. What if the older parent doesn't want their children/relative to know they are behind on their bills/loan/mortgage? This system would detect those words and send a notification to the listed groups, and there is nothing amiss in this situation; instead the person's personal financial situation is just made more public by involving not just their relative that it contacted but also the bank and the police.
