The world’s first technology to analyze phone conversations for the purpose of detecting telephone scammers has been developed by Japanese researchers at Nagoya University and Fujitsu.
This software runs on a mobile phone and so far has achieved a 90% success rate at detecting phishing and other similar phone scams.
The situation is called “overtrust,” occurring when one individual, as judged by voice pitch and volume, is stressed out and more susceptible to scams.
This diminished capacity to objectively evaluate information provided by another party often occurs when an individual is overwhelmed with distressing information. This explains why phone scammers warn about encroaching viruses or claim that a relative has died.
The researchers have focused on this aspect, and the new software can detect when a phone user may not be able to objectively evaluate the third party’s side of the conversation.
The astounding rate of accuracy is the result of a very specific strategy. Researchers were able to identify the most common keywords scammers use by studying recordings of real phone scams.
Two of the more common ones include, for example, “indebtedness” or “compensation.” With the help of voice recognition software, the caller’s conversation is scanned for these particular keywords.
The quality of “overtrust” present in the pitch and tone in the voice of the potential victim (or mark) is also assessed.
The software does not record phone calls, and is word-specific. It ignores everything except the keywords indicated on a pre-registered list.
The detection software’s function is limited to analyzing the waveform of one’s voice, not the actual spoken words.
If a scam is detected, an alert is sent to the victim, as well as a family member or “objective third-party member.”
The National Police Academy and the Bank of Nagoya have expressed great interest in the success of this technology and are now moving forward with real-world trials.
It is believed that this software could eventually be built into every smartphone.
The days of mobile phone scammers may well be numbered, but the dynamic nature of technology may well provide loopholes for those who seek to invade the privacy of others and profit from it.
