Fujitsu and Toyo University study how to protect the elderly from phone fraud

fujitsu and the Toyo University are carrying out a joint research project in Japan, with the collaboration of the Japanese city of Amagasaki, focused on find out how seniors can be protected from phone scams. To do this, the project will use converging technologies and combine Artificial Intelligence techniques and psychological research on the state of the victims of these and other types of scams.

The objective pursued by this project is to develop an Artificial Intelligence model capable of detecting various types of telephone fraud to be used in the prevention of scams aimed at the elderly and other vulnerable groups. The project went live in the middle of last February and ended at the end of March, when Fujitsu, Toyo University and the city of Anasagaki simulated realistic fraud scenarios in field tests with elderly people in the city. Specifically, with twenty volunteers.

Based on a previously generated phone fraud scenario, a phone call with a pre-recorded voice was made to each of the volunteers to simulate the calls made by groups of scammers. Fujitsu’s human sensing technologies have been used in the simulation to detect changes in human emotions.

Specific, AI Activator and an AI technology to recognize facial expressions to detect emotional changes. This has been done using in parallel with a methodology designed to measure and scale human emotions, designed by Toyo University. After the calls, the test participants answered a questionnaire to measure their emotional state during the test.

Based on data and perceptions obtained in these tests, the three parties are carrying out new verification tests, which will conclude before the end of the first half of this year 2022. The objective of this phase is to determine the accuracy of the Artificial Intelligence model. of Fujitsu to detect telephone fraud, a growing social problem, and which according to the National Police Agency of Japan, in 2021 made those over 65 years of age represent 88.2% of the cases of telephone fraud detected in the country.

Toyo University will analyze the actual data of the test participants and compare it with the results of the questionnaire to identify the relationship between the physical and emotional state of the participants. Fujitsu will then use the analysis to generate the aforementioned model, which will be based on the characteristics of the participants who were deceived during the simulations. Subsequently, a second test has been carried out with the model to confirm its accuracy in detecting fraud. By the end of 2022, Fujitsu hopes to have ready an AI model capable of detecting various types of scams telephone calls with great precision.
