anti-phone fraudster tech
I believe you mean anti-phone-fraudster tech (or anti-fraudster phone tech, if you'd prefer.) I don't thing Fujitsu would want to be considered to be anti-phone, or involved in any form of fraudster tech...
Fujitsu and Nagoya University have kicked off a month-long trial of new technology designed to raise the alarm when it thinks the recipient of a phone call is being scammed by a fraudster. The trials will take place in Okayama Prefecture in collaboration with local and regional police and the Chugoku Bank, according to Fujitsu …
The higher number of older people who are disproportionately asset rich might have something to do with it. Japanese police are not generally corruptible in the way suggested here. Organised crime being traditionally another matter. However phone fraud is not mainstream Yakuza business.
With Raku-Raku, Fujitsu has perhaps the world's leading mobile phone brand for senior citizens. 20MM units sold in Japan, exports planned. Since they have developed this tech, a cynic might say it is not surprising that domestic phone fraud would be highlighted as a big problem in Fujitsu's marketing material.
