A digital identity-based approach to protecting customers from fraud works and has been proven. NTT DOCOMO made various efforts, and in two years, the amount of damage has reduced to about 1/20.

NTT DOCOMO determined its digital identity guidelines in 2020-2021, which defined dIAL, dAAL, and dFAL. dAAL3 requires anti-phishable MFA, and services implementing dAAL3 have demonstrated remarkable achievements in reducing fraud and unauthorized payments in the past years. Passkeys are the obvious key driver for authentication.

In addition, NTT DOCOMO addresses online and offline identity proofing by utilizing My Number individual cards with the IC-chip capability, which has now become available on smartphones. Recent features for d ACCOUNT [openID-based account] help account recovery, dramatically reducing the number of calls to a customer center.
