Quick answer
NTT Japan released an updated mobile app with FPoS authentication, enabling secure identity verification via My Number chip-based digital certificates.
Japan’s telecom giant Nippon Telegraph and Telephone (NTT) has launched an updated version of its mobile app, now supporting Federated Proof of Signature (FPoS) technology. This feature enables users to verify their identity using the My Number chip-based card—a digital equivalent of a passport with an embedded signature.
With this update, customers can generate digital certificates directly on their smartphones, simplifying access to personal accounts and contract signings. The technology ensures robust security, as digital signatures are verified through the government’s official system.
The update aims to optimize digital identity verification processes. According to developers, FPoS reduces fraud risks in online transactions while maintaining user convenience. While currently available only in Japan, the solution may be adapted for other markets in the future.
Common questions
- What is FPoS in mobile applications?
- Federated Proof of Signature (FPoS) is an authentication technology that verifies user identity using digital signatures integrated into government-issued ID cards, such as Japan’s My Number card.
- What are the benefits of using electronic certificates in the app?
- Electronic certificates provide high-level protection for accessing personal data and signing contracts, eliminating identity fraud risks while making verification faster and more convenient for users.
- Can this technology be used outside Japan?
- Currently, FPoS is designed for the Japanese market and integrated with the My Number system. Adapting it for other countries would require alignment with local identification standards.
