Case Study: Jibun Bank achieves stronger mobile transaction security with OneSpan Mobile Security Suite

Japanese Bank Secures Online & Mobile Banking With Transaction Signing Solution

Jibun Bank, a “Smartphone Bank” joint venture of KDDI Corporation and The Bank of Tokyo-Mitsubishi UFJ, needed to strengthen authentication and enhance countermeasures against rapidly evolving online fraud to protect mobile transactions in its single mobile banking application. To add transaction signing security without impeding user convenience, Jibun Bank selected OneSpan and deployed the OneSpan Authentication Server Framework together with the OneSpan Mobile Security Suite.

OneSpan implemented an in‑app transaction signing solution that transmits transaction values seamlessly so customers don’t have to type details or carry additional devices, with instantaneous activation. The OneSpan solution defeated man‑in‑the‑browser and refined online fraud (including PC-initiated attacks) and delivered smarter, more secure services while preserving ease of use—an outcome Jibun Bank says made it among the first to offer electronic transaction signing in a mobile banking app.
