What are Open Finance Platforms in Japan?
Open finance platforms are digital platforms that enable the sharing and integration of financial data and services between different financial institutions, third-party providers, and consumers through open APIs (Application Programming Interfaces). These platforms facilitate access to financial data, such as banking, investments, insurance, and loans, allowing users to manage their financial portfolios and services from various providers in one centralized location. Open finance platforms often focus on improving financial transparency, providing personalized financial services, and enabling innovation in the financial sector through secure data sharing. By using these platforms, businesses and consumers can gain greater access to a wide range of financial services and products, while also enhancing competition and promoting financial inclusion.

NetGuardians
NetGuardians
As payment channels have multiplied, so have the routes open to fraudsters; increasing banks’ potential liabilities. Adoption of real-time payments, Open Banking and digital-led interactions exacerbates these problems. Traditional anti-fraud practices find it all but impossible to efficiently prevent payment fraud. Most rely on hundreds of static, reactive rules that fail to detect new fraud patterns and trigger too many poor hits. Leveraging award-winning 3D artificial intelligence (3D AI) technology, NetGuardians’ platform NG|Screener monitors all of the bank’s payment transactions in real-time catching more fraud with fewer false positives. It identifies suspicious payments coming from social engineering techniques or scams (such as invoice redirection, love scams, CEO-fraud) and ties this in with digital banking fraud indicators (such as eBanking/mBanking sessions redirected by malware, hijacked by hackers or account takeover fraud resulting from identity theft). -
