Global Signal Exchange joins Japan anti-scam alliance

Global Signal Exchange has formed a partnership with the Japan Anti-Scam Alliance, linking the UK-based non-profit with a newly created Japanese anti-fraud group.

The alliance was launched as a public-private effort to tackle online fraud in Japan, backed by major technology companies and Japanese banks. The partnership expands Global Signal Exchange's work with law enforcement and industry groups in other markets, including the UK, Singapore and Australia.

Global Signal Exchange, or GSE, describes itself as a clearing house for threat signals shared across sectors. It was launched in January 2025 as a non-profit owned by Oxford Information Labs, with Google as a co-founder.

Its network tracks more than 1 billion threat signals in real time, according to the organisation. Members include companies such as Google, Meta and Microsoft, alongside public sector bodies and other private organisations.

Japan link

The new arrangement is designed to connect Japanese banks, technology groups, security organisations and law enforcement bodies with GSE's wider international network. It comes as authorities and businesses in several countries seek faster ways to identify and disrupt online scams, which often span multiple jurisdictions and rely on fragmented data sources.

GSE has recently worked with a range of bodies, including Cifas in the UK, Somos in the telecoms sector, the Australian Competition and Consumer Commission in Australia, and the National Crime Agency in the UK. It has also cited work in Asean states in East Asia.

Lucien Taylor, Co-Founder and Chief Technology Officer at Global Signal Exchange, outlined the rationale for the latest partnership.

"Our partnership with the newly launched Japan Anti-Scam Alliance connects Japanese banking, technology, security and law enforcement organisations with the rest of the world through the Global Signal Exchange. JASA knows Japanese business best, and this pilot builds on our work in other regions and sectors, including Asean states in East Asia, Cifas in the UK, Somos in the telecoms industry, the ACCC in Australia, and the NCA with UK law enforcement. The success of GSE in helping to fight fraud depends on the seamless interconnectedness of these force multipliers," Taylor said.

Shared data

GSE's model centres on sharing abuse data and threat signals between public and private organisations in real time. The aim is to make it easier for participants to identify the infrastructure and supply chains used to deliver scams, fraud and other forms of cybercrime.

Bringing together signals from different sectors can make the facilitators of cybercrime more visible, according to the organisation. That reflects a wider push across financial services, technology and law enforcement to improve data-sharing as criminals move quickly between online platforms, telecoms networks and banking channels.

The Japanese alliance adds another national framework to that effort. By linking a domestic anti-scam body to an international exchange, the partnership is intended to reduce barriers created when intelligence is held separately by banks, internet companies, telecoms operators and investigators.

Taylor said the broader objective was to create a more connected international system.

"Through GSE, we are building an international community with a shared commitment to advancing information-sharing and collaboration. This year's Anti-Scam Conference in Japan was another step forward, and we look forward to working closely with the Japan Anti-Scam Alliance. It will help replace fragmentation with a more joined-up approach to real-time data-sharing and collaboration. The conference has helped build a strong cross-industry, public-private shield for the digital space, and GSE will continue to work with community members and partners to drive decisive action that turns the tables on scammers," Taylor said.

Oxford Information Labs owns GSE, which operates from the UK as a non-profit. Its role is to provide real-time insight into the networks that support scams and fraud by combining as many data sources as possible, according to the organisation.

The Japan Anti-Scam Alliance was established to coordinate action against online fraud in the country. Its partnership with GSE places that domestic effort within a wider international data-sharing network spanning technology companies, financial institutions and law enforcement bodies.
