Google Cloud and Swift Partner to Enhance Fraud Detection in Global Finance Using Privacy-Preserving AI

Google Cloud and Swift Join Forces to Combat Financial Fraud

In a significant move to enhance the security of global financial transactions, Google Cloud and Swift have announced a partnership to develop an innovative, privacy-preserving AI solution for financial institutions. The collaboration, set to launch in the first half of 2025, aims to leverage federated learning techniques to improve fraud detection in cross-border payments without compromising data privacy 1

The Power of Federated Learning

At the heart of this initiative is the use of federated learning, a cutting-edge AI approach that allows collaborative model training without the need to share sensitive data. This technique enables financial institutions to contribute to a global fraud detection model while keeping their proprietary data secure and confidential 2

Rachel Levi, head of AI at Swift, emphasized the importance of this technology, stating, "This exploration will help the community validate whether federated learning technology can help financial institutions stay one step ahead of bad actors through sharing of fraud labels, and in turn enabling them to provide an enhanced cross-border payments experience to their customers" 1
