Ant International Upgrades Alipay+ With Privacy-Enhancing Tech
Ant upgrades Alipay+ cross-border wallet with end-to-end encryption in processing, expanding privacy tech, research partnerships, and global data-transfer certifications to support AI-enabled services.

Ant International announced an upgrade to the Alipay+ cross-border wallet that deploys privacy-enhancing technologies to keep transaction data encrypted during processing. The update covers all core Alipay+ operations used by about 150 million merchants and 1.8 billion consumer accounts and aligns with Singapore’s PDPC guidance, while Ant expands research with NTU Singapore on digital trust. Building on a multi-year privacy program, Ant has open-sourced privacy tools such as SecretFlow and an MPC library and established a privacy computing fund. In IMDA’s Privacy Enhancing Technology Sandbox, Ant tested a model trained on partner data without exposing sensitive information, and the company is pursuing CBPR/PRP certifications to streamline overseas data transfers and bolster its US-market expansion.
