In 2025, Hong Kong will implement the Regulation of Cross-border Data Flows Ordinance, which requires enterprises to be certified with Privacy Enhancing Technologies (PETs) when going to the cloud. Microsoft Azure Hong Kong and BioTrend launched the "AI Compliance Cloud", incorporating three innovative technologies:
1. Federal Learning Case
Lazada, the Southeast Asian e-commerce giant, has increased its click-through rate by 351 TP3T by jointly training cross-country recommendation models without sharing raw user data through the Tencent Cloud Hong Kong node.
Hong Kong insurer AIA leverages AWS' "Clean Rooms" service to analyze medical data in compliance with mainland hospitals, reducing policy pricing errors by 20%.
2. How USDT Payments Meet Audit Needs
Compliant cloud providers such as IBM Hong Kong support USDT payments and automatically generate chained audit trails that comply with section 88B of the Inland Revenue Ordinance. A CPA firm's field test shows a reduction of 60% in audit hours.
Trend Insight:
Gartner predicts that the 70% cross-border cloud service contract will include a Privacy-as-Code clause in 2025, and Hong Kong will be the preferred landing site due to legal compatibility.
