BDI Clarifies Data Integrity of 'Tang Rat' and 'Health Link' Systems

On July 31, 2026, the Big Data Institute (BDI) issued a clarification regarding the operational nature of the 'Tang Rat' application and the 'Health Link' system. According to Matichon Online, the BDI emphasized that these platforms function primarily as display interfaces for health information rather than as databases where original records are modified.

For residents and travelers utilizing these digital services, the BDI’s statement serves to clarify that the information presented is pulled directly from the source agencies. Consequently, the platforms do not possess the authority or technical function to alter medical data at their level. If a user identifies discrepancies in their health records, the BDI indicates that the correction process must be handled by the original issuing agency rather than through the application interface itself.

This distinction is important for those relying on these systems for digital health verification or record-keeping, as it underscores that the platforms act as a conduit for data visualization. While the BDI has confirmed the role of these systems, it remains to be seen how the government will streamline the process for users to request corrections from the various source agencies if errors are discovered. Users are advised to verify their information directly with their healthcare providers or the relevant issuing authorities to ensure accuracy.
