This webpage provides clarifications on the types of medical information listed in the Personal Data Protection (Notification of Data Breaches) Regulations 2021.

In 2021, the Personal Data Protection Commission (PDPC) introduced the Personal Data Protection (Notification of Data Breaches) Regulations that set out mandatory data breach notification requirements. These include a list of prescribed classes of data deemed to be of significant harm to the affected individuals (“whitelist”) and would therefore be subject to breach notification requirements, as well as how organisations shall notify affected individuals and relevant authorities in the event of a data breach.
