Personal Data Protection Act, biometric data definition and sensitive category
Act 709 (Malaysia) s.4, as amended by Act A1727 s.3, in force 2025-04-01official Act A1727 amendment text, Department of Personal Data Protection (pdp.gov.my)
In force since 1 April 2025. Binds private bodies.
What this law does
Act A1727 s.3 inserted a dedicated biometric data definition into s.4 (any personal data resulting from technical processing relating to a person's physical, physiological, or behavioural characteristics) and added biometric data to the sensitive personal data list immediately after the offence-related category.
Both a faceprint and a voiceprint fall squarely within physical, physiological, or behavioural characteristics resulting from technical processing, which is exactly how a voice or face embedding is produced. Both are now, in force, sensitive personal data under s.4, requiring explicit consent under s.40's stricter processing conditions. No biometric-specific retention or destruction duty distinct from the Act's general data-minimisation and accuracy principles was found.
