Law on Personal Data Protection, biometric data definition
Article 4 distinguishes specific personal data (the sensitive category) from general personal data, listing biometric data among health data, genetic data, criminal records, children's data, and personal financial data. The official elucidation to Article 4(2)(b) defines biometric data as data relating to a person's physical, physiological, or behavioral characteristics enabling unique identification, naming a facial image expressly as an example alongside fingerprint, retinal, and DNA data.
A direct search for suara (voice) in the elucidation returned zero hits, so voiceprint coverage rests on the general definitional language rather than an express example. As specific personal data, biometric data processing requires stricter consent under Article 21 and related provisions.
