Notaries as public officials who are authorized to make authentic deeds carry out their duties and authorities inseparable from the processing of Personal Data, both physical and electronic. Notaries process Personal Data not only for Personal Data subjects, namely Clients, but also for workers or interns, or third parties whose information is provided by the Client. Since the enactment of the PDP Law, Notaries as officials who make authentic deeds in processing Personal Data are not only obliged to maintain the confidentiality of Personal Data, but there are also several other obligations regulated in the PDP Law as an effort to prevent and eradicate potential cybercrime. In this study, the author will dissect the role and obligations of Notaries in the security of Personal Data based on the PDP Law. The study used a normative legal method with a statutory approach and a conceptual approach. Through this study, it is concluded that a Notary as an official who makes authentic deeds has a crucial role, namely as a Personal Data Controller who can determine the purpose and method of processing personal data.
