This study examines the legal protections for personal data security of holders of
Electronic Land Certificates, issued through Electronic Systems as Electronic Documents. The
digital shift requires public trust in the protection of personal data stored in electronic systems. Law
27/2022 on Personal Data Protection was enacted to protect the rights of personal data owners and
to specify the obligations of personal data controllers responsible for ensuring data protection. The
used writing approach is normative juridical, employing procedures for the collecting and analysis
of primary and secondary legal data. The research findings indicate that the Government, as a data
controller, has implemented measures to protect personal data by establishing procedures to secure
Electronic Certificates. The government is responsible for ensuring the security and confidentiality
of the Electronic Land Certificate owner's data against breaches.
