Answer:

A Data Fiduciary determines the purpose and means of processing personal data. There are generally two types under the Act: standard Data Fiduciaries and Significant Data Fiduciaries (SDFs). SDFs are notified by the government based on data volume, sensitivity, and risk, and they face stricter compliance requirements like appointing a DPO and conducting periodic audits.
