A Significant Data Fiduciary (SDF) is a classification under the DPDP Act for Data Fiduciaries that the Central Government of India may designate based on factors such as the volume and sensitivity of personal data processed, risk to the rights of Data Principals, potential impact on the sovereignty and integrity of India, risk to electoral democracy, security of the state, and public order.
Significant Data Fiduciaries face additional obligations beyond those of regular Data Fiduciaries, including appointing a Data Protection Officer who is based in India and represents the SDF, appointing an independent data auditor to evaluate compliance, conducting periodic Data Protection Impact Assessments, and undertaking periodic audits. These enhanced requirements recognize that organizations processing large volumes of data pose greater risks to individuals and society.
