In cyber security, SPDI stands for Sensitive Personal Data or Information, a category of data that requires special protection under privacy laws.

Introduction

With rising digital transactions and data-driven services, protecting user information is a top priority. Certain types of personal information are considered more sensitive than others, requiring extra safeguards. This is known as SPDI (Sensitive Personal Data or Information). Understanding SPDI is vital for businesses, developers, and IT teams to comply with privacy regulations and maintain user trust.

SPDI Full Form Breakdown

  • S — Sensitive: Refers to critical or private information.
  • P — Personal: Tied to an identifiable individual.
  • D — Data: Information in digital or physical form.
  • I — Information: Knowledge or records about a person.

Together, SPDI refers to highly sensitive details that, if leaked, could harm an individual’s privacy, finances, or security.

Examples of SPDI in Cyber Security

  • Passwords and authentication details.
  • Biometric information like fingerprints or iris scans.
  • Financial information such as bank account numbers or credit card details.
  • Medical records and health data.

Common Confusions

  • PII vs. SPDI: Personally Identifiable Information (PII) includes any data that identifies a person (like name or phone number). SPDI, however, covers a subset of PII that is more sensitive.
  • Data vs. Metadata: Not all data collected qualifies as SPDI. For example, browsing patterns may be personal but not always classified as SPDI.
