The convergence of people, processes, and technology has transformed our digital landscape significantly. AI and ML technologies are driving us forward, simplifying intricate and repetitive tasks to a great extent. This new era holds vast possibilities, but it has also revealed new horizons fraught with persistent and severe threats.

Within this evolving landscape, both organizations and threat actors highly prize personal data. Entities use personal information to enhance user interactions and improve their products. At the same time, malicious actors exploit this data for specific and harmful purposes, such as collecting ransom and disrupting operations.

What is Personal Data?

General Data Protection Regulation (GDPR)

According to the GDPR, personal information encompasses any data pertaining to a natural person who can be directly or indirectly identified. This identification can be established through various means, such as a name:

  • identification number,
  • location data,
  • online identifier,
  • Or specific factors related to the individual’s physical, physiological, genetic, mental, economic, cultural, or social identity.

Furthermore, the GDPR outlines “special categories” that cover sensitive information. These categories are subject to stricter regulations for the collection and processing of these data:

  • race,
  • ethnic origin,
  • religious or philosophical beliefs,
  • political opinions,
  • trade union memberships,
  • biometric and genetic data,
  • health information, as well as data related to sexual preferences, sex life, and/or sexual orientation.

The California Consumer Privacy Act (CCPA)

Moving to the CCPA, personal data is defined as data that can identify, relate to, describe, or reasonably associate with a particular consumer or household. The CCPA extends protections to individuals and households but excludes certain information from the personal information category when publicly available, such as:

  • data sourced from government records,
  • professional licenses,
  • and real estate records.

Digital Personal Data Protection Act (DPDPA)

DPDPA defines personal data as information identifying an individual or connected to that individual. It also specifies processing as automated or semi-automated operations performed on digital personal data, encompassing collection, storage, usage, and sharing.

Classification of Personal Data

1. General Personal Data:

  • Definition: Information that does not disclose specific personal characteristics.
  • Examples: Name, email address, phone number, and date of birth.
  • Sensitivity Level: Lower sensitivity; requires basic protection.

2. Sensitive Personal Data:

  • Definition: Information revealing intimate aspects of identity.
  • Examples: Racial/ethnic origin, political opinions, religious beliefs, health data.
  • Sensitivity Level: Higher sensitivity; requires stringent protection due to potential risks.

Regulatory and Specialized Data Categories

3. PCI (Payment Card Industry) Data:

  • Definition: Information used in payment card transactions.
  • Examples: Card number, expiration date, security code.
  • Regulation: Governed by PCI Data Security Standard (PCI-DSS).

4. NPI (Nonpublic Personal Information):

  • Definition: Financial data collected by institutions.
  • Examples: Account numbers, income, credit history.
  • Regulation: Governed by the Gramm-Leach-Bliley Act (GLBA) to ensure privacy and security.

Specialized Protection Categories

5. PII (Personally Identifiable Information):

  • Definition: Information used to identify an individual.
  • Examples: Name, address, IP address, location data.
  • Regulation: Requires specific protection due to identity theft and fraud risks.

6. PHI (Protected Health Information):

  • Definition: Subset of PII focusing on health-related records.
  • Examples: Medical records, lab reports, hospital bills.
  • Regulation: Governed by the Health Insurance Portability and Accountability Act (HIPAA) within the healthcare sector.

Each classification carries distinct characteristics and varying levels of sensitivity, requiring tailored protection measures and compliance with relevant regulations to ensure privacy and prevent potential misuse or breaches.
