Data Protection and PII Overview

Study Notes

Personally Identifiable Information (PII)

PII is any data that can be used to identify a specific individual. Examples include name, address, date of birth, social security number, driver's license number, email address, and financial account information.
PII is often sensitive and its unauthorized disclosure can have severe consequences, including financial loss, identity theft, and reputational damage.

Data Protection Laws

Data protection laws vary by jurisdiction, but generally aim to regulate the collection, use, and storage of PII.
Key principles often include:
- Lawfulness, fairness, and transparency in data processing.
- Limitation of data collection to what is necessary for a specific purpose.
- Accuracy and storage time limitations for data.
- Integrity and confidentiality of data.
Specific legislation includes GDPR (General Data Protection Regulation), CCPA (California Consumer Privacy Act), and other regional or national laws.

Privacy Policies

Privacy policies outline how an organization handles PII collected from individuals.
They should clearly state:
- Information collected and its purpose.
- How the information is used, shared, and protected.
- Individual rights regarding their data (e.g., access, correction, deletion).
- Contact information for inquiries or complaints.

Data Breach Response

A data breach is an incident where unauthorized access or disclosure of PII occurs.
A robust data breach response plan is crucial. It should include:
- Immediate notification of affected individuals and relevant authorities (often legally mandated).
- Investigation into the cause and extent of the breach.
- Implementation of preventative measures to prevent future breaches.
- Providing support to affected individuals (e.g., credit monitoring services).
Timeliness and effectiveness of the response are critical.

Anonymization Techniques

Anonymization methods aim to remove or mask PII from data sets while still allowing for analysis or research use.
Common techniques include:
- Pseudonymization (replacing identifying information with unique identifiers).
- Data aggregation (combining similar data points to hide individual details).
- Data perturbation (adding noise to data values).
The level of privacy protection varies according to specific techniques and datasets used.

PII Security Measures

Implement robust security measures to protect PII from unauthorized access, use, disclosure, alteration, or destruction.
These often involve:
- Access control (permissions, authentication).
- Encryption (transforming data into an unreadable format).
- Data loss prevention (preventing sensitive data from leaving authorized systems).
- Secure storage (physical security for hard copy data and digital measures for electronic data).
- Regular security audits and evaluations.
- Employee training on data security policies and best practices.
Maintaining current security awareness is paramount to preventing data breaches.
