📚 Quick Study Guide: Data Privacy & Ethics in Data Science
- 🛡️ Data Privacy: Refers to the right of individuals to control their personal data, including how it's collected, stored, processed, and shared. Key regulations include GDPR (Europe), CCPA (California), and HIPAA (USA, healthcare).
- ⚖️ Data Ethics: A branch of ethics that evaluates data practices, algorithms, and their impact on individuals and society. It addresses issues like fairness, transparency, accountability, and potential harm.
- 📝 GDPR (General Data Protection Regulation): A comprehensive data protection law emphasizing user rights like the right to access, rectification, erasure ('right to be forgotten'), and data portability. Requires explicit consent for data processing.
- 📜 Informed Consent: Requires individuals to be fully aware of what data is being collected, why it's being collected, how it will be used, and who will have access to it, before they agree to share it.
- 🚫 Anonymization & De-identification: Techniques used to remove or obscure personal identifiers from data to protect individual privacy. Anonymized data cannot be re-identified, while de-identified data might still carry some risk.
- 🤖 Algorithmic Bias: Occurs when an algorithm produces unfair or discriminatory outcomes, often due to biased training data reflecting societal prejudices or flawed data collection methods.
- 🔍 Transparency: In data science, it means making the data collection methods, algorithms, and decision-making processes understandable and explainable to stakeholders.
- 🤝 Accountability: Organizations and individuals are responsible for their data practices and for ensuring ethical and legal compliance, especially when dealing with sensitive personal data.
- 📊 Data Governance: The overall management of the availability, usability, integrity, and security of data in an enterprise. It includes establishing policies and procedures for data handling.
