π What is Personal Data?
Personal data refers to any information that relates to an identified or identifiable natural person ('data subject'). An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.
π Historical Context and Background
The concept of personal data protection has evolved over decades, driven by increasing concerns about privacy in the face of technological advancements. Early data protection laws focused on specific sectors, but the rise of the internet and globalization necessitated broader, more comprehensive regulations. Landmark legislation such as the EU's General Data Protection Regulation (GDPR) has set a global standard for how personal data is handled.
π Key Principles of Personal Data Processing
- βοΈ Lawfulness, Fairness, and Transparency: Data must be processed lawfully, fairly, and in a transparent manner in relation to the data subject.
- π― Purpose Limitation: Data should be collected for specified, explicit, and legitimate purposes and not further processed in a manner that is incompatible with those purposes.
- β
Data Minimization: Data should be adequate, relevant, and limited to what is necessary in relation to the purposes for which they are processed.
- βοΈ Accuracy: Data should be accurate and, where necessary, kept up to date.
- β³ Storage Limitation: Data should be kept in a form which permits identification of data subjects for no longer than is necessary for the purposes for which the personal data are processed.
- π‘οΈ Integrity and Confidentiality: Data should be processed in a manner that ensures appropriate security of the personal data, including protection against unauthorized or unlawful processing and against accidental loss, destruction, or damage.
- accountability: The controller shall be responsible for, and be able to demonstrate compliance with, the principles.
