Overview of GDPR

Explanation of GDPR and its scope

The General Data Protection Regulation (GDPR) is a comprehensive data protection law that came into effect on May 25, 2018, across the European Union (EU) and the European Economic Area (EEA). It replaced the Data Protection Directive and introduced harmonised regulations for the handling of personal data within the EU member states. The GDPR also has extraterritorial reach, applying to organisations outside the EU that process the personal data of EU residents.

The scope of the GDPR is broad, covering all organisations that collect, process, or store personal data of individuals residing in the EU, regardless of the organisation’s location. It applies to both data controllers, who determine the purposes and means of processing, and data processors, who process data on behalf of controllers.

Key principles of GDPR

The GDPR is built on several fundamental principles that govern the processing of personal data:

Lawfulness, fairness, and transparency: Personal data must be processed lawfully, fairly, and in a transparent manner. Organisations must have a valid legal basis for processing personal data and provide clear and understandable information to individuals about how their data will be used.
Purpose limitation and data minimization: Personal data should be collected for specified, explicit, and legitimate purposes and not further processed in a manner incompatible with those purposes. Organisations should only collect and retain the minimum amount of personal data necessary to fulfill their intended purposes.
Consent and user control: Consent for data processing must be freely given, specific, informed, and unambiguous. Individuals have the right to withdraw consent at any time and have control over their personal data, including the right to access, rectify, restrict processing, and erase their data.
Data protection by design and default: Organisations must implement appropriate technical and organisational measures to ensure data protection principles are integrated into the design of their systems and services. Privacy-enhancing measures, such as pseudonymization and encryption, should be implemented by default.
Security and data breach notification: Organisations are required to implement appropriate security measures to protect personal data from unauthorised access, loss, or destruction. In the event of a data breach, organisations must notify the supervisory authority and, in certain cases, affected individuals without undue delay.

Data protection rights of individuals under GDPR

The GDPR grants individuals several rights regarding their personal data:

Right to information: Individuals have the right to be informed about the collection and use of their personal data, including the identity of the data controller, purposes of processing, recipients of the data, and retention periods.
Right of access: Individuals can request access to their personal data held by an organisation and obtain information about how their data is being processed.
Right to rectification: Individuals have the right to have inaccurate or incomplete personal data corrected.
Right to erasure (right to be forgotten): Individuals can request the deletion of their personal data under specific circumstances, such as when the data is no longer necessary for the purposes it was collected or when the individual withdraws consent.
Right to restrict processing: Individuals can request the limitation of processing their personal data, usually while a dispute or inquiry is ongoing.
Right to data portability: Individuals have the right to receive their personal data in a structured, commonly used, and machine-readable format and transmit it to another data controller.
Right to object: Individuals can object to the processing of their personal data, including profiling, for direct marketing or legitimate interests pursued by the data controller.

These rights empower individuals to have more control over their personal data and ensure that organisations handle their information in a responsible and transparent manner.
