The seven main principles of GDPR are:
1. Lawfulness, fairness, and transparency: Personal data must be processed lawfully, fairly, and transparently. This means that data processing must have a legal basis, be conducted in a way that respects individuals' rights, and be clearly communicated to them.
2. Purpose limitation: Personal data should be collected for specified, explicit, and legitimate purposes and not further processed in a manner that is incompatible with those purposes.
3. Data minimization: Only the minimum amount of personal data necessary for the specified purpose should be processed. This principle emphasizes limiting the collection and storage of personal data to what is strictly necessary.
4. Accuracy: Personal data must be accurate and kept up to date. Data controllers are responsible for taking reasonable steps to ensure the accuracy of the data they process and, where necessary, rectify or erase inaccurate or outdated information.
5. Storage limitation: Personal data should be kept in a form that permits identification of data subjects for no longer than is necessary for the purposes for which the data is processed. This principle encourages the deletion or anonymization of data when it is no longer needed.
6. Integrity and confidentiality: Personal data must be processed in a manner that ensures appropriate security, including protection against unauthorized or unlawful processing and accidental loss, destruction, or damage.
7. Accountability: Data controllers are responsible for complying with the principles of GDPR and must be able to demonstrate compliance. This includes implementing appropriate measures, documenting data processing activities, and conducting data protection impact assessments when necessary.
