Purpose limitation: Personal data must be collected for specific, explicit, and legitimate purposes and not further processed in a way that contradicts those purposes. Data minimization: Personal data must be adequate, relevant, and limited to what is necessary for the purposes for which it is processed. Accuracy: Personal data must be accurate and, where necessary, kept up to date. Storage limitation: Personal data must be kept in a form that allows data subjects to be identified for no longer than is required for the purposes for which the personal data is processed. Integrity and confidentiality: Personal data must be securely processed to prevent unauthorized processing, accidental loss, destruction, or damage. Responsibility: Organizations must be held accountable for GDPR principles and be able to demonstrate compliance. Right to be informed: Data subjects have the right to be informed about how their data is collected and used.
