The Principles in Article 5 say that Personal data shall be:
  • processed lawfully, fairly and in a transparent manner in relation to the data subject (‘lawfulness, fairness and transparency‘);
  • collected for specified, explicit and legitimate purposes and not further processed in a manner that is incompatible with those purposes (‘purpose limitation‘);
  • adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed (‘data minimisation‘);
  • accurate and, where necessary, kept up to date; every reasonable step must be taken to ensure that personal data that are inaccurate, having regard to the purposes for which they are processed, are erased or rectified without delay (‘accuracy‘);
  • 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 (‘storage limitation‘);
  • processed in a manner that ensures appropriate security of the personal data, including protection against unauthorised or unlawful processing and against accidental loss, destruction or damage, using appropriate technical or organisational measures (‘integrity and confidentiality‘)

The data controller shall be responsible for, and be able to demonstrate compliance with the principles (‘accountability‘).
