1. Taking into account the state of the art, the cost of implementation and the nature, scope, context and purposes of processing as well as the risks of varying likelihood and severity for rights and freedoms of natural persons posed by the processing, the controller shall, both at the time of the determination of the means for processing and at the time of the processing itself, implement appropriate technical and organisational measures, such as pseudonymisation, which are designed to implement data protection principles, such as data minimisation, in an effective manner and to integrate the necessary safeguards into the processing, in order to meet the requirements of this Regulation and the legal act establishing it, and protect the rights of the data subjects.

2. The controller shall implement appropriate technical and organisational measures ensuring that, by default, only operational personal data which are adequate, relevant and not excessive in relation to the purpose of the processing are processed. That obligation applies to the amount of operational personal data collected, the extent of their processing, the period of their storage and their accessibility. In particular, such measures shall ensure that by default operational personal data are not made accessible without the individual's intervention to an indefinite number of natural persons.
