Recital (53)

The protection of the rights and freedoms of natural persons with regard to the processing of personal data requires that appropriate technical and organisational measures are taken, to ensure that the requirements of this Directive are met. The implementation of such measures should not depend solely on economic considerations. In order to be able to demonstrate compliance with this Directive, the controller should adopt internal policies and implement measures which adhere in particular to the principles of data protection by design and data protection by default. Where the controller has carried out a data protection impact assessment pursuant to this Directive, the results should be taken into account when developing those measures and procedures. The measures could consist, inter alia, of the use of pseudonymisation, as early as possible. The use of pseudonymisation for the purposes of this Directive can serve as a tool that could facilitate, in particular, the free flow of personal data within the area of freedom, security and justice.
