43As a preliminary point, it should be noted that the definition of the concept of ‘personal data’ referred to in Article 3, point 1, of Regulation 2018/1725 is essentially identical to that in Article 4, point 1, of the GDPR. In addition, as is apparent from recitals 4 and 5 of Regulation 2018/1725 and from Article 2(3) and Article 98 of the GDPR, the EU legislature intended to establish a regime for the protection of personal data by the Union institutions, bodies, offices and agencies which is equivalent to that of the GDPR in order to ensure uniform and consistent protection of natural persons with regard to the processing of their personal data within the European Union. It is therefore necessary to ensure that Article 3, point 1, of Regulation 2018/1725 and Article 4, point 1, of the GDPR are interpreted in the same way.
