(34)Authorities, including authorities in third countries, that issue certificates of qualification, service record books and logbooks in accordance with rules that are identical to those of this Directive, are processing personal data. The authorities involved in the implementation and enforcement of this Directive, and, where necessary, international organisations that established those identical rules, should also have access to the database kept by the Commission for the purpose of evaluating this Directive, for statistical purposes, for maintaining safety, for ensuring ease of navigation and in order to facilitate the exchange of information between those authorities. This access should however be subject to adequate level of data protection, specifically in the case of personal data, and, in the case of third countries and international organisations, should also be subject to the principle of reciprocity.
