According to Article 14 of the GDPR, where personal data is not obtained directly from the data subject, the controller must provide the data subject with certain information about the processing, such as the identity of the controller, the purposes and legal basis of the processing, the categories of personal data concerned, the recipients or categories of recipients of the personal data, and the rights of the data subject12. However, there are some exceptions to this obligation, as specified in Article 14(5). One of them is when the provision of such information proves impossible or would involve a disproportionate effort, in particular for processing for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes, subject to the conditions and safeguards referred to in Article 89(1) or in so far as the obligation is likely to render impossible or seriously impair the achievement of the objectives of that processing12. In such cases, the controller must take appropriate measures to protect the data subject's rights and freedoms and legitimate interests, including making the information publicly available12.
