Marking of data
Article 18
1. For the purposes laid down in Article 1(1), the Member State of origin which granted international protection to an applicant for international protection whose data were previously recorded in the Central System pursuant to Article 11 shall mark the relevant data in conformity with the requirements for electronic communication with the Central System established by the Agency. That mark shall be stored in the Central System in accordance with Article 12 for the purpose of transmission under Article 9(5). The Central System shall inform all Member States of origin of the marking of data by another Member State of origin having produced a hit with data which they transmitted relating to persons referred to in Article 9(1) or 14(1). Those Member States of origin shall also mark the corresponding data sets. 2. The data of beneficiaries of international protection stored in the Central System and marked pursuant to paragraph 1 of this Article shall be made available for comparison for the purposes laid down in Article 1(2) for a period of three years after the date on which the data subject was granted international protection. Where there is a hit, the Central System shall transmit the data referred to in Article 11(a) to (k) for all the data sets corresponding to the hit. The Central System shall not transmit the mark referred to in paragraph 1 of this Article. Upon the expiry of the period of three years, the Central System shall automatically block such data from being transmitted in the event of a request for comparison for the purposes laid down in Article 1(2), whilst leaving those data available for comparison for the purposes laid down in Article 1(1) until the point of their erasure. Blocked data shall not be transmitted, and the Central System shall return a negative result to the requesting Member State in the event of a hit. 3. The Member State of origin shall unmark or unblock data concerning a third-country national or stateless person whose data were previously marked or blocked in accordance with paragraphs 1 or 2 of this Article if his or her status is revoked or ended or the renewal of his or her status is refused under Articles 14 or 19 of Directive 2011/95/EU.
