The Schengen Information System (‘SIS’) in the field of border checks and return contains alerts on persons for the purposes of refusing entry and stay on the territory of the Member States or of verifying compliance with a return decision, thereby reinforcing the Union’s migration policy and contributing to a high level of security within the area of freedom, security and justice.

Pursuant to Article 20(2) of Regulation (EU) 2018/1861 and Article 4(1) of Regulation (EU) 2018/1860 of the European Parliament and of the Council2, the categories of data that may be entered in an alert in SIS include photographs, facial images and dactyloscopic data (the latter including fingerprints as well as palm prints). Pursuant to Article 22(1) of Regulation (EU) 2018/1861 and Article 4(2) of Regulation (EU) 2018/1860, such data should be entered into SIS, if available.

Article 32(1) of Regulation (EU) 2018/1861, which also applies to the operation of SIS in the field of return pursuant to Article 19 of Regulation (EU) 2018/1860, stipulates that photographs, facial images and dactyloscopic data entered in an alert in SIS are subject to a quality check in order to ascertain that they meet minimum data quality standards and technical specifications.

It is necessary to lay down implementing measures specifying the minimum data quality standards and technical specifications for entering and storing such data in SIS.

The specifications should only set the level of quality required for entering and storing photographs in SIS to be used to confirm the identity of a person in accordance with Article 33(1) of that Regulation. The level of quality required for entering and storing photographs and facial images in SIS to be used to identify a person pursuant to Article 33(4) should be laid down at a later stage, when the conditions laid down in that Article have been fulfilled.

eu-LISA should, in consultation with the SIS II Advisory Group, develop and document the technical details of the standards and specifications laid down in this Decision, in the SIS Interface Control Document and Detailed Technical Specifications. Member States, the European Union Agency for Law Enforcement Cooperation (‘Europol’) and the European Border and Coast Guard Agency should develop their systems in compliance with the specifications set out in these documents.
