Personal identification in the modern world is a priority task, the solution of which is to create enhanced measures for the protection of confidential data and provide controlled access to personal information. The European Parliament decided to create a unified database (DB) intended for the work of law enforcement agencies, border and migration services of the EU. The newly created database is called the Common Identity Repository (CIR) and will allow you to concentrate in a single system the biometric data of citizens living in the EU and in some neighboring states. The CIR will contain the basic information data of citizens, such as: names, dates of birth, passport numbers, as well as biometric data (fingerprints, face scan data). When contacting a single database of border guards or law enforcement officers, the process of unambiguous identification of individuals will be greatly simplified, since previously such data was in different databases and required the coordinated work of departments. The existing Schengen Information System, Eurodac, Visa Information System (VIS) and three new systems will be included in the integrated CIR database: the European Criminal Dossier System for Persons from Third Countries (ECRIS-TCN), the Entry / Exit System (EES) and automatic system of authorization of entry into the Schengen zone (ETIAS). Thus, after the start of CIR, there will already be three largest biometric databases with civilian data in the world. In addition to CIR, these are already working databases of the Chinese government and the Aadhar biometric system in India. At the same time, the EU announced unprecedented measures to protect information from unauthorized entry or computer hacking.
