Schengen Information System
The Schengen Information System (SIS) is a governmental database maintained by the European Commission. The SIS is used by 31 European countries to find information about individuals and entities for the purposes of national security, border control and law enforcement. A second technical version of this system, SIS II, went live on 9 April 2013.
Information in SIS is shared among the institutions of countries participating in the Schengen Agreement Application Convention (SAAC). The five original participating countries were France, Germany, Belgium, the Netherlands, and Luxembourg. Twenty-one additional countries have joined the system since its creation: Spain, Portugal, Italy, Austria, Greece, Finland, Sweden, Switzerland, Denmark, Iceland, Norway, Estonia, the Czech Republic, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, Slovenia and Liechtenstein. Among the current participants, Iceland, Liechtenstein, Norway, and Switzerland are not members of the European Union.
Although Ireland and the United Kingdom have not signed the Schengen Agreement Application Convention, they take part in Schengen co-operation under the terms of the Treaty of Amsterdam, which introduced the provisions of Schengen acquis into European Union law. Schengen acquis allows the United Kingdom and Ireland to take part in all or part of the Schengen convention arrangements. Ireland and the United Kingdom use the Schengen Information System for law enforcement purposes.
Ireland and the United Kingdom do not have access to Article 26D (former 96) data because these countries do not intend to remove the border controls between themselves and the rest of Europe. European citizens still have the right of free movement to the UK and Ireland but must pass through a border control point, unlike the other Schengen signatory countries, among whom internal border controls have been largely abolished. Since 1 August 2018, Bulgaria and Romania have full access to SIS; before that they had access to SIS only for law enforcement purposes. Croatia has access to SIS for law enforcement purposes, while Cyprus do not have any access.
SIS information is stored according to the legislation of each participating country. There are more than 46 million entries (called "alerts") in SIS, most about lost identity documents. Person alerts make up around 1.9 percent of the database (about 885,000 records). Each alert contains information such as: name, date of birth, gender, nationality, aliases, arms or history of violence, the reason for the alert and the action to be taken if the person is encountered. SIS does not record travellers' entries and exits from the Schengen Area.
On 25 March 1957, the Treaty of Rome was completed. On 3 February 1958, the economic union of the Benelux countries was formed. Both agreements aimed to enable the free movement of people and goods across national borders. The Benelux countries, as a smaller group, were able to quickly implement the agreement. The European Communities' focus was on economic integration. It was not until the agreement of Saarbrücken was completed on 13 July 1984, that border controls between France and Germany were eased.
On 14 June 1985, France, Germany and three of the Benelux nations completed the Schengen Agreement. Border controls on people and goods between these nations were gradually relaxed. On 19 June 1990, the initial five nations were joined by Spain, Portugal, Italy, Greece, Austria and five Nordic Passport Union countries: Denmark, Finland, Iceland, Norway and Sweden.
On 21 December 2007, the Schengen border-free zone was enlarged to include Estonia, the Czech Republic, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia.
Legal aspects and technical characteristicsEdit
SIS was created to maintain European security after 25 March 2001 when border security between fifteen nations was relaxed. The SIS requires Schengen nations to respect the legal force of the information it contains. It also requires the nations to respect the privacy and personal freedom of the people whose data is held according to national data laws. SIS's information processing system must be permanently connected to member nations' databases and must be updated in real-time.
These commitments are supplemented by consultation procedures between the member nations. Discussions may take place about issues such as confirmation of information, variation of actions directed by SIS, questions of residency, and international warrants for arrest.
SIS is controlled by an authority composed of representatives of the member nations. Personal data protection is a key responsibility. At a technical level, the participating countries adopted a data-processing star architecture made up of a central site containing the reference database, known as C-SIS, for which the responsibility is entrusted to the French Republic by the CAAS, and a site by country, known as N-SIS, containing a copy of the database.
The type of data about people kept in SIS includes: requests for extradition; undesirability of presence in particular territory; minor age; mental illnesses; missing person status; a need for protection; requests by a judicial authority; and suspected of crime. The SIS also keeps data referring to lost, stolen and misappropriated firearms, identity documents, motor vehicles and banknotes.
France is responsible for management of SIS and uses an automated system of data updates which occur every five minutes. The SIS automatically directs data to queries arriving via large national databases. Each member nation has an office responsible for SIS communications. SIS also has a function called "Supplementary Information Request at the National Entry" (SIRENE). The SIRENE office records an "hit" on a SIS data record and forwards further information to assist investigations.
Police co-operation and legal mutual assistanceEdit
In addition to SIS and SIRENE, the Schengen convention ensured police co-operation and legal mutual assistance. Police of member nations can cooperate to prevent and identify crime (article 39); to continue surveillance across borders (article 40); to pursue across borders in certain circumstances (article 41); and to share information that is significant for the repression or the prevention of in flagrante delicto or threats to order and public safety (article 46). This allows execution of criminal judgements and extraditions where a national attempts to take refuge in another territory.
In November 2011, SIS1 was renewed for a second time. The main reason for renewal was to connect more nations.
