Legal aspects and technical characteristics
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

.
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.
Data
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.

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 assistance
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
