How the BIOP was born

At the end of the 2000s, OIMAP's pioneer States found that thefts of works were being recorded in incompatible national files. A buyer could not know whether the work offered to them had been stolen abroad.

The BIOP database was created in 2009 to provide a single point of consultation. It rests on a common format for describing works, which States, museums and police forces have gradually adopted.

This page tells its story, explains its governance and describes how information is gathered, checked and protected.

Governance of the database

The database is under the responsibility of the Heritage Protection Department, which directs a unit of twelve analysts. A supervisory committee of nine members — magistrates, lawyers, representatives of museums and civil society — checks its operation each year and issues a public report.

The rules of publication, correction and withdrawal are set by a regulation approved by the Assembly. It guarantees the rights of owners, of good-faith buyers and of investigators.

How a record is created

The report arrives through the Desk, through a national focal point or by automated exchange with INTERPOL. An analyst checks the elements, contacts the reporter if need be and looks for a possible duplicate. They complete the description with the available information.

The record is published within twenty-four hours when the file is complete. If elements are missing, it is published in a provisional state flagged as such, and enriched afterwards. Every change is timestamped in a log.

Protecting data and people

The database contains sensitive information: museum addresses, circumstances of thefts, owners' identities. Only the data useful for recognising the work are public. The rest is reserved for higher levels of access and protected by encryption.

Consultations are logged. An operator may request the history of its searches, and an owner may know who has consulted their record in the course of an investigation, within the limits of the law.

The database's projects

Three projects are under way: extending image recognition to three-dimensional objects, interconnection with the databases of twenty more States and the opening of a programmable interface for approved platforms.

They come with reflection on the use of artificial intelligence to help analysts spot duplicates and suspect works, with systematic human review of decisions.

« A good record comes down to one detail: a mark on the back, an old repair. It is that detail that makes it possible to recognise the work. »
