For many years, cultural property in general and archaeological artefacts in particular have become currencies for small-scale trafficking to terrorist financing or money laundering means for mafia organizations. The challenge of the NOSE project is to be able to implement a technical solution to protect archaeological objects as well as those involved in the preservation of these properties: from the archaeological excavation team to the museum curator. It is therefore a question of proposing a robust, durable and easily usable solution on an excavation site. In this context, a solution based on inks containing nanometric markers is envisaged. This ink will offer different levels of protection and will be easily usable by end users, i.e. archaeologists, museum curators and Law Enforcement Agencies (LEAs).
