Recent European Union policy discussions have again highlighted the urgent need for consistent recording and analysis of data relating to trafficking in human beings. This article highlights how the MONTRASEC model for monitoring trafficking in human beings, sexually exploited and missing children can address these long standing concerns. The process by which a workable IT tool with contents based on international legal instruments and definitions concerning the three phenomena has been designed and tested by a range of operational agencies in two separate EU Member States is illustrated. The article also illustrates how the MONTRASEC IT tool provides the capacity for these phenomena to be described, interpreted and analysed in an integrated and multidisciplinary fashion for the first time. Critical questions relating to compliance with both Member State and European data protection and privacy legislation are subsequently addressed. The article concludes with an assessment of the role and function of the National Rapporteur within the European Union highlighting that more substantial action at EU level in this area may be required if the potential afforded by the MONTRASEC model is to be effectively realised.
