“Leveraging innovation to fight trafficking in human beings: A comprehensive analysis of technology tools” is a ground-breaking effort to take stock of the current landscape of technology tools used to combat THB, within and outside the OSCE region, including their source, purpose and audience. We believe this will aid anti-THB stakeholders by helping OSCE participating States to engage with technology strategically and by raising awareness about tools to help their work and inspiring them to pursue future innovation.This publication represents the first time the Office of the OSCE Special Representative and Co-ordinator for Combating Trafficking in Human Beings (OSR-CTHB) has partnered with a private sector initiative to conduct research on a topic related to combating THB. The partnership has benefited both the OSCE and Tech Against Trafficking, which have mutually enjoyed and leveraged their knowledge and expertise in order to multiply their efforts to tackle THB. This collaborative approach should be encouraged and adopted by other organizations, especially in the field of technology to combat human trafficking, where knowledge and expertise is spread across sectors. Trafficking in human beings is a crime with implications that affect all of society, including the public and private sectors, and civil society. In recognition of the expansive impact of trafficking, this publication is intended for use by a wide range of stakeholders including law enforcement, policymakers, public service providers, NGOs, private sector companies, survivors’ communities and the general public. It provides information about different technical solutions which can be used by stakeholders in a variety of situations to combat human trafficking. For example, law enforcement can learn about tech tools that can assist in identifying victims and traffickers. Policymakers can learn about what data aggregation and analysis technologies are used to analyse human trafficking marketplaces and the impact of legislation. Survivors can acquire information about tools to seek support and gain access to services.
