Conflict, migration, and disaster separate families, leading to years of uncertainty about the fate of loved ones. Along with National Societies, the ICRC helps people to keep in touch or re-connect during crises, exchange news, reunite families, and clarify the fate of missing persons. Different technologies – ranging from facial recognition, to online tracing, to electronic Red Cross Messages – are being explored to support and speed up these efforts. The ICRC is also pursuing a new approach to address the issue of missing migrants that combines complex systems and statistical methods of data analysis to provide answers about their fate and whereabouts.
