Unaccompanied Minor Refugees: Blockchain-Based Age Assessment Monitoring with Gantt Chart Integration

Generally, unaccompanied asylum-seekers claim to be minors because chronological age influences how their asylum claim will be processed. In case of serious doubt, an age assessment must be conducted. The age assessment procedure is complex, includes a variety of processes, and involves different phases and actors, from medical doctors to law enforcement officers, and must be followed in a mandatory time sequence, otherwise, the basic rights of the child are violated. This paper proposes a novel procedure of age assessment monitoring with the help of a Gantt chart and the Blockchain decentralized structure. Compared with other solutions, the proposed procedure is versatile, as it can be applied in many cases in the context of a refugee asylum procedure and achieve effective and agile scheduling. Experimental results showed stable performance in large-scale request and processing distributed environments (Blockchain), where the data synchronization speed of the age assessment decision reached four times faster than a traditional procedure, achieving faster data consistency and better protection of unaccompanied children in accordance with the provisions of European and international legislation. Performance evaluation testing validated the procedure’s GUI functionality and the implementation technique robustness.
