This work deals with the problem of prison overcrowding in Senegal and the use of electronic bracelets to reduce this overcrowding. Electronic bracelets collect a variety of data such as location, movements, communication data and biometric data. However, data security is a major concern. The aim of the work is to protect this data by using Internet of Things (IoT) and Fog Computing technologies to limit the data collection perimeter, thereby reducing the transfer of massive amounts of data to remote data offices. The architecture implemented aims to collect only the necessary data from remand and correctional office controlled by departmental courts, to comply with data protection laws and to implement security policies to prevent external attacks. This approach aims to guarantee data confidentiality while enabling the use of electronic bracelets to improve the prison situation in Senegal.
