Abstract
Criminal justice systems around the world encounter missing case dockets and digital evidence. Problems are also posed by the mechanisms used to share criminal case data, especially email and paper documents that provide exposure to illegal data alteration.
This chapter describes a blockchain model for sharing criminal case data securely and efficiently with authorized criminal justice system entities. The model is implemented using Hyperledger Fabric and promising results were obtained during the simulation experiments. The model enables entities to access criminal case data in real time, which helps speed up the delivery of justice. Moreover, the model improves collaboration among the various entities, especially when it comes to joint operations and investigations involving law enforcement and prosecutors. The model also stores credible evidence because the underlying data is immutable and cannot be deleted.
