Designing a Private Distributed Ledger Model for Secure Document Flow in Criminal Proceedings

Abstract

We consider designing a two-layer model of a private distributed ledger to organize electronic document flow in criminal proceedings. We create a model that considers specifics of the criminal process, interaction of the parties during the case, and the main risks. It is proposed to use blockchain technology as a basis for the first layer of the model, limiting the decentralization degree to the participation of a certification authority. The second layer of the model is proposed to be implemented based on a "key list" that ensures the confidentiality of information. The developed model can neutralize the risks of forgery, falsification, and destruction of criminal case materials, which contributes to strengthening the status of the court as an institution.
