A Development of Blockchain based Model of Criminal Records and Justice Process Integrations in Thailand

Abstract

Blockchain technology has the potential to increase transparency and efficiency by data connection and integrating operations between agencies in the justice process. Relying upon cryptography and immutable distributed data stores, the blockchain provides prevention mechanisms to data evidences from unauthorized alteration after the data were collected in the system, thereby, promoting efficiency and accountability in the inter-agency justice procedures. This research proposes the adoption of blockchain platform for private/consortium organizations. Initially, the first three government agencies that should establish their blockchain peer nodes are the Royal Thai Police, the Office of the Attorney General, and the Office of the Court of Justice. The capturing of upstream evidence and criminal data of the whole justice process under these three agencies should be integrated. The subsequent agencies that should also establish their blockchain peer nodes upon their readiness in human resources and internal information systems are the Department of Corrections and the Department of Probation.

This research presents a design of the system based on multi-layers secure architecture. Several critical success factors have been discussed especially those related to development and deployment, as well as mechanisms to increase the performance of blockchain transaction processing. The document management systems are also proposed for handling large data files along with the use of hashing functions to preserve the data integrity. The importance of establishing the peer facilitator and preparing the blockchain technical personnel are also addressed.
