Analysis of implementing blockchain technology to the argentinian criminal records information system

Blockchain is an innovative technology that allows a untrusted node network to share transactional data consistently while removing the need of a centralized authority. In this paper we propose a system to store citizen criminal records in a decentralized way by using a permissioned blockchain, taking advantage of some of its characteristics to ensure privacy, security, immutability, and disponibility of stored sensitive data. This system would overcome the current one since it can cryptographically guarantee that data, once stored, had not been modified but by a competent authority. It also improves the delivery of the records to its destination which can be geographically spread throughout the territory.
