Proposta de sistema para controle e armazenamento de identidades civis por meio de blockchain e contratos inteligentes

Abstract

The advances observed in the last decades in the Digital Society, driven by high connectivity and rapid exchange of information, have allowed the implementation of new functions, the generation and processing of an unprecedented volume of digital information. This phenomenon has brought convenience, productivity and several benefits to society as a whole. However, in the context of public administration, some privacy, security and reliability challenges become especially relevant when considering the impact of vulnerabilities in these situations. It must be understood that today’s systems, aimed at public agencies, are generally obsolete and easy targets for malicious invaders, in addition to many activities using physical materials, demanding more time and more bureaucracy to complete the tasks. In this scenario, seeking efficient alternatives so that information is handled in a transparent and secure way is a research and development effort, sufficiently necessary and timely. In this work, the aim is to demonstrate an application built with Blockchain and Web3 technologies, responsible for bringing the principles of information security (authenticity, availability, integrity and confidentiality) together with the agility of the processes of creation and management of data, in this context, the administration of civil identities in public bodies, more precisely with the civil police. It is worth mentioning that the system covers other important technologies for data storage and manipulation, among them, we can mention: the Piñata Cloud as a gateway to the IPFS file system, in addition to the use of Ganache to simulate a local network of the Ethereum Blockchain . The objective of the work is to show an application in practice with the idea of merging decentralized technologies with public administration, in this way, it is expected to streamline the internal processes of public management and improve essential requirements that involve public data, such as security, integrity and authenticity of the data.
