Brazil Enhances National Identity Card Security with Blockchain Technology

In a significant stride toward modernization, Brazil is rolling out a novel national identity card system, fortified by the integration of a blockchain network. This innovative approach is set to bolster the security of data sharing between the Federal Revenue Service and civil identification authorities.

The cornerstone of this system is the shared registry known as b-Cadastros, designed to underpin the operations of the revenue service. This comprehensive platform facilitates searches, issuance, and modifications of the new ID cards and tax registration numbers. Notably, the platform’s development was orchestrated by Serpro, Brazil’s state-owned IT services corporation.

Serpro’s President, Alexandre Amorim, emphasized the pivotal role of the b-Cadastros blockchain platform in fortifying the National Identity Card project. “The use of the b-Cadastros blockchain platform is a major differentiator for the security and reliability of the National Identity Card project,” he stated.

The National Civil Identity Card (ICN) represents an upgraded iteration of Brazil’s traditional paper-based ID cards, and the nationwide issuance commenced in July 2022. The overarching goal of this project is to centralize the nation’s civil identification system and harness the ICN database to authenticate individuals accessing online public services.

The modern plastic card boasts an innovative feature: it empowers users to generate a single digital version of their identity document. This advancement enhances security, as it allows for validation through a printed QR code. In adopting blockchain technology for the ID cards, the Brazilian government anticipates streamlining processes and curbing fraud and illegal activities. Presently, individuals can request identification cards in all of Brazil’s 27 states, which presents challenges in terms of data integrity and security.

Serpro’s Amorim elaborated on the significance of blockchain technology in safeguarding personal data and thwarting fraudulent activities, thus delivering a more secure digital experience for Brazilian citizens.

The states of Rio de Janeiro, Goiás, and Paraná are set to pioneer the blockchain-based version of the national revenue service’s shared registry for the issuance of the new ID cards this week. The remaining states are poised to follow suit over the next six weeks, marking a significant step forward in enhancing the security and efficiency of Brazil’s identity verification and taxation systems.
