Brazil has developed a blockchain network to enhance the security of its new national identity card. The network, known as b-Cadastros, will be used by the federal revenue service and civil identification bodies to search, issue, and change the new ID cards and tax registration numbers. The platform was developed by Brazil’s state-owned IT services corporation, the Federal Data Processing Service (Serpro).
According to Alexandre Amorim, President of Serpro, the use of the b-Cadastros blockchain platform is a significant differentiator for the security and reliability of the National Identity Card project. The new identity card, called the National Civil Identity Card (ICN), is an upgraded version of Brazil’s existing paper ID cards and was first issued nationwide in July 2022. The aim of the project is to centralize the country’s civil identification system and use the ICN database to authenticate users accessing public services online.
The new plastic ID card allows users to generate a single digital version of the document, which is considered safer as it can be validated through a printed QR code. With the blockchain-enabled ID, the Brazilian government hopes to centralize processes and reduce fraud and illegal activities. Currently, it is possible for a Brazilian citizen to request an identification card in each of the country’s 27 states, leading to potential misuse and fraud.
Amorim highlighted that blockchain technology plays a crucial role in protecting personal data and preventing fraud, providing a safer digital experience for Brazilian citizens. The blockchain-based version of the national revenue service’s shared registry will be implemented first in the Brazilian states of Rio de Janeiro, Goiás, and Paraná this week, with the remaining states expected to follow within the next six weeks.
The adoption of blockchain technology for the new national identity card demonstrates Brazil’s commitment to leveraging innovative solutions to enhance security and protect citizen data. By integrating blockchain into their identification system, Brazil aims to reduce fraud and ensure the integrity of its identification processes.
Overall, the implementation of the blockchain network in Brazil’s new ID card system is a significant milestone in the country’s digital transformation journey. It demonstrates the potential of blockchain technology in enhancing security and protecting sensitive data, while also streamlining processes and reducing fraudulent activities. With this initiative, Brazilian citizens can expect a safer and more reliable identification system that will help secure their personal information and prevent identity theft.
