Biometrics and Frauds: Challenges in the Brazilian Financial Market

In the face of increasing financial frauds, particularly targeting elderly individuals, the Brazilian judiciary is redefining validation norms for transactions conducted on behalf of pensioners and retirees. Recent decisions from the Superior Tribunal de Justiça (STJ) emphasize that simple facial biometrics are not sufficient to validate such operations, especially when dealing with vulnerable victims like seniors. This approach responds to a growing problem: according to Febraban data, 39% of Brazilians have already fallen victim to banking scams, a rate that reaches 44% among the elderly. Additionally, TCU audits and complaints at Consumidor.gov.br confirm a significant scale of these frauds in the previdenciary sector, with over 35,000 reports in 2023 regarding unauthorized loans by INSS. Attorney José de Souza Junior highlights that while facial biometrics play an important security role, they cannot replace a thorough analysis of consent and legitimacy in transactions. This aligns with global trends in financial protection, where banks are held objectively responsible for frauds committed against vulnerable clients. The challenge for financial institutions is to implement solutions that offer security without compromising the efficiency and accessibility of the Brazilian banking system.
