Brazil's Data Agency Halts Facial Recognition in Paraná Public Schools

Brazil's National Data Protection Agency (ANPD) has ordered the immediate suspension of biometric data processing for children and adolescents within the public education system of Paraná. The regulatory move comes as a response to a public civil action filed by the State Prosecutor's Office of Paraná (MPPR) against the state administration and the technology provider, Valid Soluções S.A.

The MPPR alleged that the implementation of facial recognition technology violated the General Data Protection Law (LGPD), specifically citing failures in purpose, transparency, and necessity. According to the State Prosecutor's Office, the specific goals of the biometric data processing were not explicitly stated or communicated to the data subjects. The agency noted that parents were not properly informed that facial biometrics would be utilized to monitor students.

The Regulatory Landscape

This suspension occurs during a period of tightening legal frameworks regarding minors and technology in Brazil. The Digital Statute of the Child and Adolescent (ECA Digital), established by Law No. 15,211/2025, entered into force on March 17, 2026. This legislation provides a modernized legal basis for protecting the rights of children and adolescents in the digital environment, creating a stricter environment for the deployment of surveillance tools in educational settings.

Implications for Data Justice

The decision is viewed as a landmark regulatory precedent for the protection of children's biometric data in Brazil. The case highlights a critical intersection of digital rights and socio-economic vulnerability. Because school attendance is a key eligibility requirement for Bolsa Família—Brazil's largest income transfer program serving over 20 million families—the use of AI for attendance monitoring creates a high-stakes environment. The situation suggests that traditional notions of individual consent may be insufficient when the processing of sensitive biometric data is linked to a family's access to essential welfare benefits.

Next Steps

Observers are now watching how the ANPD will handle the ongoing dispute between the MPPR and the state of Paraná. While the immediate processing of biometric data has been halted, the case is expected to shape future interpretations of the LGPD regarding the "necessity" of biometric surveillance in public services. It remains to be seen if the state will propose alternative, non-biometric methods for attendance verification that satisfy the transparency requirements demanded by the prosecutor's office.
