Europe’s AI Export: Facial Recognition Technology in Brazilian Schools Raises Privacy Concerns

As Europe grapples with regulating artificial intelligence within its borders, companies based on the continent are increasingly deploying AI-powered systems overseas. A recent investigation reveals how European-made biometric software, specifically facial recognition technology, has become embedded in Brazil’s education sector, sparking debate over privacy, data protection, and the potential consequences for students.

Facial Recognition Roll Call in Paraná State

At Colégio Estadual Professor Loureiro Fernandes, a public high school in Paraná, Brazil, a new method of taking attendance is in place. Teachers leverage a mobile app to scan the classroom, and a facial recognition algorithm identifies students, marking them present or absent. This system, developed by Slovak company Innovatrics and implemented through a partnership with Brazilian firms Celepar and Valid, is designed to process the biometric data of nearly 1 million children daily across more than 1,700 schools in the state.

While intended to streamline administrative tasks and recover instructional time, the system is not without its flaws. Teachers report inaccuracies, with students occasionally being incorrectly marked absent. Students are able to correct these errors, but until rectified, the algorithmic judgment stands. Concerns exist that these inaccuracies could impact students’ eligibility for social welfare programs like Bolsa Família, which require consistent school attendance.

Regulatory Arbitrage and the Export of Surveillance

Privacy advocates are raising concerns about “regulatory arbitrage,” where European companies export surveillance technologies to countries with less stringent data protection regulations than those in the European Union. While comparable uses of facial recognition in schools have been blocked in several European countries due to concerns over GDPR compliance and the inability of children to provide meaningful consent, Brazil’s data protection authority only began issuing sanctions in 2023 and has handed down a limited number of penalties to date.

In April 2025, a legal challenge was filed by public prosecutor Marcos José Porto Soares in Paraná, arguing the system violates Brazilian law. The case is ongoing. Despite the legal challenge, the technology is expanding to other Brazilian states, including Rio de Janeiro and São Paulo, and has even been tested in Portugal.

European Restrictions on Facial Recognition in Schools

Several European nations have taken steps to restrict the use of facial recognition in schools. In 2019, Sweden’s Data Protection Authority fined a school board for piloting a similar facial recognition attendance system, citing disproportionate and excessively intrusive surveillance. A Swedish court ruled that schoolchildren cannot freely consent to such technologies. Similarly, an administrative court in Marseille, France, halted facial recognition access system pilots in 2020, citing legal authority issues, invalid consent, and the availability of less intrusive alternatives.

The European Union’s Artificial Intelligence Act, introduced in 2024, further regulates the use of facial recognition, though it does not explicitly address the export of these technologies. Some members of the European Parliament advocated for a ban on exporting systems deemed unacceptable under the AI Act, but this proposal was ultimately excluded from the final legislation.

Brazil’s Embrace of AI and Digitization of Education

Brazil, under the leadership of Renato Feder, former head of Paraná’s education department, has actively embraced the digitization of its education system. Between 2021 and 2024, Paraná spent over R$153 million (€25 million) on private educational platforms, including Google Classroom, EF Education First, Matific, and Quizizz (now Wayground). The implementation of facial recognition for attendance was framed as a means to improve administrative efficiency and recover instructional time lost to non-teaching tasks.

The state partnered with Celepar and Valid to implement the system, with Innovatrics providing the core facial recognition software. Innovatrics states its solution saves 80% of time on roll call per class and allows parents to instantly check their child’s attendance.

Accuracy and Concerns Over Welfare Impacts

Independent studies have questioned the effectiveness of the system. A 2025 study by researchers at São Paulo State University found the system achieved an average accuracy of 91.1%, below the 95% threshold specified in the government’s contract. Teachers report that the system often takes longer to process attendance than manual methods and that errors remain common. A survey by APP-Sindicato, a Paraná teachers’ union, found that eight out of ten educators consider the system less effective than traditional attendance methods.

Concerns have been raised about the potential impact on access to social welfare programs, as eligibility for Bolsa Família depends on school attendance records now largely generated by the facial recognition system. While no direct link between false absences and welfare payment suspensions has been confirmed, the possibility remains a concern.

Legal Challenges and Future Outlook

The Public Prosecution Office in Paraná filed a civil action in April 2025, alleging violations of Brazil’s General Personal Data Protection Law. The case is ongoing, with a ruling expected in the first half of 2026. Despite the legal challenges, Paraná extended its contract for the facial recognition system through September 2026. Innovatrics has too continued to market its technology internationally, including a pilot program at a school in Portugal that has since been halted and is under investigation by the Portuguese data protection authority.
