Facial Recognition in Schools: The Hidden Cost to Children's Rights

Is your child’s identity safe in their own school?
Facial recognition, is it truly necessary?
In over 1,700 schools across Brazil’s Paraná state, a facial recognition system developed by Slovak company Innovatrics scans nearly one million children daily. Teachers use an app to photograph classrooms, an algorithm matches faces against biometric databases and marks attendance automatically replacing traditional roll calls within seconds.
Similar uses have been blocked in Europe. In 2019, Sweden’s data authority fined a school board for piloting facial recognition attendance, ruling that children cannot meaningfully consent under GDPR. A French court halted comparable projects in Marseille and Nice the same year, citing proportionality and power imbalances. The EU’s 2024 AI Act strictly regulates such systems but does not restrict their export.
The system’s average accuracy of 91.1% falls below the 95% contract threshold. False absences common in practice serious consequences. Brazil’s Bolsa Família welfare program relies on attendance records, where students may be marked incorrectly. Teachers then report the system often which takes longer than manual attendance and is gradually abandoned in many classrooms.
European firms are exporting surveillance tools that regulators at home consider too invasive for children, with no export controls to stop them. While the technology spreads to other states and countries, its promised efficiency remains unproven, and vulnerable students face the real-world consequences of algorithmic errors. Until oversight improves, these systematic mishaps will persist.
