- Cyber and Technology Law
With advancing technology, many schools have begun using biometric systems (like fingerprint or iris scans) for attendance, security, and access control. While biometric data offers convenience, it also raises serious privacy concerns, especially when collected from children, who are a vulnerable group requiring special protection under data privacy laws.
Biometric data is considered sensitive personal data under most data protection laws globally, including the Indian Digital Personal Data Protection Act, GDPR (EU), and others.
Because children are minors, additional safeguards apply to protect their rights and privacy.
Schools must obtain explicit, informed consent from parents or legal guardians before collecting biometric data from children.
Consent should be clear, specific, and revocable at any time.
Children themselves should be informed about the collection in an age-appropriate manner.
Biometric data should be collected only for legitimate, necessary purposes (e.g., security, attendance).
Schools should avoid excessive data collection and ensure data is not used for unrelated activities.
Schools are responsible for securely storing biometric data with encryption and limited access.
They must implement measures to prevent unauthorized access, leaks, or misuse.
Retention policies must be clear, and data should be deleted once it is no longer needed.
In India, schools must comply with provisions of the Digital Personal Data Protection Act, 2023, which mandates special protections for sensitive data and children’s data.
Other relevant laws may include the Right to Education Act and guidelines issued by education authorities.
Schools should maintain transparency by informing parents and students about what data is collected, how it is used, who has access, and how long it will be retained.
Regular audits and compliance checks are important to maintain trust.
Biometric data breaches can have long-lasting effects since biometrics cannot be changed like passwords.
There are concerns about surveillance, profiling, and potential misuse of data.
A private school introduces fingerprint scanners for student attendance. Before implementation, the school sends detailed information to parents and obtains written consent. The biometric data is encrypted and stored on secure servers accessible only to a limited number of authorized staff. The school also sets a policy to delete data once the student graduates. Parents retain the right to withdraw consent, and the school complies by providing alternative attendance methods for those students.
