Can Chennai police use facial recognition cameras under Tamil Nadu law?

Use of facial recognition cameras by Chennai police is subject to the Tamil Nadu Rent Control Act 1960 and the privacy principles established by the Supreme Court. The Madras High Court has noted that mass surveillance using facial recognition requires safeguards against arbitrary use in Chennai. The Tamil Nadu Rent Control Act 1960 may require transparency about deployment and purpose limitation for facial recognition in Chennai. The Madras High Court has emphasized that data collected through facial recognition in Chennai must be deleted within a reasonable period. Citizens can seek information about facial recognition deployments through RTI in Chennai. The Tamil Nadu Rent Control Act 1960 provides for audit and oversight of surveillance technology used by Chennai police. Misuse of facial recognition data can be challenged before the Madras High Court.
