"AI Facial Recognition at Protests Raises Privacy and Proportionality Concerns"
Facial Recognition Technology (FRT)
biometric system converting facial geometry into a digital template for database comparison and identity matching.
Chilling Effect
surveillance or legal threat that deters people from exercising fundamental rights without formally prohibiting them.
The constitutional right to protest in India rests on two pillars: Article 19(1)(a) (freedom of speech and expression) and Article 19(1)(b) (right to peaceful assembly). These rights are not absolute — Article 19(2) and Article 19(3) permit the state to impose reasonable restrictions in the interests of public order, sovereignty, and morality. The Supreme Court has consistently held that such restrictions must satisfy the triple test of legality, necessity, and proportionality. In Ramlila Maidan Incident v. Home Secretary, Union of India (2012), the Court affirmed that the right to peaceful protest is a fundamental democratic right and that police action to restrict it must follow due procedure.
The right to privacy, recognised as a fundamental right under Article 21 by the Supreme Court's nine-judge bench in Justice K.S. Puttaswamy v. Union of India (2017), adds a second constitutional dimension to state surveillance. The Court held that any restriction on privacy must satisfy the standards of legality (a law must authorise it), legitimate aim (a genuine state interest), and proportionality (the least intrusive means must be used). This framework directly governs the deployment of facial recognition technology (FRT) at public gatherings, where the state's interest in public order must be weighed against citizens' rights to anonymity, assembly, and free expression.
India's data protection architecture has historically been fragmented. The Digital Personal Data Protection Act, 2023 (DPDPA) is the first comprehensive statutory framework for personal data, but it contains broad exemptions for state security and law enforcement that significantly limit its applicability to police surveillance operations.
Facial recognition technology works by analysing a person's facial geometry from an image or video frame, converting it into a unique digital template, and comparing that template against a reference database. A match is flagged when the similarity score crosses a predefined threshold. Delhi Police, in response to an RTI query in 2022, disclosed that it treats a match as 'positive' when the system shows an accuracy rate of 80% — meaning one in five flagged matches could be a false positive. The US National Institute of Standards and Technology (NIST) has documented that many FRT algorithms exhibit differential error rates across demographic groups, raising concerns about systemic bias in policing outcomes.
The surveillance infrastructure deployed at Jantar Mantar includes a Mobile Command and Control Vehicle, live CCTV feeds, and Ikshana — a mobile surveillance van with eight fixed cameras providing a 360-degree view, equipped with face detection, number-plate recognition, and on-the-spot video analytics. …

With reference to the Digital Personal Data Protection Act, 2023, consider the following statements:
1.Facial images linked to identifiable individuals are covered under the definition of personal data.
2.Section 17 of the Act exempts law-enforcement agencies from all data protection obligations without any condition.
3.The Act lays down a specific framework for police use of facial recognition technology, including retention periods and audit requirements.
Which of the statements given above is/are correct?
Consider the following statements regarding the Supreme Court's judgment in Justice K.S. Puttaswamy v. Union of India (2017):
1.The judgment was delivered by a nine-judge constitutional bench.
2.The Court held that the right to privacy is a fundamental right under Article 19 of the Constitution.
3.The judgment laid down that restrictions on privacy must satisfy the tests of legality, legitimate aim, and proportionality.
Which of the statements given above is/are correct?
With reference to facial recognition technology (FRT) used in policing, which of the following concerns has been documented by the US National Institute of Standards and Technology (NIST)?
Assertion (A): Continuous facial recognition surveillance of all participants at a peaceful protest may be constitutionally disproportionate even if it is technically authorised by law.
Reason (R): The Supreme Court in Puttaswamy (2017) held that a law authorising a restriction on privacy is necessary but not sufficient — the restriction must also be the least intrusive means of achieving a legitimate state aim.
Which of the following is correct?
