Facial Recognition at Protests: Security versus Civil Liberties

Why in News?

The Delhi Police informed the Supreme Court that facial-recognition systems, AI-enabled cameras, surveillance vehicles, drones and smart spectacles were deployed during the Cockroach Janta Party protest at Jantar Mantar. The incident has renewed concerns over biometric mass surveillance in the absence of a dedicated regulatory framework. 

What is Facial Recognition Technology?

• Facial Recognition Technology (FRT) uses algorithms to extract biometric features from an image and compare them against faces stored in a database. 
• It can assist law-enforcement agencies in:
  • Identifying wanted persons and repeat offenders;
  • Tracing missing persons and unidentified bodies;
  • Securing sensitive installations and large gatherings; and
  • Accelerating investigation and verification.
• The proposed Automated Facial Recognition System (AFRS) of the National Crime Records Bureau seeks to provide police agencies with a searchable facial image database.

Constitutional and Democratic Concerns: 

• Right to Privacy: Biometric identification affects informational privacy protected under Article 21, as recognised in K.S. Puttaswamy v. Union of India.
• Chilling effect: Fear of being identified, profiled or subsequently targeted may discourage citizens from exercising freedom of speech and peaceful assembly under Articles 19(1)(a) and 19(1)(b).
• Indiscriminate capture: Unlike targeted surveillance, real-time FRT initially scans everyone within a camera’s range, including persons unconnected with any offence.
• Equality concerns: Unequal error rates across gender, age and demographic groups may produce false positives, arbitrary questioning and discrimination under Article 14.
• Function creep: Data collected for crowd security could later be used for political profiling or unrelated investigations.
• Private-contractor access: Vendor-managed systems raise questions regarding data ownership, storage, sharing, cybersecurity and accountability.
• Opacity: Citizens may not know the source of watchlists, accuracy thresholds, retention periods or mechanisms for challenging an incorrect match.

Gaps in the Legal Framework: 

India has no dedicated legislation regulating police use of FRT. 

• The Criminal Procedure (Identification) Act, 2022 permits collection of specified measurements from particular categories of persons, but does not clearly authorise indiscriminate scanning of peaceful assemblies.
• The Digital Personal Data Protection Act, 2023 provides general data-protection principles but permits exemptions for certain state and law-enforcement purposes and does not specifically regulate biometric profiling or automated decision-making. 

Under the Puttaswamy doctrine, state surveillance must satisfy:

1. Legality: existence of a valid law
2. Legitimate state objective
3. Necessity: absence of an equally effective, less intrusive alternative
4. Proportionality between the objective and rights restricted; and
5. Procedural safeguards against abuse.

Way Forward: 

• Enact a comprehensive surveillance law covering biometric identification.
• Require prior judicial or independent authorisation for real-time mass identification.
• Restrict watchlists to clearly defined categories and verified databases.
• Mandate human verification before coercive action based on an algorithmic match.
• Conduct independent accuracy, bias and cybersecurity audits.
• Prescribe purpose limitation, minimal collection and time-bound deletion.
• Disclose government-vendor data-processing agreements and fix accountability for breaches.
• Establish notice, grievance-redress and compensation mechanisms.
• Prohibit indiscriminate FRT deployment at peaceful political gatherings until adequate safeguards exist.

FRT may strengthen targeted law enforcement, but converting every protest site into a biometric checkpoint threatens democratic participation. India needs a rights-based framework that permits narrowly tailored surveillance while ensuring that technological efficiency does not displace constitutional liberty.
