What is Biometric Recognition Technology?

Biometric Recognition Technology is an automated system that utilizes distinctive biological or behavioural characteristics to identify and verify individuals. Examples of biometric recognition methods include:

• Fingerprint Recognition: This technology identifies individuals based on unique patterns in their fingerprints, widely used in mobile devices and security systems.
• Face Recognition: Facial features are used to verify a person’s identity, employed in smartphone unlocking and surveillance systems.
• Iris Scanning: Scanning the patterns in the iris for high-accuracy identification, commonly used in border security and access control.
• Voice Recognition: Analyzing voice characteristics for authentication in applications like voice-activated systems and phone-based verification.

These methods offer enhanced security and convenience but also raise privacy and ethical considerations. Biometrics play a significant role in applications ranging from mobile authentication to law enforcement.

Facial Recognition Technology in India

India currently lacks a dedicated data protection law or specific regulations governing facial recognition technology (FRT). However, the Ministry of Home Affairs has issued guidelines to oversee the use of automated facial recognition systems (AFRS) by law enforcement agencies. The unrestrained deployment of facial recognition systems for potentially unwarranted purposes has ignited privacy concerns, with many individuals unaware of constant surveillance in public spaces. Some notable details on FRT in India include:

• 125 FRT systems are in operation nationwide.
• The government has invested over INR 1,464.18 Cr in these systems.
• FRT is used for entry at three major Indian airports: Delhi, Bengaluru, and Varanasi, with plans for nationwide implementation.
• NEC India claims its FRT algorithms can identify individuals even when their features are obscured by masks.
• Staqu allegedly supplied FRT technology to law enforcement agencies in at least eight states, including Uttar Pradesh.

Features of Biometric Recognition Technology

Biometric recognition technology incorporates several features that make it a valuable tool for identifying and verifying individuals. Some key features include:

• Uniqueness: Biometric traits are inherently unique to each individual, ensuring that no two people have precisely the same biometric features.
• Universality: Most people possess the biometric trait under consideration, such as fingerprints, making it widely applicable.
• Permanence: Biometric traits are relatively stable over time, ensuring consistent recognition over the long term.
• Collectability: The technology can gather biometric data in a convenient and non-invasive manner.
• Performance: Biometric recognition systems should have low error rates in identifying individuals accurately.
• Acceptability: People are generally comfortable with biometric identification, as it’s a natural and convenient way to prove identity.
• Circumvention Resistance: Biometric systems are designed to be resistant to fraudulent attempts to mimic or alter biometric data.

These features make biometric recognition technology suitable for a wide range of applications, from secure access control to personal device authentication and law enforcement.

Biometric Recognition Technology UPSC

Biometric Recognition Technology utilizes unique physical or behavioural traits like fingerprints, faces, irises, and voices for identity verification. While offering enhanced security and convenience, it raises privacy and ethical concerns. In India, there’s no specific data protection law for facial recognition technology, but the Ministry of Home Affairs has issued guidelines.

The unchecked use of facial recognition systems has privacy implications, and India has deployed 125 systems. Other applications include Aadhaar for citizen identification, banking, healthcare, education, and law enforcement. Challenges encompass security vulnerabilities, accuracy issues, cost, and data privacy. The future holds promise with advancements like multimodal biometrics and continuous authentication.
