1. Introduction

Biometric Health Discrimination refers to unfair, arbitrary, or unlawful treatment of an individual because of biometric identifiers, biometric measurements, or health-related information derived from biological characteristics. It can arise when hospitals, employers, insurance companies, governments, or digital-health platforms use biological or biometric data to make decisions that disadvantage individuals.

The concept involves two closely related but legally distinct issues:

Biometric-data discrimination: Unfair treatment based on fingerprints, facial geometry, iris scans, voiceprints, or other biometric identifiers, including exclusion caused by inaccurate biometric authentication.

Health-related biometric discrimination: Unfair treatment based on physiological measurements or inferences about a person's health, such as heart rate, gait, sleep patterns, genetic predisposition, or other biological signals.

For example, a hospital might refuse to register a patient because a fingerprint scanner repeatedly fails. An insurer might use an algorithmic assessment of biological data to deny coverage. An employer might use biometric monitoring to penalize workers whose physiological measurements are interpreted as evidence of illness or reduced productivity.

These examples raise questions of equality, privacy, informed consent, data security, medical confidentiality, accessibility, and accountability.

In India, the constitutional right to privacy recognized in Justice K.S. Puttaswamy (Retd.) v. Union of India provides an important foundation for examining the collection and use of biometric information. In comparative law, the United States' Genetic Information Nondiscrimination Act (GINA), the Illinois Biometric Information Privacy Act (BIPA), and disability-discrimination legislation address different aspects of the problem.

2. Meaning and scope

Biometric health discrimination can occur at several stages of the information lifecycle:

Collection

An institution collects fingerprints, facial scans, iris patterns, or physiological measurements without an adequate legal basis or meaningful consent where consent is required.

Inference and profiling

An algorithm uses biological signals to infer illness, disability, stress, fatigue, or future health risks and creates a profile that may be inaccurate or discriminatory.

Decision-making

A hospital, insurer, employer, or public authority uses the information to deny treatment, increase premiums, reject employment, or restrict access to services.

Disclosure and exclusion

Biometric records are disclosed improperly, repurposed beyond their original purpose, or used in systems that systematically exclude certain individuals.

An important distinction is that not every biometric error constitutes discrimination, and not every adverse decision based on health data is unlawful. Liability depends on the applicable law, the nature of the decision, the data used, the justification offered, and the evidence of harm or unequal treatment.

3. Principal forms of biometric health discrimination

A. Healthcare-access discrimination

Biometric authentication systems may be used for patient identification, hospital registration, insurance verification, or access to public health benefits. If an individual's fingerprints cannot be read reliably, a facial recognition system fails, or the system incorrectly matches a record, the person may be denied or delayed access to care.

The risk is particularly serious when the system has no alternative verification process.

A defensible system should provide manual verification, an accessible alternative authentication method, and a procedure for urgent treatment that does not depend on successful biometric matching.

B. Health-insurance discrimination

Insurers may use health assessments, genetic information, or physiological measurements when evaluating applicants and claims. The legal position depends on the type of insurance, the jurisdiction, the information used, and the statutory restrictions.

Potentially problematic conduct includes:

Denying insurance because of an unsupported inference about future illness.

Treating a genetic predisposition as conclusive proof that a person will develop a disease.

Using inaccurate biometric or health profiles to determine eligibility.

Applying exclusions without a reasonable evidentiary or legal basis.

Genetic information must not be confused with ordinary biometric identifiers. A fingerprint used for identity verification does not ordinarily reveal the same information as a genetic test. Nevertheless, genetic discrimination is relevant to the broader legal framework because it demonstrates how biological information can be used to restrict access to insurance and healthcare.

C. Employment-related health discrimination

Employers may use wearable devices, facial analysis, voice analysis, fatigue detection, or physiological monitoring to assess workers.

Examples of potential abuse include rejecting an applicant because an algorithm infers a medical condition, penalizing a worker for physiological indicators associated with disability, or using health-monitoring information for an undisclosed employment purpose.

In the United States, the Americans with Disabilities Act (ADA) and GINA may apply, depending on the facts. GINA specifically restricts covered employers from making employment decisions based on genetic information. It does not generally prohibit every employment decision based on fingerprints, heart rate, or other non-genetic biometric data.

D. Algorithmic and AI-driven discrimination

AI systems may generate health predictions from facial images, voice characteristics, movement patterns, or wearable-device data. These predictions may be affected by unrepresentative training data, poor calibration, measurement errors, or inappropriate assumptions about the relationship between a biological signal and a person's actual health.

The legal issues include:

Disparate treatment of protected groups.

Discriminatory effects produced by an automated system.

Inaccurate or misleading health predictions.

Lack of human review or a meaningful appeal.

Unlawful disclosure or secondary use of sensitive information.

A technically accurate identity-matching system may still be used for an unlawful purpose. Conversely, an inaccurate system does not automatically establish intentional discrimination; additional evidence and the relevant legal test matter.

4. Legal framework in India

A. Constitutional protections

The Indian Constitution does not contain a single provision expressly titled “biometric health discrimination.” Instead, several constitutional guarantees may become relevant, depending on the circumstances.

Article 14 does not prohibit every distinction. A classification must satisfy the applicable constitutional standards. Article 21 likewise does not automatically invalidate every collection of biometric information; the legal basis, purpose, necessity, proportionality, and safeguards are important.

B. Statutory framework

The relevant laws may include:

Aadhaar Act, 2016: Sections 28–30 contain important protections concerning confidentiality, restrictions on use and disclosure, and the treatment of biometric information as sensitive personal information.

Information Technology Act, 2000: Section 43A and the Sensitive Personal Data or Information Rules, 2011 have historically formed part of India's framework for certain corporate data-security and sensitive-information obligations. Their present applicability must be assessed alongside subsequent legislation and commencement notifications.

Digital Personal Data Protection Act, 2023: Establishes a framework for digital personal-data processing. The Act provides for commencement by government notification, so the applicable provisions and commencement position must be verified for the relevant date.

Rights of Persons with Disabilities Act, 2016: May apply where inaccessible biometric systems or discriminatory practices affect persons with disabilities.

Insurance legislation and applicable IRDAI regulations: May govern unfair exclusions, claims, disclosure obligations, and the treatment of policyholders.

Applicable medical confidentiality and professional standards: May regulate the collection, use, and disclosure of health information in clinical settings.

Section 30 of the Aadhaar Act specifically treats biometric information collected and stored under the Act as sensitive personal information. The Supreme Court's Aadhaar judgment also considered statutory restrictions on the use and disclosure of identity information.

5. Important Indian case laws

Case 1: Justice K.S. Puttaswamy (Retd.) v. Union of India (2017)

Supreme Court of India · (2017) 10 SCC 1

Facts and issue: The case concerned whether privacy is a constitutionally protected fundamental right. The nine-judge Constitution Bench examined the relationship between privacy, dignity, autonomy, and personal liberty.

Judgment: The Court unanimously recognized privacy as a fundamental right protected by the Constitution, particularly under Article 21 and the freedoms guaranteed by Part III.

The judgment established that privacy includes protection for personal information and interests relating to bodily autonomy and individual choice. State interference with privacy must satisfy the applicable constitutional requirements, including legality, a legitimate state purpose, and proportionality.

Relevance to biometric health discrimination:

Biometric information cannot be treated as ordinary administrative data without considering the privacy interests involved.

Collection and use of biological information must be assessed against the purpose and legal basis for processing.

Unnecessary collection, excessive retention, or unauthorized disclosure may raise constitutional concerns.

Biometric systems that affect access to essential services require safeguards appropriate to their risks.

Legal principle: Privacy is a fundamental right, and the use of biometric data by public authorities must be evaluated within the constitutional framework.

This judgment is a foundational authority for biometric privacy, although it does not itself establish a universal prohibition on all forms of biometric health discrimination.

Case 2: K.S. Puttaswamy v. Union of India — Aadhaar judgment (2018)

Supreme Court of India · (2019) 1 SCC 1

Facts: The petitioners challenged the constitutional validity of the Aadhaar framework, including the collection, storage, and use of biometric and demographic information.

Issue: Whether mandatory biometric identification and related data-processing arrangements violated constitutional privacy and other fundamental rights.

Judgment: The Supreme Court upheld the Aadhaar Act's core framework, subject to important limitations and conclusions concerning particular provisions. The Court considered the statutory purpose, safeguards, proportionality, and the distinction between authentication for authorized purposes and broader use of personal information.

The Court also addressed the risk that authentication failures could exclude eligible people from benefits. The judgment did not hold that every instance of exclusion rendered the statutory framework unconstitutional, but the treatment of authentication failures remains important when designing accessible systems.

Relevance:

A failed fingerprint or iris scan should not automatically be equated with fraud or ineligibility.

The purpose for which biometric information is collected must remain within the applicable legal restrictions.

Access to essential public benefits raises concerns where authentication technology creates unjustified exclusion.

Data security, confidentiality, and restrictions on disclosure are central to lawful biometric governance.

Legal principle: A biometric identification framework can be constitutionally permissible, but its legality depends on the governing statute, safeguards, authorized purposes, and the constitutional standards applicable to the challenged measure.

Case 3: United India Insurance Co. Ltd. v. Jai Parkash Tayal (2018)

Delhi High Court · Judgment dated 26 February 2018

Facts: The dispute concerned health-insurance coverage for a person suffering from hypertrophic obstructive cardiomyopathy. The insurer relied on an exclusion relating to genetic disorders.

Issue: Whether a broad exclusion of genetic disorders from health-insurance coverage was legally sustainable.

Judgment: The Delhi High Court held that a blanket exclusion of genetic disorders was unreasonable and discriminatory in the circumstances before it. It connected access to health insurance with the right to health and emphasized that insurance terms should not rest on vague or arbitrary classifications.

The Court considered the dangers of excluding individuals because of genetic predisposition without an adequate evidentiary basis or a sufficiently intelligible distinction.

Relevance to biometric health discrimination:

The reasoning is relevant where an insurer uses biological or health-related information to impose a broad exclusion without a rational and legally defensible basis.

However, there is a crucial procedural qualification: the Supreme Court stayed the operation of the High Court's conclusions in this case in August 2018 while issuing notice on the relevant issues. The High Court's findings therefore should not be presented as an unqualified, finally settled nationwide rule. The subsequent procedural history must be checked before relying on the decision in litigation.

Case 4: Dr. Shanthi Rengarajan v. The Oriental Insurance Company Ltd. (2018)

Madras High Court · W.P. No. 43202 of 2016 · 9 March 2018

Facts: The petitioner had a family health-insurance policy. Her son was diagnosed with familial adenomatous polyposis, a genetic disorder. The insurer rejected claims relating to diagnostic procedures and treatment, relying on a genetic-disorder exclusion.

Issue: Whether the insurer's rejection could withstand judicial scrutiny, particularly in light of Article 14 and the reasoning in Jai Parkash Tayal.

Judgment: The Madras High Court applied the reasoning in Jai Parkash Tayal, rejected the insurer's objection to the writ petition in the circumstances, set aside the challenged rejection orders, and directed payment of the claim.

The judgment emphasized that a broad exclusion based on genetic status could have implications beyond private contract law and could raise questions of fairness, equality, and access to healthcare.

Relevance: This case directly illustrates how biological information can become a basis for exclusion from health-insurance benefits.

It is important to distinguish the case's direct holding from the broader constitutional proposition. The court dealt with a specific insurance dispute and relied on the reasoning in Jai Parkash Tayal, whose relevant conclusions were subsequently stayed by the Supreme Court. Accordingly, the broader genetic-discrimination propositions require careful consideration of later proceedings and applicable regulations.

Case 5: Rosenbach v. Six Flags Entertainment Corp. (2019)

Illinois Supreme Court · 2019 IL 123186

Facts: A theme park collected a minor's fingerprint information for admission to its facilities. The claim alleged noncompliance with Illinois' Biometric Information Privacy Act (BIPA), including its requirements concerning notice and written consent.

Issue: Whether an individual must prove actual consequential injury beyond a statutory violation to qualify as an “aggrieved person” under BIPA.

Judgment: The Illinois Supreme Court held that a person could qualify as aggrieved by a violation of the statute's biometric-protection requirements without proving additional actual harm.

Relevance: The case illustrates the importance of statutory duties relating to biometric collection, consent, and disclosure. It is relevant to healthcare systems that use fingerprints or facial recognition, provided the particular processing falls within BIPA's scope.

The decision does not establish a general right to damages for every biometric-data incident worldwide. Its application depends on Illinois law and the statutory elements of the claim.

Case 6: Cothron v. White Castle System, Inc. (2023)

Illinois Supreme Court · 2023 IL 128004

Facts: Employees alleged that their employer repeatedly scanned their fingerprints for timekeeping without complying with BIPA's requirements.

Issue: Whether repeated biometric scans could generate separate statutory violations.

Judgment: The Illinois Supreme Court held that, under the statutory provisions before it, claims could accrue with each unlawful scan or transmission rather than only at the initial collection.

Relevance: A healthcare employer using biometric attendance systems, or a healthcare provider using biometric access controls, may need to assess whether each collection, disclosure, or other processing event complies with applicable requirements.

The decision is especially important for assessing potential exposure arising from repeated noncompliant processing. It concerns statutory biometric privacy, not a general finding of health discrimination.

Case 7: Mosby v. Ingalls Memorial Hospital (2024)

Illinois Supreme Court · 2024 IL 129081

Issue: How BIPA's healthcare-related exclusion applies to biometric information collected, used, or stored in specified healthcare contexts.

Judgment: The Illinois Supreme Court interpreted the exclusion to cover information captured from a patient in a healthcare setting, as well as information collected, used, or stored for healthcare treatment, payment, or operations as defined by reference to HIPAA, regardless of whether the source was a patient.

The Court clarified that this did not create a blanket exemption for all biometric information handled by the healthcare industry.

Relevance: The case demonstrates why healthcare organizations must identify the purpose and context of biometric processing rather than assume that all biometric data held by a hospital is automatically exempt from biometric-privacy legislation.

It is principally a statutory interpretation case, not a ruling that biometric health discrimination is permissible.

Practical Law

6. United States laws relevant to biometric health discrimination

GINA is especially significant because it expressly addresses discrimination based on genetic information. It restricts covered employers from using such information in hiring, dismissal, promotion, and other employment decisions. It also limits the acquisition and disclosure of genetic information, subject to statutory exceptions.

U.S. Equal Employment Opportunity Commission+1

These statutes must be analyzed separately. A fingerprint is a biometric identifier, genetic test results are genetic information, and a medical diagnosis is health information. They may overlap in a particular system, but they do not automatically receive identical legal treatment.

7. How courts can assess a biometric health discrimination claim

A court or regulator may need to examine the following questions.

Was the data collected lawfully? Identify the data collected, the legal basis, the purpose, and any applicable consent or notice requirements.

Was the data used for a permitted purpose? A biometric identifier collected for patient registration may not lawfully be repurposed for unrelated health profiling or employment decisions.

Was there unequal treatment? Determine whether the person was denied treatment, insurance, employment, or another benefit and whether the decision involved a legally relevant protected characteristic or unlawful data use.

Was the decision evidence-based? Examine whether the health inference was medically reliable, relevant to the decision, and supported by adequate evidence.

Were safeguards available? Consider human review, alternative verification, correction of inaccurate records, accessibility, confidentiality, and appeal mechanisms.

What remedy is authorized? Depending on the law, a claimant may seek a corrected record, reconsideration of a decision, compensation, a regulatory complaint, an injunction, or constitutional relief.

A particularly important distinction is between discrimination, privacy infringement, and negligent system design. One event can involve all three, but the legal elements and remedies may differ.

8. Application to common healthcare scenarios

The following examples illustrate how the principles may apply in practice.

9. Accountability and preventive governance

Healthcare institutions, insurers, employers, and developers should adopt safeguards designed to prevent biometric health discrimination.

A. Data minimization

Collect only the biometric information necessary for a specified and lawful purpose. Do not collect physiological or genetic data simply because technology makes it possible.

B. Purpose limitation

Keep identity verification separate from health-risk assessment, employment evaluation, and insurance underwriting unless the additional processing is independently lawful.

C. Human review

Provide a meaningful review process when automated biometric decisions adversely affect access to treatment, insurance, employment, or public benefits.

D. Accuracy and bias testing

Evaluate error rates across relevant populations and circumstances. A system that performs poorly for some users should not automatically be used as the sole gateway to essential services.

E. Confidentiality and security

Restrict access to biometric records, implement appropriate security controls, and establish retention and deletion procedures consistent with applicable law.

F. Effective grievance mechanisms

Individuals should be able to challenge inaccurate records, request reconsideration of adverse decisions, and obtain explanations appropriate to the legal context.

10. Remedies available in India

The appropriate remedy depends on the institution involved, the nature of the decision, and the law in force.

Constitutional remedies: Articles 32 and 226 may be relevant where the requirements for enforcement of fundamental rights or writ jurisdiction are satisfied.

Insurance remedies: The insured person may use the insurer's grievance process, approach the Insurance Ombudsman where eligible, or pursue appropriate judicial or other proceedings.

Data-protection remedies: The applicable statutory framework, commencement notifications, and complaint procedures must be checked for the date of the alleged violation.

Disability-related remedies: The Rights of Persons with Disabilities Act, 2016, may provide relevant protections where the facts establish discrimination or a failure to meet applicable accessibility obligations.

Contractual remedies: An affected person may challenge an improper refusal of benefits or seek other relief available under the governing contract and law.

Compensation and injunctions: These may be available where the relevant statute or established cause of action authorizes them.

Not every privacy breach automatically creates a right to monetary compensation, and not every discriminatory outcome establishes a constitutional violation. The legal basis and available remedy must be identified separately.

11. Critical analysis

The central challenge in biometric health discrimination is that biological data can be used both to protect individuals and to restrict their opportunities.

Biometric authentication may help prevent identity fraud, while health monitoring may support early diagnosis. However, the same systems can generate inaccurate inferences, reveal sensitive information, or make essential services dependent on technology that does not work equally well for everyone.

Three principles are particularly important.

First, biological information should not be treated as destiny. A genetic predisposition, physiological measurement, or algorithmic risk score does not necessarily establish a person's present health, future illness, or ability to work.

Second, technological accuracy and legal fairness are separate questions. A system may identify a person correctly yet still be used for an unlawful purpose. Conversely, a system that makes errors may cause serious harm even without intentional discrimination.

Third, accountability must follow the decision-making chain. Responsibility may involve the institution collecting the data, the developer supplying the algorithm, the organization using its output, or the authority responsible for oversight. The allocation of liability depends on the applicable legal duties and evidence.

12. Conclusion

Biometric health discrimination is an emerging legal issue at the intersection of privacy, equality, healthcare access, insurance regulation, employment law, and artificial intelligence governance.

In India, Justice K.S. Puttaswamy (Retd.) v. Union of India (2017) and the Aadhaar judgment (2018) establish important constitutional principles concerning privacy and biometric identification. Dr. Shanthi Rengarajan v. The Oriental Insurance Company Ltd. (2018) illustrates the judicial concern raised by health-insurance exclusions based on genetic disorders, although the procedural history of United India Insurance Co. Ltd. v. Jai Parkash Tayal requires caution when relying on its broader propositions. In the United States, GINA and cases interpreting BIPA demonstrate how specific statutory protections can address genetic discrimination and biometric-data practices.

The broader legal objective is to ensure that biometric technology serves legitimate healthcare and identification purposes without becoming a mechanism for arbitrary exclusion, unjustified health profiling, or unequal access to essential services.

Research note: For litigation, verify the latest statutory amendments, regulatory commencement notifications, insurance rules, and subsequent appellate orders. The cited authorities address different legal issues; none should be treated as establishing a universal, standalone prohibition on every form of biometric health discrimination.
