1. Introduction

Deepfake Biomarker Liability is an emerging area of biotechnology law, artificial intelligence law, medical negligence, data protection and cybercrime. It concerns the legal responsibility of individuals, companies, developers, healthcare institutions and digital platforms when artificially generated or manipulated biometric or biological data causes injury, deception, discrimination or financial loss.

A deepfake traditionally refers to synthetic or manipulated audio, video, images or other digital content generated through artificial intelligence. A biomarker is a measurable biological characteristic that can indicate a physiological condition, disease, biological process or response to treatment.

Examples of biomarkers include:

Facial characteristics used for biometric identification.

Voice patterns used for identity or health-related assessment.

Eye movements and pupil responses.

Heart rate and physiological signals.

Gait and movement patterns.

EEG and other neural signals.

AI-generated or manipulated medical imaging and diagnostic indicators.

Deepfake biomarker liability arises when these indicators are fabricated, manipulated, falsely attributed to a person or used to produce misleading medical, legal, employment or commercial conclusions.

Example: An AI system manipulates a person's facial movements and voice patterns to generate a false neurological assessment. A hospital relies on that assessment and denies the person treatment or insurance coverage. Questions arise concerning the liability of the person who created the deepfake, the AI developer, the healthcare provider and potentially the platform distributing the manipulated material.

Importantly, Deepfake Biomarker Liability is not yet a universally recognised independent legal cause of action. It is a developing legal framework derived from established doctrines of negligence, product liability, privacy, fraud, defamation, intellectual property and data protection.

2. Meaning and Scope of Deepfake Biomarker Liability

The concept has five major dimensions.

A. Biometric manipulation liability

This arises when facial recognition, voice recognition, fingerprints, iris patterns or behavioural biometric information is artificially altered to impersonate another person.

B. Medical biomarker manipulation liability

This concerns the fabrication or alteration of diagnostic indicators, including medical images, physiological measurements and AI-generated clinical reports.

C. Algorithmic biomarker liability

An AI system may falsely interpret synthetic biometric information as genuine evidence of a disease, psychological condition or neurological characteristic.

D. Identity and privacy liability

Deepfake technology may reproduce an individual's face, voice or biological identity without consent, causing reputational, emotional or financial harm.

E. Evidentiary liability

Manipulated biomarker evidence may be introduced into criminal proceedings, civil litigation, employment investigations or insurance assessments.

The central legal question is:

Who should bear responsibility when artificially manipulated biometric or biological information causes foreseeable harm?

3. Legal Framework in India

India does not presently have a separate statute titled Deepfake Biomarker Liability. However, several existing laws can apply depending on the nature of the manipulation and resulting injury.

A. Information Technology Act, 2000

The following provisions are particularly relevant:

For example, creating a synthetic voice or facial representation to obtain money by impersonation may attract Section 66D if its statutory ingredients are established.

However, not every deepfake is automatically an offence under these provisions. The prosecution must establish the specific elements of the applicable offence.

B. Digital Personal Data Protection Act, 2023

The Digital Personal Data Protection Act, 2023 provides a framework governing the processing of digital personal data.

Biometric information, facial images, voice recordings and identifiable health-related information may fall within its scope when they constitute personal data.

Important legal issues include:

Lawful processing of personal data.

Consent and its validity.

Accuracy and appropriate handling of personal information.

Security safeguards.

Responsibilities of Data Fiduciaries.

Rights and remedies available to Data Principals under applicable provisions.

Example: A company collects facial images to develop an identity-verification system and subsequently uses those images to create synthetic identities without an appropriate lawful basis. Depending on the processing circumstances, the company may face regulatory consequences under applicable data-protection provisions.

The Act should not be interpreted as creating an unrestricted prohibition on all AI-generated content. Its application depends on whether the information and processing fall within its statutory scope and applicable exemptions.

India Code

C. Constitution of India

Three constitutional provisions are especially important:

Article 14: Protection against arbitrary State action and discriminatory treatment.

Article 19(1)(a): Freedom of speech and expression, subject to constitutional restrictions.

Article 21: Protection of life, personal liberty, dignity and privacy.

Deepfake biomarker disputes may involve a conflict between freedom of expression and the individual's rights to privacy, dignity and personal autonomy.

For example, a journalist may lawfully use satire or parody involving synthetic media, whereas fabricating medical evidence to portray someone as mentally ill may raise substantially different legal questions.

D. Consumer Protection Act, 2019

Consumer law may become relevant when businesses market AI-based diagnostic, biometric or health-assessment services using false or misleading claims.

Potential grounds include:

Misleading advertisements.

Unfair trade practices.

Defective services.

Unfair contractual terms.

Deficiency in service.

A company claiming that its AI biomarker system can reliably diagnose neurological disorders may face liability if its representations are misleading and statutory requirements for consumer liability are satisfied.

E. Bharatiya Nyaya Sanhita, 2023

The BNS may apply where deepfake biomarker manipulation involves criminal conduct, including:

Cheating.

Forgery.

Use of forged electronic records or documents.

Criminal intimidation.

Defamation.

Other applicable offences.

The exact provision depends on the conduct, intention, evidence and statutory ingredients.

4. Important Case Laws

The following judicial decisions provide important principles for analysing deepfake biomarker liability. Some concern deepfakes directly, while others establish related principles of privacy, medical consent, negligence and biometric-data protection.

1. Anil Kapoor v. Simply Life India & Ors. (2023)

Directly relevant to deepfakes

Court: Delhi High Court

Decision: 20 September 2023.

Case: Read the judgment

Facts:

Actor Anil Kapoor approached the Delhi High Court seeking protection against unauthorised commercial use of his name, image, voice, likeness and other personality attributes.

The allegations included AI-generated images, face morphing, deepfake videos and misleading commercial representations.

Legal issue:

Whether an individual's personality attributes can be protected against unauthorised AI-generated manipulation and commercial exploitation.

Decision and principles:

The Court granted an interim injunction protecting the plaintiff's personality rights and privacy.

It recognised that unauthorised exploitation of a person's name, image, voice and likeness through AI and deepfake technology may violate legally protected interests.

Relevance to biomarker liability:

This judgment is important because biometric identity is closely connected with a person's face, voice and recognisable characteristics.

If an AI developer or another individual manipulates these characteristics to create false biometric representations, the affected person may seek appropriate injunctive relief and other remedies where the legal requirements are satisfied.

2. Anil Kapoor v. Simply Life India & Ors. (2024)

Court: Delhi High Court

Decision: 30 April 2024.

Case: Read the judgment

Facts:

The proceedings concerned unauthorised exploitation of Anil Kapoor's personality attributes, including his name, image, voice and likeness.

The Court considered the consequences of the defendants' failure to contest certain claims.

Decision:

The Court granted permanent injunctive relief against the defendants concerned in relation to the unauthorised exploitation of the plaintiff's personality attributes.

Legal significance:

The decision strengthens the protection of personality rights against AI-enabled misuse.

In biomarker disputes, it provides a useful basis for considering remedies where fabricated facial or vocal representations falsely suggest a person's participation, endorsement or identity.

It should not, however, be treated as a ruling establishing automatic liability for every AI developer or biometric technology provider.

3. Justice K.S. Puttaswamy (Retd.) v. Union of India (2017)

Constitutional foundation

Court: Supreme Court of India

Citation: (2017) 10 SCC 1.

Facts:

The case concerned the constitutional status of privacy, including the implications of the Aadhaar identification framework.

Legal issue:

Whether privacy is protected as a fundamental right under the Constitution.

Decision:

The Supreme Court unanimously recognised privacy as a fundamental right protected under Article 21 and other freedoms guaranteed by Part III of the Constitution.

Relevance:

Biometric data can reveal intimate aspects of personal identity. Unauthorised collection, manipulation or use of such information may therefore raise serious privacy concerns.

The judgment supplies a constitutional foundation for challenging disproportionate State interference and supports privacy-based arguments in appropriate cases involving private entities through applicable statutory and other legal routes.

4. Shreya Singhal v. Union of India (2015)

Court: Supreme Court of India

Citation: (2015) 5 SCC 1.

Facts:

The case challenged provisions of the Information Technology Act, particularly Section 66A, and examined intermediary liability under Section 79.

Legal issue:

The constitutional limits of online speech regulation and the conditions governing intermediary safe-harbour protection.

Decision:

The Supreme Court struck down Section 66A as unconstitutional and interpreted the intermediary takedown framework in relation to legally recognised grounds and appropriate legal directions.

Relevance:

Social media platforms and hosting services may distribute deepfake biometric material.

The case is relevant when determining the balance between freedom of expression, lawful takedown requirements and intermediary responsibility.

A platform does not automatically become liable merely because manipulated material is uploaded by a user. The applicable statutory conditions and intermediary obligations must be examined.

5. Samira Kohli v. Dr. Prabha Manchanda (2008)

Court: Supreme Court of India

Citation: (2008) 2 SCC 1.

Case: Read the judgment

Facts:

The patient underwent a medical procedure beyond the scope of the consent she had given.

Legal issue:

Whether medical professionals can undertake treatment without obtaining valid and informed consent.

Decision:

The Supreme Court explained that valid medical consent must be voluntary and based on adequate information concerning the proposed treatment.

Relevance to deepfake biomarker liability:

Suppose a healthcare institution uses a patient's facial, vocal or neural data to train an AI diagnostic model or conduct an additional biometric assessment.

If the processing or medical intervention requires consent, the institution must comply with the applicable consent requirements.

Artificially generated medical information cannot be treated as genuine patient consent.

6. Jacob Mathew v. State of Punjab (2005)

Court: Supreme Court of India

Citation: (2005) 6 SCC 1.

Case: Read the judgment

Facts:

The case concerned allegations of medical negligence following a patient's death.

Legal issue:

What standard should apply when determining criminal negligence by medical professionals?

Decision:

The Supreme Court explained the distinction between civil and criminal medical negligence and emphasised that criminal negligence requires a sufficiently high degree of negligence.

Relevance:

Consider a hospital that relies exclusively on a manipulated AI-generated biomarker report and consequently administers inappropriate treatment.

The responsible medical professionals may face civil negligence claims if the applicable duty, breach, causation and damage are established.

Criminal liability requires the additional statutory and evidentiary requirements; an adverse medical outcome alone does not establish criminal negligence.

7. R. Rajagopal v. State of Tamil Nadu (1994)

Court: Supreme Court of India

Citation: (1994) 6 SCC 632.

Case: Read the judgment

Facts:

The dispute involved publication of an individual's life story and the conflict between freedom of the press and privacy.

Legal issue:

Whether publication of private information without consent could violate an individual's right to privacy.

Decision:

The Court recognised the right to privacy and discussed circumstances in which unauthorised publication could result in liability.

Relevance:

Deepfake biomarker technology can expose or fabricate highly personal information concerning an individual's health, identity and biological characteristics.

This judgment supports privacy-based arguments against unauthorised disclosure and exploitation, subject to the applicable legal exceptions.

8. Patel v. Facebook, Inc. (2019)

Court: United States Court of Appeals for the Ninth Circuit.

Case: Read the judgment

Facts:

Facebook users alleged that its facial-recognition system created and stored face templates without complying with the Illinois Biometric Information Privacy Act (BIPA).

Legal issue:

Whether unauthorised collection and processing of facial biometric information could constitute a sufficiently concrete injury.

Decision:

The Ninth Circuit held that the alleged invasion of biometric privacy interests was sufficient to establish standing for the claims before it.

Relevance:

This is an important comparative authority for deepfake biomarker liability.

It demonstrates that biometric privacy violations can be legally significant even without proof of conventional financial loss.

The decision is particularly useful when considering liability for AI companies collecting facial templates, voiceprints or other biometric identifiers without satisfying applicable legal requirements.

It interprets American law and does not independently create a cause of action in India.

5. Who Can Be Held Liable?

Deepfake biomarker liability involves several potentially responsible parties.

Liability is not automatically shared among all these parties. Each defendant's conduct, legal duty, knowledge, causation and applicable statutory protection must be examined independently.

6. Major Legal Doctrines Governing Liability

A. Negligence Doctrine

Negligence is one of the principal foundations of biomarker-related liability.

A claimant generally needs to establish:

The defendant owed a legally recognised duty of care.

The defendant breached that duty.

The breach caused the claimant's injury.

The injury resulted in legally recognised damage.

Example: A laboratory fails to authenticate a patient's biometric sample and reports AI-generated synthetic data as genuine. A doctor relies on that report and administers harmful treatment.

The laboratory may face liability if the required elements of negligence are proved.

B. Product Liability Doctrine

AI-based biometric diagnostic systems may qualify as products or services depending on the applicable statutory framework.

Potential grounds include:

Defective software design.

Inadequate warnings.

Unreliable diagnostic outputs.

Failure to validate training datasets.

Inadequate cybersecurity protection.

Misrepresentation of diagnostic accuracy.

Under the Consumer Protection Act, 2019, product liability provisions may become relevant where the statutory definition and requirements are satisfied.

C. Informed Consent Doctrine

Biometric and biological data can be extremely personal.

Healthcare providers and technology companies must distinguish between:

Consent to medical treatment.

Consent to biometric identification.

Consent to processing health information.

Consent to AI training.

Consent to commercial exploitation.

Consent for one purpose should not automatically be treated as permission for every unrelated purpose.

D. Strict and Vicarious Liability

Depending on the facts, liability may arise without proving direct personal involvement in every wrongful act.

For example:

An employer may be liable for certain acts of employees committed in the course of employment.

A company may be responsible for acts attributable to it under applicable law.

Statutory product liability may impose responsibility on qualifying manufacturers, sellers or service providers.

However, there is no universal rule imposing strict liability on every developer of deepfake technology.

E. Evidentiary Integrity Doctrine

Biomarker evidence must be authenticated before it is relied upon in judicial or administrative proceedings.

Important questions include:

Who generated the biometric information?

Was the original data altered?

Was the sample genuinely associated with the person?

What algorithm processed the information?

Was the model independently validated?

Is there a reliable audit trail?

Can the opposing party examine the methodology?

The Bharatiya Sakshya Adhiniyam, 2023, including its provisions concerning electronic and digital records, may become relevant when manipulated biomarker evidence is presented in court.

4. Neural biomarker manipulation

Fabricating or altering EEG or other neural measurements to misrepresent cognitive or neurological conditions.

8. Corporate and Institutional Accountability

Companies developing biometric AI systems should establish a compliance framework that addresses the complete lifecycle of biometric information.

Essential safeguards include:

Data provenance: Maintain records identifying the original source of biometric information.

Dataset verification: Detect synthetic or manipulated training material.

Model validation: Independently test the accuracy and reliability of AI outputs.

Human oversight: Require qualified human review in high-impact medical and employment decisions.

Audit trails: Maintain records of data alterations and model-generated conclusions.

Incident reporting: Establish procedures for reporting serious data breaches and manipulated evidence.

Consent management: Document the purposes and legal basis of data processing.

Redress mechanisms: Provide a process for correcting false biometric records.

Failure to establish appropriate safeguards may become relevant when determining negligence, regulatory non-compliance or other statutory liability.

9. Remedies Available to Victims

A person affected by deepfake biomarker manipulation may pursue different remedies depending on the circumstances.

A victim may also seek preservation of digital evidence, disclosure of relevant records and removal of unlawful material through appropriate legal procedures.

10. Major Challenges in Determining Liability

Deepfake biomarker disputes create several difficult legal questions.

1. Attribution problem: Identifying the actual creator of synthetic biometric information can be difficult.

2. Causation problem: It may be difficult to establish whether the injury resulted from the deepfake, an AI model's error or an independent human decision.

3. Algorithmic opacity: Companies may refuse to disclose proprietary algorithms or training information.

4. Cross-border jurisdiction: The creator, platform, victim and AI service provider may operate in different countries.

5. Scientific reliability: Courts must distinguish scientifically validated biomarkers from experimental or manipulated measurements.

6. Shared responsibility: Multiple organisations may participate in collecting, processing, generating and distributing biometric information.

7. Freedom of expression: Regulation must distinguish harmful impersonation and fraud from legitimate satire, artistic expression, research and journalism.

11. Hypothetical Case Study

Consider the following situation:

A biotechnology company develops an AI-powered neurological assessment platform. A third party manipulates a patient's facial expressions and EEG recordings to produce a synthetic biomarker report suggesting a serious neurological disorder.

The hospital relies on the report and refuses the patient's employment fitness certificate. The patient subsequently loses employment opportunities.

The following legal issues arise:

The patient could seek correction of the false medical record, appropriate compensation, an injunction and other available remedies.

The decisive issues would include authenticity of the original EEG data, algorithmic reliability, medical causation and the conduct of each defendant.

12. Future Development of Deepfake Biomarker Liability

Future legislation and judicial developments may address the following areas:

Specific legal recognition of synthetic biometric identity fraud.

Mandatory authentication of AI-generated medical evidence.

Certification requirements for AI-based diagnostic systems.

Legal standards for synthetic neurological and genetic data.

Mandatory disclosure of AI-generated medical assessments.

Liability rules for automated medical decision-making.

International cooperation concerning cross-border biometric fraud.

Special protection for children's biometric and biological information.

Independent auditing of high-risk biometric AI systems.

An important future development would be establishing a clear distinction between genuine biological evidence and artificially generated biological representations.

13. Conclusion

Deepfake Biomarker Liability represents an important emerging intersection of biotechnology, artificial intelligence, privacy, medical negligence and cybercrime law.

The Indian legal framework already provides several possible routes for addressing these disputes through the Information Technology Act, 2000, the Digital Personal Data Protection Act, 2023, the Consumer Protection Act, 2019, constitutional privacy principles and general civil and criminal law.

The judgments in Anil Kapoor v. Simply Life India, K.S. Puttaswamy v. Union of India, Samira Kohli v. Dr. Prabha Manchanda and Jacob Mathew v. State of Punjab provide important foundations for analysing identity protection, privacy, consent and professional negligence.

Comparative decisions such as Patel v. Facebook demonstrate the growing legal significance of biometric privacy.

The central principle is that artificial intelligence should not become a means of manufacturing false biological evidence, destroying personal identity or escaping legal responsibility for foreseeable harm.

14. Important Case Law Reference List

Research qualification: These decisions establish related legal principles; none of the Indian Supreme Court decisions listed above directly recognises a standalone cause of action called Deepfake Biomarker Liability.
