1. Meaning of Digital Tracing Consent

Digital tracing consent is the freely given, informed, specific, and unambiguous agreement of a person to allow:

• Location tracking (GPS, mobile signals)
• Contact tracing (health surveillance apps)
• Behavioral tracking (cookies, analytics, AI monitoring)
• Biometric tracking (face recognition, fingerprints)
• Device tracking (IMEI, MAC address, IP logs)

It is widely used in:

• Public health (e.g., pandemics)
• Law enforcement surveillance
• Workplace monitoring
• Digital marketing and social media tracking

2. Legal Requirements for Valid Digital Consent

For consent to be legally valid, most modern privacy regimes require:

(A) Freely Given Consent

• No coercion or pressure
• No “take it or leave it” forced acceptance (in many contexts)

(B) Informed Consent

User must know:

• What data is collected
• Purpose of tracking
• Who will access it
• Retention period
• Risks of sharing data
• Whether data is shared with third parties

(C) Specific Consent

• Separate consent for separate purposes
• No blanket acceptance for multiple unrelated uses

(D) Unambiguous & Affirmative Action

• Tick box / opt-in required
• No pre-ticked boxes (in GDPR jurisdictions)

(E) Revocable Consent

• User must be able to withdraw consent easily

3. Validity Issues in Digital Tracing Consent

Digital consent is often challenged due to:

1. Lack of Real Choice (Coercion)

• “Agree or lose access to service”

2. Hidden or Complex Privacy Policies

• Long unreadable terms

3. Passive Consent

• Pre-ticked boxes
• Implied consent through usage

4. Over-broad Consent

• One consent covers unlimited future uses

5. Data Imbalance

• User lacks understanding of surveillance tech

4. Major Case Laws

1. Justice K.S. Puttaswamy v. Union of India

Court: Supreme Court of India

Key Principle:

The Court recognized privacy as a fundamental right under Article 21.

Relevance to Digital Consent:

• Any digital tracing must satisfy:
  • legality
  • necessity
  • proportionality
  • procedural safeguards
• Consent must be meaningful, not forced or illusory

Impact:

This case became the foundation for all Indian digital privacy and tracing laws, including surveillance and health tracking apps.

2. Carpenter v. United States

Court: Supreme Court of the United States

Facts:

Government obtained mobile location data (CSLI) from telecom providers without a warrant.

Judgment:

• Cell-site location data is protected under the Fourth Amendment.
• Continuous tracking requires judicial authorization.

Principle:

Digital location tracking is highly sensitive and requires strong legal safeguards beyond implied consent.

3. European Union GDPR enforcement framework

Although not a single case, GDPR enforcement decisions are crucial.

Principle under GDPR:

Consent is valid only if:

• Freely given
• Specific
• Informed
• Unambiguous

Key Impact:

• Pre-ticked boxes = invalid consent
• Bundled consent = invalid
• Users must be able to withdraw easily

4. Google Spain v. AEPD and Mario Costeja González

Court: Court of Justice of the European Union

Principle:

• Individuals have the “right to be forgotten”
• Digital data processing must respect personal autonomy

Relevance:

Strengthens the idea that digital tracking and storage require ongoing consent and control.

5. Schrems II

Principle:

• Invalidated EU–US Privacy Shield
• Emphasized strict protection of personal data transfers

Relevance:

• Even cross-border digital tracing requires strong consent + safeguards
• Government access risks must be disclosed

6. India COVID-19 Contact Tracing (Aarogya Setu Context)

While not a single landmark judgment, policy scrutiny around the Aarogya Setu app raised major legal concerns:

Key issues:

• Whether consent was truly voluntary
• Whether users could access services without installing it
• Data retention transparency

Legal criticism:

• “Consent under public health emergency may become de facto compulsory”
• Raises question: Is consent truly voluntary in digital tracing systems?

5. Special Issues in Digital Tracing Consent

(A) Implied vs Explicit Consent

• Traditional law accepted implied consent in limited cases
• Modern digital law strongly prefers explicit opt-in consent

(B) “Consent Fatigue”

Users constantly click “Accept” without reading, making consent legally questionable.

(C) Power Imbalance

Example:

• Employee tracking software
• Employer demands consent as condition of employment

Courts may treat such consent as not freely given.

(D) Continuous Tracking Problem

Unlike one-time consent (like surgery), digital tracing is:

• continuous
• invisible
• automated

This increases legal scrutiny.

6. When Digital Tracing Consent is Valid

Consent is generally valid when:

• User actively opts in
• Purpose is clearly explained
• Data scope is limited
• No penalty for refusal (where feasible)
• User can withdraw anytime
• Transparency is maintained

7. When Digital Tracing Consent is Invalid

Consent is usually invalid when:

• Forced acceptance to access essential services
• Hidden tracking in background apps
• Vague privacy policy
• No real alternative choice
• Overbroad “all-purpose” consent clause

8. Key Legal Principles Summary

Conclusion

Digital tracing consent is legally valid only when it is real, informed, and freely given, not just a formal click. Courts globally—especially in Puttaswamy (India) and Carpenter (USA)—have emphasized that digital surveillance and tracking systems require heightened protection due to their intrusive nature.
