Landmark Judgments On Smart Home Devices As Legal Evidence
🔍 Overview: Smart Home Devices as Legal Evidence
Smart home devices can record audio, video, motion data, environmental cues (like temperature), and user interactions. Courts are now dealing with questions such as:
Is the data authentic and unaltered?
Does it violate privacy rights (Article 21 in India)?
Is it collected with or without consent?
Does it require a search warrant?
Is it hearsay, or can it be corroborated?

| Consideration | Judicial Approach |
|---|---|
| Privacy | Courts ensure evidence is collected without violating Article 21 (K.S. Puttaswamy) |
| Authentication | Must follow Section 65B for certification of electronic evidence |
| Consent | Seizure and usage of smart device data often hinges on owner/user consent |
| Metadata Verification | Courts check for time stamps, device logs, and tamper-proof data |

| Chain of Custody | Courts demand uninterrupted digital chain of custody to ensure authenticity |
📌 Conclusion
Smart home devices are becoming a powerful tool in modern litigation—particularly in domestic violence, murder, burglary, and child abuse cases. Courts are beginning to accept their data as evidence, provided it's:
Authenticated properly
Doesn’t violate privacy
Collected lawfully
Verified via metadata and forensic analysis
Indian courts, while cautious, are increasingly aligning with global trends in using AI, IoT, and smart device data in evidence.
