Smart Devices As Proof
What Are Smart Devices?
Smart devices include gadgets like smartphones, smartwatches, IoT devices, fitness trackers, smart home assistants (Alexa, Google Home), dashcams, CCTV, and others capable of generating digital data related to a person’s activity, location, communication, or behavior.
Why Are Smart Devices Important in Legal Evidence?
Real-time and continuous data (calls, messages, GPS, biometrics).
Multi-modal evidence: audio, video, text, sensor data.
Behavior and movement tracking.
Potentially tamper-proof logs with proper digital security.
Contextual proof for timelines, alibis, motive, identity.
Legal Challenges
Authenticity and Integrity: Can the data be tampered with?
Chain of Custody: Was the device seized and data extracted properly?
Admissibility under Indian Evidence Act and IT Act.
Privacy concerns and lawful access.
Expert testimony for technical explanations.
Relevant Legal Provisions
Indian Evidence Act, 1872
Sections 65A and 65B: Electronic records admissibility with proper certification.
Information Technology Act, 2000
Recognition of digital signatures and electronic documents.
CrPC provisions for search and seizure of electronic devices.
