Analysis Of Digital Evidence In Cybercrime
With the rise of digital communication, emails, WhatsApp, Telegram, Signal, and other messaging apps have become crucial sources of evidence in civil and criminal proceedings. Legal systems worldwide treat these communications as electronic records under electronic evidence laws.
Legal Framework in India
Indian Evidence Act, 1872
Section 65A: Admissibility of electronic records.
Section 65B: Certification of electronic records to make them admissible.
Key requirement: The electronic record must be authentic, reliable, and unaltered.
Information Technology Act, 2000
Sections 4, 5, 66, 66C, 66D: Deals with electronic communication, hacking, identity theft, and digital forgery.
Principle:
Emails or messages are considered documents if they can be authenticated.
The sender and recipient can be identified through metadata (IP address, timestamps, message logs).
Key Requirements for Admissibility
Authentication of Sender: Proof that the message came from the claimed source.
Integrity: The message must not be altered.
Certification: Under Section 65B, an official certificate confirming digital integrity.
Relevance: Must be directly connected to the case.
Hearsay Exception: Digital messages may sometimes be treated as hearsay; authentication resolves this.
