Cyber Intercept Evidence
Cyber Intercept Evidence: Overview
Cyber intercept evidence refers to information or data obtained by law enforcement or investigative agencies through the interception of electronic communications such as emails, chats, social media messages, internet traffic, or metadata during the course of an investigation.
In the digital age, cyber intercept evidence is vital for investigating cybercrimes, terrorism, fraud, and other offenses where electronic communication forms a key part of criminal activity.
Key Features:
Includes intercepted emails, messages, IP logs, call data records, live monitoring.
Obtained through lawful interception (under legal authority) or sometimes covert operations.
Often requires technical expertise to capture, decrypt, and analyze.
Raises concerns about privacy, legality of interception, admissibility, and chain of custody.
Legal Framework in India:
Section 5(2) of the Indian Telegraph Act, 1885 and Rules 2007 permit lawful interception of messages under certain conditions.
Section 69 of the Information Technology Act, 2000 empowers government agencies to intercept, monitor or decrypt information.
The Indian Evidence Act, 1872 governs admissibility of electronic evidence, including intercepted data.
Courts balance the need for investigation with fundamental rights to privacy (Article 21).
