Cyber Forensics And Admissibility In Law
What is Cyber Forensics?
Cyber Forensics (also called digital forensics) is the process of collecting, analyzing, and presenting digital evidence in a legally acceptable manner. This involves the recovery and investigation of material found in digital devices such as computers, mobile phones, storage media, or networks.
With the rise of cybercrime, cyber forensics has become essential in solving crimes involving hacking, data theft, cyberstalking, fraud, identity theft, and more.
Legal Framework Governing Cyber Forensics in India
Information Technology Act, 2000 (especially Sections 65, 65B, 66, 67)
Indian Evidence Act, 1872 (especially Section 65B relating to electronic records)
Criminal Procedure Code, 1973 (for investigation procedures)
Various Supreme Court and High Court judgments that have shaped how cyber forensic evidence is admitted and evaluated.
Admissibility of Cyber Forensic Evidence
Admissibility depends on several factors:
Whether the electronic evidence is authentic and reliable.
The evidence should be accompanied by a certificate as per Section 65B of the Indian Evidence Act.
Proper chain of custody must be maintained.
Expert testimony should explain the process of extraction and analysis.
Evidence must be collected in accordance with due process and constitutional safeguards.
