Digital Forensics Admissibility Precedents
What is Digital Forensics Admissibility
Digital forensics involves collecting, preserving, analyzing, and presenting digital evidence from electronic devices such as computers, mobile phones, servers, etc. The admissibility of such evidence in courts depends on its authenticity, integrity, relevance, and compliance with legal standards.
Key Legal Principles for Admissibility of Digital Evidence
Authenticity: Evidence must be shown to be what it claims to be.
Integrity: Evidence must be preserved without alteration.
Chain of Custody: Proper documentation of evidence handling.
Compliance with Legal Provisions: For example, Indian Evidence Act Section 65B for electronic records.
Expert Testimony: Explanation by qualified forensic experts.
Relevance and Probative Value: Evidence should help prove a fact in issue.
