Cyber Experts As Witnesses
Who is a Cyber Expert Witness?
A Cyber Expert Witness is a person possessing specialized knowledge, skills, or experience in the field of information technology, computer forensics, cybersecurity, or digital data analysis who provides expert opinion or evidence in legal proceedings involving cybercrimes or digital evidence.
Importance of Cyber Experts in Legal Proceedings
Cybercrime cases often involve technical issues like hacking, data theft, digital forgery, email tracing, IP tracking, etc.
The average judge or jury may lack the technical expertise to understand complex digital evidence.
Cyber experts help interpret digital evidence, validate authenticity, reconstruct digital events, and provide expert opinion.
Their testimony is crucial in proving or disproving allegations related to cyber offences.
Legal Basis for Expert Witness Testimony
Under Section 45 of the Indian Evidence Act, 1872, expert opinions are admissible when the court needs to form an opinion on matters of science, art, or specialized knowledge.
Cyber experts fall under this category of scientific experts.
Courts rely heavily on cyber experts to interpret digital evidence like logs, metadata, emails, software, etc.
