How is electronic evidence authenticated?

How is electronic evidence authenticated?

• A. By showing reliability and origin through methods like digital signatures or metadata and witness testimony.
• B. By the sender's claim alone.
• C. By court order only.
• D. By the original paper record.

Answer: (A)

The key idea is that electronic evidence must be shown to be genuine and untampered, with proof of both reliability and origin. Digital signatures provide a strong link to the source and protect against changes since signing, helping establish that the item comes from who it claims to be and remains unaltered. Metadata reveals when, where, and how a file was created or modified, offering traceable provenance that supports its authenticity. Witness testimony, especially from the custodian or someone familiar with how the item was created and stored, can lay out the process and establish the chain of custody, showing the item’s history from origin to presentation in court. Together, these elements demonstrate that the electronic evidence is what it purports to be. The other ideas fall short because a sender’s claim alone isn’t enough to prove authenticity, a court order isn’t the method by which authenticity is shown, and while the original paper record can be important in some contexts, properly authenticated electronic copies can be admissible when they reliably reflect the original.
