How is electronic evidence authenticated?

How is electronic evidence authenticated?

• A. The source and integrity must be established, often via testimony or metadata
• B. A notarization on the document suffices
• C. A chain of custody is unnecessary for digital items
• D. The original source automatically authenticates it

Answer: (A)

Authentication of electronic evidence hinges on proving where the item came from and that it has not been altered since it was created or received. The most reliable way to establish this is through testimony from someone with knowledge of the item and by showing metadata or other technical indicators that tie the file to its source and verify its integrity. In practice, courts look for a chain of custody and corroborating evidence such as hashes, timestamps, and logs that demonstrate the item is unchanged and is exactly what it purports to be. Notarization on the document does not by itself prove authenticity of digital content, and a chain of custody is essential for digital items. The original source does not automatically authenticate the item; additional foundation is needed to show it is what it purports to be and that it has not been altered.
