Name two common legal concepts relevant to digital evidence admissibility.

• A. Authentication and chain of custody.
• B. Jurisdiction and double jeopardy.
• C. Privacy impact assessment and risk scoring.
• D. Habeas corpus and subpoena.

Answer: (A)

Authentication and chain of custody are essential for digital evidence to be admissible in court. Authentication means showing the item is what it claims to be—for example, a file, log, or email really originated from the stated source and hasn’t been altered in a way that changes its content. This is supported by metadata, hashes (like SHA-256), digital signatures, or testimony about how the item was created or obtained. Chain of custody records every person who handled the evidence, every location it was stored, and every transfer or access, creating an unbroken trail that proves the evidence remained unchanged from collection to presentation.

These two concepts directly address the reliability and integrity of digital evidence, which courts require before allowing it as proof. Without proper authentication, a court can’t be sure what the item is. Without a solid chain of custody, questions about tampering or unauthorized access can render the evidence inadmissible or prejudicial.

Other options deal with broader or different legal concepts that don’t govern admissibility of digital evidence in the same way. Jurisdiction and double jeopardy relate to rights and procedures rather than proving authenticity or integrity. Privacy impact assessment and risk scoring are risk-management tools, not standards for evidentiary admissibility. Habeas corpus and subpoenas concern rights and orders rather than the specific standards for admitting digital records.
