What is the term used for Jacob's testimony regarding the accuracy and integrity of technical log files gathered in an investigation?

• A. Justification
• B. Authentication
• C. Reiteration
• D. Certification

Answer: (B)

Authenticating digital evidence means proving that the data presented as evidence is genuine and has not been altered since it was collected. In this scenario, Jacob’s testimony would focus on whether the technical log files accurately reflect what happened in the system and whether their integrity is preserved. He would discuss how the logs were secured and verified—using methods like cryptographic hashes or checksums, digital signatures, precise time stamps, and a documented chain of custody—to show that the files are authentic and unchanged. This is why authentication is the best fit: it specifically addresses the trustworthiness and origin of the evidence. Other terms don’t fit as well. Certification refers to formal approval or validation against standards, not to proving data integrity in a specific case. Justification is about providing reasoning or explanations, not about proving the evidence’s authenticity. Reiteration means repeating content, which has no bearing on whether the data is authentic.
