Integrity and Chain of Custody Under Challenge
Readiness training. LEA.Training does not grant any official certificate, licence or authority.
Unit K2 (Proving Electronic Records: Certificates, Presumptions and Witnesses) showed how a record gets in. This unit is about the attack that follows: "It may have been changed." You will learn the four common forms of that attack, how a fair opponent makes each one, and how an honest proponent answers.
Focus: custody gaps, hash mismatches and collision arguments, timestamps, and edited media. This unit is general knowledge. It is not legal advice. Rules of professional conduct differ by country, so check with your own bar or regulator.
Learning objectives
- Explain what integrity means in court, and who must show it.
- Test a chain of custody, and answer a gap in one.
- Deal with a hash mismatch and with a collision argument.
- Question a timestamp without overstating what it shows.
- Respond to the claim that a recording was edited or faked.
