What it means
A chain of custody is a record that can be read aloud in court: who had the item, from when to when, and what they did with it. Software keeps that record only if every action is tied to a named person and nothing in the record can be edited after the fact.
What to look for
The questions to ask: Is every action tied to a person, a time and a tool version? Can an item leave the record without a trace? Is the original file ever changed, or only read? Can the record be exported and checked by someone who does not use the software?
How DEVI does it
In DEVI, every action on an item writes a line with the person, the time and the version. Originals are opened read-only and hashed; the hash is checked again on every open. The custody record exports with its own hash list, so a prosecutor or a defense examiner can check it without DEVI.
