We attribute these requirements to the law itself; the precise wording and how a court applies it govern any given matter. This article is general information to help you understand the landscape — it is not legal advice, and you should read the provision as it stands and take counsel where the stakes warrant it.

How to Preserve Digital Evidence Correctly

Good preservation is mostly discipline, and a few habits go a long way. Wherever possible, work on copies and leave originals untouched. At the moment you collect a file, compute and record a cryptographic hash — that single value becomes your anchor for proving the data never changed. Document the chain of custody from the start: who collected the data, when, from where, and each time it changes hands. Where you need stronger assurance, attach a trustworthy timestamp and certify the hashes in a document anyone can re-check. A purpose-built, fully offline tool such as e-Dex, the Digital Evidence Integrity Suite, does this on your own Windows machine, and an online certificate verifier lets a recipient confirm a certificate independently. Built-in operating-system commands can also compute hashes if you only need the raw value.

How should I preserve digital evidence correctly?
Work on copies rather than originals, compute and record a cryptographic hash at the moment of collection, document who collected it and when, and keep that chain of custody updated as the data changes hands. Adding a trustworthy timestamp and a certificate that captures the hashes makes the integrity story stronger and lets anyone re-verify the data later.

Conclusion

Digital evidence is simply relevant information in digital form — but its value depends entirely on whether you can show it is genuine and unchanged. Get the fundamentals right (hash at collection, document custody, certify the result) and a vague file becomes defensible proof.
