What makes this work challenging
Provenance matters
A screenshot alone may not show when a record was created, what system produced it or whether it was altered. Investigators need documented origin and appropriate methods.
Integrity checks have a defined purpose
Cryptographic hashes can help detect changes to file contents, but they do not prove that the original information was true or lawfully collected.
Every handover needs clarity
Records should identify authorised custodians, transfer times, purpose and storage conditions. Missing handover information can undermine confidence in a record.
Access must be limited
Evidence can contain private, commercially sensitive or legally protected information. Staff should only handle material within their authority and approved procedures.
An audit trail is not a verdict
A chain-of-custody record supports accountability but does not establish guilt, wrongdoing or the legal admissibility of evidence by itself.
Worked example
A fictional case contains 80 digital files. Seventy-eight have matching integrity hashes after authorised transfer, while two need investigation. A 97.5% match rate does not establish that all 78 files are authentic or relevant.
The example uses fictional data and is not a reported industry statistic or professional certification.
Portfolio exercise
Create ten harmless text files with invented content and a fictional custody log recording file IDs, transfer times, authorised roles and integrity-check status. Explain what a matching hash can and cannot prove.
Skills and education
Cybersecurity fundamentals, records management, cryptographic concepts, documentation, privacy and incident response.
| Starting point | Practical preparation |
| Secondary school | English, Mathematics, relevant Science or humanities and evidence-based reasoning |
| ITE or polytechnic | Recognised applied programmes and supervised work |
| University | Specialist study and professional requirements |
| Mid-career | Transferable experience compared with verified vacancies |
Professional boundaries
Do not access another person’s devices or accounts, collect private evidence without authority or claim legal conclusions from a classroom exercise.
