    Flow-alerta.cab (2026): Chain of Custody. https://flow-alerta.cab/en/glossar/chain-of-custody. Editorially reviewed on: 09 October 2026.

    How much detail would you like?

    Practical

    Relevant for digital forensics, security incidents, sensitive training data, test protocols and all processes in which origin and unchanged delivery must be verifiable.

    Example scenario: After a security incident, a log export is hashed, backed up, and each transfer to analytics personnel is documented with time and purpose.

    For critical data use unique IDs, hash values, timestamps, roles and handover protocols; separate originals and working copies.

    At a glance

    Like a seamless handover protocol: every step must be traceable so that it remains clear who worked with the material when.

    Why it matters in practice

    Relevant for digital forensics, security incidents, sensitive training data, test protocols and all processes in which origin and unchanged delivery must be verifiable.

    Example scenario: After a security incident, a log export is hashed, backed up, and each transfer to analytics personnel is documented with time and purpose.

    Pitfalls and limits

    • Copy files without hash or identification; do not document transfers; mix original and working copy; do not make subsequent changes to the protocol traceable.

    Origin & history

    Chain of Custody is an established term from forensics and evidence management and has been transferred to digital evidence.

    Use in mid-sized companies

    • For critical data use unique IDs, hash values, timestamps, roles and handover protocols; separate originals and working copies.
