      Camera-taken (claimed by device): 28 Oct 2026, 08:12 · Server-received: none — nothing uploaded

    Repair evidence (0)

    Demo · kept in this browser only · cleared on refresh or reset

    Photos: JPEG, PNG, WebP or HEIC up to 10 MB. Documents: PDF, JPEG or PNG up to 15 MB. Voice note up to 5 MB (about 3 minutes). The microphone is only requested when you press Record.

    How real evidence would be protected (not built yet)
    • Server assigns UTC upload-receipt time (and capture-session time where captured in-app); kept separate from editable EXIF and device clocks.
    • SHA-256 hash of the original bytes computed server-side on receipt and recorded in the audit log.
    • Original bytes stored privately and immutably (write-once), accessed only through short-lived signed links after server-side per-property authorisation.
    • Annotations saved as new versions linked to the original; the original is never overwritten.
    • Append-only audit events for add, view, annotate, export and deletion requests.
    • Retention, deletion and privacy controls agreed under a UK GDPR review, including tenant access and erasure handling.
    • Exports include a provenance manifest (hashes, server times, uploader, versions). Visible timestamp watermarks go on derivative/export copies only, never on the original.
    • Even then, a server timestamp shows when the file was received — not when the photo or recording was actually taken.

    Immutable-original design notes (future stage)

    • Originals would be stored write-once with a server-computed hash and server-received timestamp; device/camera timestamps are recorded separately as unverified claims.
    • Edits create new versions; the original and every audit entry are never overwritten or deleted outside an approved retention policy.
    • Requires before launch: authenticated accounts, property-level authorisation, server-side audit log, retention schedule and UK GDPR assessment.
    • In this demo the audit list is append-only in the interface only and resets on refresh.
