Make an evidence record from a computer
If you photographed the property with a camera and the pictures are on this computer, this page makes the same record the phone app makes. Nothing is uploaded — the files are read here, in this browser, and never leave the machine.
Step 1 — the record
Letters, numbers, dot, dash and underscore.
Letters, numbers, dot, dash and underscore.
Not today — the date the evidence should represent.
Step 2 — the photographs
Choose the pictures. You can add more than one at a time.
Step 3 — say what each one shows
| File | Taken | What it shows |
|---|
Step 4 — write the record
Your record is ready
Fingerprint of this record (SHA-256 of spec.json):
Keep a copy of this fingerprint somewhere other than the folder -- email it to
yourself or to your accountant. The check below can only compare the photographs with the
spec.json beside them; this is what shows later that the record itself is the one
made today.
- Save
spec.jsoninto the same folder as the photographs. The record names the files by their filename, so they must sit together and must not be renamed. - Keep that folder. It is the evidence.
- Check it any time with
verify-evidence-pack.html, which re-computes every digest and tells you whether the photographs still match thisspec.json-- and shows its fingerprint, to compare with the copy you kept.
