Existamp’s file-timestamp receipt
Existamp creates a free receipt timestamping a fingerprint of selected files, which can later be checked against the originals.
- For
- Creators and people documenting property or deliveries
- Worth noticing
- The page explicitly says timestamps do not establish authorship, truth, location, or whether a photographed scene was staged.
Field notes
On the device, a user adds files or takes photos, and the set is reduced to one fingerprint before timestamping; the site says only that fingerprint is sent to a free public timestamp service. A downloadable zip holds the receipt for later checking, which can be done by anyone without an account. Existamp distinguishes timestamp evidence from proof of authorship, truth, location, or an unstaged scene, and says a court, deposit scheme, or hire company decides what it accepts.
