Digital Timestamp Generator allows you to irrefutably prove the existence of a file at a certain point in time. The app generates independently verifiable and impossible-to-forge electronic timestamps using the free public timestamping service offered by GuardTime.
NEW IN THIS RELEASE: Now you can print an Electronic Timestamp Certificate as evidence that a file has been timestamped.
When your file is digitally timestamped by GuardTime, you can prove three things:
1. The timestamped file existed on the date/time indicated in the timestamp.
2. The timestamped file has not been modified since it was timestamped.
3. The timestamp itself has not been forged, back-dated, or manipulated.
This technology is useful for protecting your intellectual property, documenting photos of your possessions for insurance purposes, or creating an audit trail behind any electronic file.
This app uses GuardTime's free public timestamping service to generate timestamps for non-commercial use. The timestamps generated using the app can be verified using any GuardTime compatible timestamping tool, including the official tools at GuardTime.com. More information about how this works is available on the main screen of the app.
