File handover log builderfor files you receive and pass on

Why this came up in November 2026

Questions about trusting digital files are reaching courts and the people who advise them. Demand for this topic is smaller than for creators’ topics, and this page says so. Counts below were read on 13 November 2026 (Australia/Brisbane) unless the text says another date. An X post by @Udntnonutn from 15 October 2026 about representatives of OpenAI and Meta warning federal judges about convincing AI-generated video had 2,036 impressions and 111 likes on 12 November. A post by @Mr_jay_pee the same day, predicting that video evidence in court will not be enough once anyone can claim it is AI-generated, had 6,379 impressions and 34 likes. A post by @htTweets on 25 October 2026 about a man reported to have used an AI-generated image to fake a death in court had 3,895 impressions. These are demand signals and opinions, not legal findings.

The tool fills a practical gap for lawyers and paralegals: a plain log of fingerprints, names and dates that anyone can read, and a quick way to check a file against it. It makes no claim about what a court will accept. For records on a deepfake dispute, see the deepfake evidence authentication record checklist.

If the log is something you may need to show later

After you build the log:

1. Save the received files unchanged, and keep working copies separate.
2. Make a TimeBind of each exact file you already hold. The fingerprint is made in your browser and the file stays on your device. You can later download a Proof of Time Certificate.
3. Store the files, the log and the certificate together, with the date you received each file.

A TimeBind shows the exact file existed no later than the recorded time and still matches. The page clock is your own device clock, so a TimeBind gives a time you did not set yourself.

What a TimeBind shows, and what it does not. It shows that an exact file existed no later than a recorded time and that a copy shown later still matches its fingerprint. It does not show who made the file, who owns it, that its contents are true, or whether AI was used to make or edit it. This is general information, not legal advice.
