Timestamp certification for creative work

Act now — just three minutes can defuse the long-term “time bomb” hanging over your creative work.

The hard part for a creator is often not a lack of ideas. It is having to prove: I made this first.

We help you keep a timestamp "fingerprint" of your precious original work. Today, generative tools can produce near-identical images in minutes, and social platforms have diluted how rare originality feels. Some things only become easier when you prepare one step ahead, so you stay calmer when trouble actually arrives. When infringement happens, you often still have the source file; what you need is to show its basic metadata was not altered, especially its time. We use current technology to certify that this file already existed at a moment in time.

Stamp nowHow does this work?

Don't wait — many creators regret delaying until it was too late

  • You keep the source file; we only provide timestamp certification
  • Traceable certification
  • Certification submitted to Bitcoin anchor
  • Public operations log
  • Proofs stay usable for life, verifiable anywhere, and do not depend on our servers

Bitcoin block 890124 attests that this fingerprint existed before that height.

The fingerprint is anchored in Bitcoin and written to the operations log.

Recompute SHA-256 on the same file. A matching digest shows the bytes are unchanged. This record shows the file already existed when this certification was issued. "You must provide the source file yourself, and it must be unchanged."

The most convenient path to a valuable, reliable timestamp certificate — with less time, less effort, and less risk of infringement. That is what sets us apart.

Trusted by independent creators worldwide

Certification uses the public SHA-256 algorithm (FIPS 180-4), computed on your device. Keep your source file safe so you can trace and verify the certificate later. After timestamp certification, the "fingerprint" is written to the public operations log and anchored in Bitcoin. IdeaProofNow is timestamp certification for creative work.

Verify certificate

Keep your source file and timestamp certification safe; verify and trace when needed.

We do not store your source work. You keep it yourself. After certification you receive a unique code; anyone can use that code to trace the timestamp certification of that draft. The timestamp certification uniquely matches the source file.

  1. 01

    You stamp the work and receive a certificate ID.

  2. 02

    You send the ID, or print it in the work notes.

  3. 03

    The other person opens the verify page, enters the ID, and reads the time and fingerprint. They may upload the same file to match the hash.

Several steps in one place

No need to prove when you first created the work; share it openly without fear of challenge.

01 Stamp

Date the work

The browser computes the fingerprint. The same file matches on any computer. One changed pixel yields a new digest. The certificate stores the time and the ID. You keep the original.

02 Lookup

The ID is public

No login required. Enter the ID you were given and read when the fingerprint was recorded. Upload the same file to confirm the contents were not altered.

03 Operations log

Time is not only in our database

Each fingerprint enters an append-only public list and is anchored in Bitcoin. The time is not only in our database.

04 Notice

Use our template if your work is copied

A DMCA-style draft for common marketplace forms. You send it. Platforms apply their own review. The text is a self-help template. Outcomes are not guaranteed.

Who it's for

People who must send work off their desk — designs, decks, photos, listings, game assets — before a client or platform has a copy. AI can remix pixels; it cannot rewrite a Bitcoin-anchored stamp time. IdeaProofNow leaves a checkable date so you can show those exact bytes were already in your hands.

  • 03Keep a copy that still matches the certificate. One changed pixel means a new stamp.
