GetProofAnchor — Capture Web Pages as Tamper

What is GetProofAnchor?

GetProofAnchor captures web pages as tamper-evident evidence. It creates a verifiable record of what was visible online at a specific time and lets others later verify whether the evidence still matches the original captured state.

How is this different from a screenshot?

A screenshot shows appearance, but by itself it does not reliably prove source, capture time, or later integrity. GetProofAnchor adds structured metadata, cryptographic hashes, timestamps, and verification artifacts so later changes become detectable.

What does “tamper-evident” mean?

Tamper-evident means changes are detectable. If someone modifies the screenshot, page.html, extracted content, or another part of the package later, verification should show that the evidence no longer matches the original recorded state.

What is a Proof ID?

A Proof ID is the permanent identifier of a capture. You can share it as a reference and later use it to load the public proof record or connect it to an exported Evidence ZIP.

What is Evidence ZIP?

The Evidence ZIP is a portable evidence package. Depending on the capture, it can contain a screenshot, extracted content, page.html, proof metadata, a manifest with SHA-256 hashes, timestamp artifacts, and blockchain anchoring artifacts.

Why is the Evidence ZIP important?

It lets evidence leave the platform in a portable form while preserving later verifiability. Instead of sharing just an image, you can share a package that can be independently checked for integrity.

What is the manifest and why does it matter?

The manifest lists the files in the package together with their cryptographic hashes. During verification, hashes are recalculated and compared. If any file changed, verification should fail.

Can I verify the evidence offline?

Yes. The Evidence ZIP is designed for offline or independent verification workflows because it contains the files and integrity data needed to re-check whether the package still matches its original recorded state.
