# Capture the web as tamper-evident evidence â€” not just screenshots.

Turn what you see online into a proof you can use and verify. Capture public URLs or social media posts, export an Evidence ZIP with hashes, and show a clear integrity result: Match or Modified.

Why this holds up better than screenshots: evidence is designed to be tamper-evident. If someone alters captured files later, verification process expose the change.

Built for disputes, investigations, compliance workflows, and online content archiving.

## The 4-layer trust stack underneath every proof

Every capture is anchored in four independent integrity layers, each with its own files in the Evidence ZIP, each independently verifiable by a third party. Defeating any single layer doesn't break the others.

Layer 1
SHA-256 file manifest

Every file in the Evidence ZIP has its hash recorded in manifest.json. Editing a single byte â€” even reformatting whitespace â€” fails the integrity check.

Layer 2
Append-only hash chain

Each capture is part of a global SHA-256 chain. Each entry contains the hash of the previous one, so inserting or modifying any past entry breaks the chain mathematically.

Layer 3
Bitcoin OpenTimestamps anchor

The chain head is anchored to the Bitcoin blockchain. Once confirmed, the timestamp is preserved by the entire Bitcoin network â€” independent of GetProofAnchor.

Layer 4
eIDAS qualified timestamp

RFC 3161 timestamp from an EU-qualified Trust Service Provider (currently SK ID Solutions, Estonia). Recognized as legal-grade proof of existence at a point in time under Regulation (EU) 910/2014.

All four layers PASS â†’ the package is cryptographically intact, not just believable. Any layer FAILS â†’ modification is detected, with a per-layer report showing exactly which one was tampered with.

How it works

## Built for disputes, not just screenshots

Screenshots alone are easy to challenge. GetProofAnchor produces a structured, integrity-checked record you can reference and verify later.

01
Capture

Capture a public URL or what you see in your browser via extension.

02
Export

Export an Evidence ZIP with manifest, SHA-256 hashes, eIDAS timestamp and hash anchor in blockchain.

03
Verify

The integrity of the evidence can be independently verified, including the detection of any modification.

Important: GetProofAnchor does not judge truthfulness â€” it verifies integrity: whether a live page (or an evidence package) matches what was captured at a specific time.

## FAQ

Practical answers about evidence capture, verification, timestamps, and integrity.

### Basics

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 â€śtamper-evidentâ€ť 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.

### Evidence ZIP & verification

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.

### Hashes and timestamps

What is SHA-256 and why is it used? +

SHA-256 is a cryptographic hash function. It creates a fingerprint of a file or payload. Even a very small change produces a different hash, which is why it is useful for integrity verification.

What happens if someone edits the evidence files? +

If someone changes the screenshot, page.html, extracted content, metadata, or package structure, the hashes will no longer match the original manifest or timestamped payload. Verification should then report a mismatch.

What does an eIDAS timestamp prove? +

An eIDAS-qualified timestamp proves that a specific hash existed at a specific time, based on a trusted timestamping authority. It does not store the webpage itself; it timestamps the cryptographic fingerprint of the evidence payload.

What does OpenTimestamps / Bitcoin anchoring prove? +

OpenTimestamps anchors a cryptographic hash into the Bitcoin blockchain. That provides public, independently checkable existed-before evidence for that hash. Because the anchor is tied to the hash, it also supports later integrity verification.

Can someone edit files and just recalculate the hashes? +

Simply recalculating hashes is not enough. That would break the relationship to the original timestamp, manifest, or blockchain anchor. That is exactly why later manipulation becomes detectable.

### Legal and practical use

Can the captured evidence be used in court? +

Yes â€” that is exactly what the Evidence ZIP is designed for. A qualified eIDAS timestamp carries a statutory presumption of time accuracy and data integrity, and electronic evidence may not be denied legal effect merely because it is electronic. The assessment of any specific piece of evidence always rests with the court â€” which is why the package can be independently verified by the court and the opposing party alike.

Can I capture social media posts or logged-in content? +

Yes. The browser extension captures what you actually see, including authenticated pages you lawfully have access to.

Can I prove that content was later deleted or changed? +

Yes â€” if you captured it in time. The evidence shows what was published or visible at that moment, even if the page later changes or disappears.

What is chain of custody and why does it matter? +

Chain of custody describes how digital evidence is captured, handled, and preserved over time. For credibility, it is essential to demonstrate content integrity, capture time, and traceability of the evidence. GetProofAnchor supports these principles using cryptographic hashes (SHA-256), file manifests, timestamps (including eIDAS), and blockchain anchoring, ensuring that any modification of the evidence can be detected.

Frequent questions
Can the captured evidence be used in court?
Yes â€” that is exactly what the Evidence ZIP is designed for. A qualified eIDAS timestamp carries a statutory presumption of time accuracy and data integrity, and electronic evidence may not be denied legal effect merely because it is electronic. The assessment of any specific piece of evidence always rests with the court â€” which is why the package can be independently verified by the court and the opposing party alike.
Does â€śtamper-evidentâ€ť mean it canâ€™t be altered?
It means changes are detectable. A court-appointed expert or IT specialist will immediately recognise that the evidence has been tampered with â€” and anyone can verify it themselves with a free open-source tool.
