GetProofAnchor: Tamper-Evident Web Evidence Capture and Verification

GetProofAnchor is a specialized tool designed to capture public URLs and social media posts as tamper-evident evidence. It transforms simple screenshots into legally robust, verifiable records. Unlike standard screenshots which are easily challenged regarding their source, time, or integrity, GetProofAnchor creates a structured, integrity-checked record that can be independently verified by third parties, legal counsel, or compliance teams.

Benefits

GetProofAnchor offers several key advantages over traditional methods of capturing web content. It provides tamper-evident integrity by detecting any modifications to the captured files. If someone alters the evidence later, the verification process will expose the change immediately. The tool ensures portability by packaging evidence into a portable ZIP file that can leave the platform while preserving its ability to be verified. It also guarantees vendor independence because it is built on open standards. If the service shuts down, the evidence remains verifiable by anyone with the ZIP file since verification relies on open standards like eIDAS and the Bitcoin blockchain. The workflow is fast, allowing users to capture evidence in approximately 30 seconds without leaving the browser. The system uses a four-layer trust stack to ensure the evidence is cryptographically intact. This stack includes SHA-256 file manifests, an append-only hash chain, a Bitcoin open timestamp anchor, and an eIDAS qualified timestamp. This multi-layer approach makes it very difficult to defeat the integrity of the captured data.

Use Cases

GetProofAnchor is tailored for scenarios where content may change, be edited, or disappear. It is useful for proving which version of terms and conditions applied at the time an order was placed. It helps users capture posts, profiles, or comments on social media before they are deleted or removed. The tool is valuable for documenting harmful claims or edited articles before they are altered to protect reputation and defend against defamation. It assists in verifying promises regarding pricing, guarantees, or service level agreements during client and vendor disputes. Compliance and audit teams can use it to archive policies and privacy wording for legal review. The Evidence ZIP package is designed for sharing with lawyers, compliance teams, or third-party reviewers. It contains the screenshot, extracted content, proof metadata, a manifest with SHA-256 hashes, an eIDAS timestamp, and a blockchain anchor.

Additional Information

GetProofAnchor works in Chrome, Edge, and Opera browsers. The tool supports chain of custody principles by ensuring content integrity, capture time, and traceability. While GetProofAnchor provides verifiable integrity and evidence workflows, it is not legal advice. Admissibility and evidentiary weight depend on jurisdiction, procedure, and specific circumstances. However, the eIDAS timestamp provides a legal presumption of integrity in EU member states. For inquiries or to discuss specific workflows, users can contact support at hello@getproofanchor.com.
