ProofSnap - Digital Evidence

Capture web pages as court-ready forensic evidence. SHA-256 hashes, blockchain timestamps, eIDAS qualified timestamps.

Screenshots can be challenged in court. ProofSnap makes your evidence tamper-proof. One click captures any webpage as a blockchain-timestamped, digitally signed evidence package — court-ready under US Federal Rules of Evidence (FRE 901/902) and EU eIDAS Regulation 910/2014. 7-day free trial. 🛡️ Why ProofSnap A regular screenshot can be forged in 30 seconds with browser DevTools. In *United States v. Vayner*, a federal court rejected a Facebook screenshot for lack of authentication. ProofSnap ensures your evidence holds up — with metadata, timestamps, chain of custody, and cryptographic proof. 🛡️ Provenance Certificate — Anti-Deepfake Every capture includes a Provenance Certificate PDF proving evidence was captured live from a real browser, not AI-generated. Eight integrity checks verify device, time, DNS, and TLS. Meets proposed FRE 707 (2025) and EU AI Act Article 50 (August 2026). 🔒 Five Layers of Protection Auto-refresh before capture · SHA-256 cryptographic hash · RSA-4096 digital signature · Bitcoin blockchain timestamp · EU eIDAS Qualified Timestamp (Enterprise/Company plans). Plus ISO/IEC 27037:2012 chain of custody and device integrity scoring. 📦 Evidence Package Contents Full-page or visible-area screenshot, complete HTML, DOM text, forensic metadata (URL, timestamps, TLS, cookies), SHA-256 manifest with RSA-4096 signature, blockchain proof (.ots), tamper-evident forensic log, ISO 27037 chain of custody, Provenance Certificate PDF, court-ready evidence report. Self-contained ZIP. 🎥 Optional Video Recording — Three Modes Auto (1-click, records the capture process), Manual (user-driven for media playback like livestreams or YouTube videos), Session (multi-tab continuous recording). All hashed, signed, and blockchain-timestamped alongside other files. For 30-min recordings with audio capture, see Video SnapPack below. 🗂️ Session Capture — Multi-Tab Forensics Document an entire browsing session as a single evidence package. Every visited http(s) tab gets full-page screenshot, HTML, DOM text, DNS cross-verification (Google + Cloudflare DoH), WHOIS lookup, TLS info, per-tab chain of custody, and signed evidence.pdf. Session-wide screen recording bundled. Ideal for compliance audits, fraud investigation, journalism, and IP enforcement. 📁 File Certification Drag-and-drop any file. Each gets SHA-256 hash, RSA-4096 signature, blockchain timestamp, and Provenance Certificate. Batch supported. Enterprise plans include eIDAS qualified timestamps.
