Pixel-burn Redaction A redaction method that renders document pages as images and permanently removes underlying text data, making recovery impossible. Unlike overlay redaction (which just covers text with a black box), pixel-burn destroys the original text layer entirely.
Verification Certificate A cryptographically signed JSON file (verification.json) that proves a document's authenticity. It contains document hashes, timestamps, and an Ed25519 signature that can verify the document hasn't been modified since export.
Client-Side Processing Processing that occurs entirely within the user's web browser, without uploading data to external servers. In RedactProof, your documents never leave your device - only cryptographic hashes are sent for certificate registration.
SHA-256 Hash A 256-bit cryptographic fingerprint that uniquely identifies a document's contents. Even a single-character change produces a completely different hash. Used to verify document integrity.
Ed25519 Signature A modern elliptic curve digital signature algorithm. RedactProof uses Ed25519 to sign verification certificates, proving they were issued by RedactProof and haven't been tampered with.
PII (Personally Identifiable Information) Any information that can be used to identify an individual, such as names, addresses, dates of birth, Social Security numbers, email addresses, phone numbers, and financial account details.
OCR (Optical Character Recognition) Technology that converts images of text into machine-readable text. RedactProof uses OCR to restore a searchable text layer after pixel-burn redaction (Pro and Team tiers).
Audit Trail A chronological record of all redaction activity, including what was detected, what was approved for redaction, and when exports were generated. Available on Pro and Team tiers for compliance reporting.
WebAssembly (WASM) A binary instruction format that allows high-performance code to run in web browsers. RedactProof uses WebAssembly to run AI detection models entirely in your browser.
Certificate ID A unique identifier (e.g., "rp_abc123xyz") assigned to each verification certificate. Can be used to look up certificate details at redactproof.com/verify.
