The 4 Core Patented Inventions
PrivacyScrubber is built on breakthrough algorithmic and cryptographic systems designed to make data breaches mathematically impossible:
1. Client-Side DFA In-Memory Redaction
Deterministic Finite Automaton execution entirely within volatile browser RAM. Matches, classifies, and substitutes sensitive tokens (Names, PHI, Financial, Secrets) in a single descending index pass without creating persistent disk artifacts or outbound network sockets.
2. Zero-Knowledge Cryptographic Handoff
Peer-to-peer session transfer between team members using Argon2id key derivation and XChaCha20-Poly1305 authenticated encryption. Sanitization maps are transmitted directly between endpoints with zero server involvement, eliminating central database compromise vectors.
3. Air-Gapped stdio Agent Interception
An isolated Model Context Protocol (MCP) server operating over local standard input/output (stdio) channels. Sanitizes prompts, file reads, and tool calls before autonomous AI agents (Cursor, Claude Code, Windsurf) dispatch tokens to remote LLM APIs.
4. Zero-Subprocessor Statutory Exemption
An architectural structure that prevents PrivacyScrubber from qualifying as a third-party data processor under GDPR Article 4(8) or HIPAA 45 CFR § 164.502(e). Eliminates Data Processing Agreements (DPAs) and 6-week vendor security questionnaires by transmitting 0 bytes.
