ZTDS (Zero Trust Data Sanitization) The In-RAM AI Security Standard & Method
Airplane-Mode Privacy for AI. Your customer records, financial figures, and confidential prompts never leave the host device. ZTDS physically stops sensitive data from ever reaching external clouds: masked in volatile memory, verified by cryptographic proof, with 0.00 bytes data leakage and zero GDPR Article 28 subprocessor liability.
* Conformance claims apply when implementations satisfy all 4 ZTDS RFC v1.0 invariants as verified by the Perimeter Scanner. This does not constitute legal counsel. Consult qualified privacy counsel for jurisdiction-specific compliance.
The ZTDS Method vs. Legacy Cloud DLP
Traditional enterprise security relies on intermediate cloud proxies that intercept cleartext traffic, introducing latency and adding third-party subprocessor liability under GDPR Article 28. The ZTDS Method moves the security boundary into volatile process memory: raw PII never crosses the network socket.
Cloud DLP & Proxy Gateways
[REDACTED] breaks grammatical syntax, destroys LLM attention weight matrices, and produces hallucinatory responses.
In-RAM Client Sanitization
[PATIENT_1], [IBAN_1]), preserving LLM reasoning and grammatical concordance.

The 4 Foundational Invariants of RFC v1.0
ZTDS is not a proprietary black box. It is a mathematical specification defined by four inviolable system invariants verified through automated network socket inspection.
Zero External Egress Prior to Sanitization
No personal data (PII, PHI, commercial secrets) may leave the local boundary in unmasked form. Enforced via socket byte-counting and audited via npx ztds-audit.
Deterministic Reversible Tokenization
Surrogate tokens preserve syntactic structure, grammar, and semantic roles for LLMs. The reverse mapping table is held strictly in volatile RAM for localized detokenization.
Verifiable Memory Isolation
Ephemeral mapping tables cannot be written to disk, databases, localStorage, or third-party telemetry sinks. They auto-destruct when the execution session ends.
Complete Subprocessor Exclusion
Software functions purely as a local computing utility. Under GDPR Recital 26 and EDPB doctrine, zero vendor processing of PII means no subprocessor chain and no DPA required.

Deploy the Method in 4 Lines of Code
Deploy using the vendor-neutral open reference package @ztds/core (Apache 2.0) or the enterprise production engine @privacyscrubber/sdk. Both execute 100% locally in WebAssembly or host RAM without external API keys, telemetry, or network calls.
// 1. Install open engine: npm i @ztds/core (or @privacyscrubber/sdk for enterprise profiles)
import { ZTDSClient } from '@ztds/core';
// 2. Initialize in-memory zero-trust enclave
const ztds = new ZTDSClient();
// 3. Sanitize prompt in volatile RAM prior to external egress
const { safePrompt, tokenMap } = ztds.sanitize(rawUserPrompt);
// 4. Transmit safe surrogate tokens to external cloud LLM (0.00 B PII leak)
const aiResponse = await openai.chat.completions.create({
model: 'gpt-4o',
messages: [{ role: 'user', content: safePrompt }]
});
// 5. Reversibly detokenize response locally in volatile RAM
const cleanResult = ztds.restore(aiResponse.content, tokenMap);
Why ZTDS-Compliant Architectures Do Not Require a DPA
Under GDPR Article 28 and EDPB doctrine, data processing agreements are legally required only when personal data is processed by a third party. Because the ZTDS Method executes 100% in client RAM with 0.00 bytes transmitted to vendor servers, the vendor never qualifies as a "data processor".
