5 Anonymization Methods

Choose the right protection level for your use case

Replace

Substitute PII with realistic fake data. Maintains document readability while protecting privacy.

// Before
"John Smith"

// After
"Max Mueller"

Redact

Completely remove PII from the document. Irreversible but maximum privacy protection.

// Before
"john@example.com"

// After
"[REDACTED]"

Hash (SHA-256)

One-way cryptographic hash. Enables consistent pseudonymization across documents.

// Before
"555-0123"

// After
"a7f3c9..."

Encrypt (AES-256-GCM)

Military-grade encryption. Fully reversible with the correct key.

// Before
"DE89370400..."

// After
"enc_xK9m..."

Mask

Partial visibility with masked characters. Shows structure while hiding sensitive parts.

// Before
"4532-1234-5678-9012"

// After
"4532-****-****-9012"

Privacy-as-Code

Structural protection — not a policy document

Traditional approach

  • AI usage policy document employees ignore
  • Manual checklist before every AI interaction
  • DLP alerts fire after data has left
  • No enforcement at the AI prompt layer
  • GDPR liability if one employee slips

Privacy-as-Code with anonymize.dev

  • PII interception is structural — MCP layer, not willpower
  • Every AI prompt anonymised automatically
  • Protection happens before data leaves your environment
  • Enforced regardless of which tool the developer uses
  • GDPR Art. 25 Privacy by Design — technically implemented

GDPR Art. 25 requires that data protection be built into system design. Relying on employees to manually avoid pasting PII into AI tools is not a technical safeguard — it is a policy. anonymize.dev makes PII protection a technical control: it happens automatically, at the infrastructure layer, every time.

OWASP Compliance Coverage

Which OWASP LLM Top 10 and Agentic AI risks anonymize.dev mitigates

OWASP Risk Category How anonymize.dev helps Coverage
LLM02 Sensitive Information Disclosure PII stripped from prompts before LLM processes them — real data never in LLM context ● Full
LLM06 Excessive Agency Anonymised prompts reduce the value of data an over-privileged agent can access or exfiltrate ● Partial
LLM07 System Prompt Leakage PII in system prompts anonymised via the MCP operators parameter before injection ● Partial
AA3 (Agentic) Sensitive Info Disclosure — Agentic MCP-layer anonymisation prevents PII from entering agent context windows in multi-tool pipelines ● Full
AA4 (Agentic) Tool Misuse / Tool Poisoning Even if a downstream MCP tool is compromised, it receives only tokens — not real PII ● Full
AA7 (Agentic) Data Exfiltration via Agent Autonomous agents with file/DB access operate on tokenised data — exfiltration yields no real PII ● Full
