Zero-PII Mode
La modalità Zero-PII disattiva il fingerprinting: nessuna caratteristica del browser o del dispositivo, nessun ID dispositivo, solo segnali comportamentali. Anche in questa modalità l'indirizzo IP viene trattato per la verifica (rate limit, paese di provenienza), ma non viene memorizzato in chiaro.
SilentShield is already privacy-first
Even in standard mode, SilentShield only collects metadata. Fingerprints are stored as irreversible SHA-256 hashes, IPs are subnet-masked, and no keystroke content or user agent strings are stored. Zero-PII Mode goes one step further by disabling fingerprinting entirely.
What Changes in Zero-PII Mode
When Zero-PII Mode is enabled, the following data collection is disabled:
| Signal | Standard Mode | Zero-PII Mode |
|---|---|---|
| Keyboard timing (IKI, dwell) | Collected | Collected |
| Mouse movements & entropy | Collected | Collected |
| Focus & visibility events | Collected | Collected |
| Scroll position | Collected | Collected |
| Canvas fingerprint (SHA-256) | Collected | Disabled |
| WebGL fingerprint (SHA-256) | Collected | Disabled |
| AudioContext fingerprint (SHA-256) | Collected | Disabled |
How to Enable
There are two ways to enable Zero-PII Mode:
Via Dashboard
Go to API Keys, select a key, open Widget Settings, and toggle 'Zero-PII Mode' on.
Impact on Detection Accuracy
In Zero-PII Mode, the scoring weights are redistributed. Fingerprint-based signals (10%) are moved to behavioral signals. Detection accuracy remains high for most use cases.
| Category | Standard Mode | Zero-PII Mode |
|---|---|---|
| Keyboard (IKI mean) | 30% | 35% |
| Keyboard (pauses) | 20% | 22.5% |
| Mouse (entropy) | 20% | 22.5% |
| Mouse (speed) | 5% | 5% |
| Context (focus/visibility) | 10% | 10% |
| Device capabilities (fingerprints) | 10% | 0% |
GDPR & Compliance
Zero-PII Mode is ideal for organizations with strict privacy requirements:
- No Art. 6 GDPR consent required for fingerprinting — because no fingerprinting happens
- Nessun accordo sul trattamento dei dati necessario per dati biometrici — vengono raccolti solo schemi temporali
- Fully compatible with DSGVO Art. 25 (Data Protection by Design and by Default)
- No data subject access requests (DSAR) for fingerprint data — because none exists
When to use Zero-PII Mode
Use Zero-PII Mode for healthcare, government, or financial forms where maximum privacy is required. For most websites, standard mode is already GDPR-compliant and provides better detection accuracy.
