Prompt Scrubber Nano (PII Shield)

The Prompt Scrubber Nano, also known as PII Shield, acts as a critical security layer between your applications and external Large Language Models (LLMs). Its primary mission is to prevent the unintentional leakage of sensitive data, helping you meet stringent data protection regulations like DSGVO/GDPR.

Key capabilities include:

• Intelligent Detection: Utilizes a hybrid approach combining regular expressions (Regex) and advanced Machine Learning-based Named Entity Recognition (ML-NER) to accurately identify a wide range of PII (names, addresses, contact details, financial info, health data) and other defined sensitive data types.
• Flexible Sanitization: Offers various methods to handle detected data, including:
  • Masking: Obscuring data (e.g., john.doe@example.com → ***@***.***).
  • Tokenization: Replacing data with a reversible placeholder (e.g., john.doe@example.com → <EMAIL_123>), with original data stored securely for optional re-identification.
  • Pseudonymization/Synthetic Replacement: Replacing data with realistic but fake data.
• Configuration and Control: Allows fine-tuning of detection rules, sensitivity thresholds, and whitelisting/blacklisting to match specific organizational needs and reduce false positives.
• Auditability: Provides detailed logs of scrubbing actions, which are essential for compliance reporting and security audits.
• Seamless Integration: Designed for easy deployment as an API gateway plugin, a library within your backend services, or a standalone proxy, minimizing disruption to existing workflows.

By implementing the Prompt Scrubber Nano, organizations can confidently leverage the power of LLMs while maintaining control over their data, reducing legal risks, and building a foundation of trust with their users. It’s an indispensable tool for anyone serious about AI ethics and data governance.
