Ultra-light privacy firewall for LLM prompts
Project description
hbp100
Ultra-light privacy firewall for LLM prompts.
hbp100 detects and masks common personally identifiable information (PII)
before text is sent to an LLM or another downstream service.
Install
pip install hbp100
Usage
from hbp100 import sanitize
result = sanitize("Email john@example.com and OTP 123456")
print(result.text)
# Email [EMAIL_1] and OTP [OTP_1]
print(result.metadata)
# {'[OTP_1]': '123456', '[EMAIL_1]': 'john@example.com'}
What It Masks
- Email addresses, phone numbers, URLs with tokens, API keys, bearer tokens, JWTs, passwords, OTPs, PINs, credit cards, IBANs, UPI IDs, government IDs, account identifiers, patient IDs, IMEI numbers, addresses, and similar data.
- Context-aware years: horoscope and calendar-conversion years can be kept while identity-related years are masked.
