The Evolving Landscape of LLM Privacy Risks

The European Data Protection Board identifies critical privacy vulnerabilities across the entire AI lifecycle.

Input Data Risks

Users inadvertently send sensitive personal or corporate data in prompts, risking exposure, over-collection, and misuse by third-party AI services.

Output Data Risks

LLMs can memorize and regenerate sensitive information from training data or infer new personal details through linkage attacks and fabrication.

Training Data Risks

Personal data is often included in training sets without a valid legal basis, leading to significant compliance and bias issues.

Security Risks

Vulnerabilities like prompt injection attacks can be used to manipulate LLMs and exfiltrate sensitive, confidential information.

Privacy by Design: On-Device Protection

What the user types:

"Review contract for patient John Smith (DOB: 15/03/1980) regarding €25,000 treatment at Munich Medical Center, account DE89370400440532013000"
Umbrai Anonymizes On-Device

What AI services receive:

"Review contract for [PATIENT_NAME] regarding [AMOUNT] treatment at [FACILITY], account [IBAN_MASKED]"

Sensitive data never leaves your machine in its original form. LLMs receive only anonymized data, preventing memorization and ensuring GDPR compliance.
