PII Leakage

PII leakage occurs when information that can identify or be linked to an individual is exposed to unauthorized users or systems. This can include names, email addresses, phone numbers, identification numbers, financial information, or other personal data. In AI applications, leakage can occur through prompts, model responses, logs, training data, retrieval systems, or connected tools.

PII leakage can create privacy, security, and regulatory risks for individuals and organizations. Preventing it helps organizations protect personal information and reduce the risk of unauthorized disclosure. Controls such as data detection, redaction, access management, and output filtering can help mitigate these risks.
