WHAT INFORMATION IS INVOLVED IN THE DIGNITY HEALTH LASSEN MEDICAL CLINIC DATA BREACH?

The type of compromised information varied among individuals and potentially included: 

  • Names,
  • Addresses,
  • Dates of birth,
  • Driver’s license numbers,
  • Financial account information
  • Medical information. 

This information is called your Personally Identifiable Information (“PII”). It tells others about you and is considered part of your identity. Businesses are required to secure this information or risk facing statutory penalties, among other legal penalties. Stolen PII can be used by identity thieves to engage in fraudulent activity using your identity. 

Personal medical information (a specific type of PII) is referred to as Protected Health Information (“PHI”). It is protected under both state and federal law. Healthcare providers and other businesses who handle PHI are required to protect that information. Like stolen PII, stolen PHI can be used by identity thieves to engage in fraudulent activity using your identity. Quite often, PII and PHI are used in conjunction by hackers.

The best way to protect yourself after a data breach is to sign up for credit and identity protection services as soon as possible. 

California offers extra protections and legal rights to its residents through the California Consumer Privacy Act (“CCPA”).
