Revealed: Blue Shield of California’s Secret Data Sharing with Google Exposed Millions of Private Health Records
In a significant development, health insurance leader Blue Shield of California has announced a data breach that impacts millions of patients. This breach involves the unauthorized sharing of sensitive health information with tech giant Google, raising serious privacy concerns.
Details of the Data Breach
On Wednesday, Blue Shield confirmed that it had been sharing private health data with Google since 2021, a practice that ceased in January 2024. The company only became aware of the breach in February of this year. The data shared included:
- Search terms used by patients on the Blue Shield website
- Insurance plan names and types
- Group numbers and personal demographic information
- Member account numbers and claim service dates
- Financial responsibility of patients
Impact on Patients
According to a legally mandated notification to the U.S. Department of Health and Human Services, 4.7 million individuals are affected by this breach. Notably, this figure exceeds Blue Shield’s reported membership of 4.5 million as of 2022, indicating that the breach may impact a significant portion of its customer base.
What Happened?
Blue Shield utilized Google Analytics to monitor customer interactions on its website. However, a misconfiguration led to the unintended collection of personal and health data. The insurer noted that Google might have leveraged this data for targeted advertising campaigns directed at individual members.
Responses and Consequences
As of now, it is unclear whether Blue Shield has requested the deletion of the compromised data from Google, or if the tech giant has complied with such a request. Representatives from both companies have not provided comments on the ongoing situation.
Broader Context of Data Breaches in Healthcare
This incident is not isolated. Blue Shield of California joins other healthcare companies that have faced scrutiny for sharing patient data. For instance:
- In 2022, Kaiser Permanente informed over 13 million individuals about a similar breach involving advertisers like Google and Microsoft.
- Emerging healthcare startups, such as Cerebral and Monument, have also faced challenges related to data privacy.
The Implications for Healthcare Data Privacy
The ongoing issues surrounding online tracking technologies in healthcare highlight the vulnerability of patient data. These tracking codes, typically embedded by tech firms, are designed to harvest user data, often without explicit consent.
