Are Google Health’s Privacy Practices Healthy?

Friday, June 20th, 2008

by Jessica Young and Annie I. Antón

On May 19, 2008, Google launched Google Health [1], a new Personal Health Record (PHR) web portal that allows patients to gather and organize their medical records while keeping their physicians up to date about their health condition. As with other PHRs, like Microsoft’s HealthVault, Google Health does not appear to be covered by federal or state health privacy laws. According to the Google Health Terms of Service, Google is not a “covered entity” as defined in the Health Insurance Portability and Accountability Act (HIPAA); as such, “HIPAA does not apply to the transmission of health information by Google to any third party” [2].

Researchers at have evaluated privacy policies and privacy breaches since its founding in 2001. In particular, The Privacy Place researchers are addressing the extent to which information is protected in financial and health care systems that must comply with relevant laws and regulations.

Google Health is not a covered entity as defined in HIPAA. Thus, any personal health data that you submit to Google Health will not be afforded the same legal protections required of health care providers under HIPAA. Until state and federal agencies establish and enforce laws to protect the privacy of personal health records maintained by non-covered entities, individuals should carefully consider the risks involved in submitting sensitive health information to Google Health and other PHRs such as HealthVault. PHRs are not subject to the same privacy and security laws to which traditional medical records are subject to in the United States.

As with our analysis of Microsoft’s HealthVault [3] in October 2007, we encourage patients to carefully consider and question the privacy practices as articulated in the Google Health privacy policy, terms of service, and frequently asked questions. To further explore this new service, we analyzed and evaluated the protections and vulnerabilities involved in using Google Health. The Google Health Help Center provides a link and U.S. Postal Address—but no other contact method, such as email address or phone number —for users to submit a “Question About Privacy” [4]; clicking on this link displays a web page with a form for inquiries that states, “[w]e hope this information [Privacy Policy] will help you make an informed decision about sharing your personal information with us” [5]. Unfortunately, Google has been unresponsive to our questions regarding its Google Health privacy policy.

We sent four questions regarding Google Health’s privacy practices via the Google Health Help Center [5] on May 23, 2008. On June 4, 2008, we submitted the same four questions but this time via Google’s Web Search Help Center [6], where users are invited to submit questions specifically about Google’s privacy practices. It has been over three weeks since our first inquiry and we have yet to receive a response of any kind to any of our questions. Patients are concerned about the privacy of their health information [7]. A lack of prompt replies to questions regarding health privacy is disconcerting and suggests that privacy is not a priority for those managing Google Health or manning the Google Help Center.

We focused on three questions of Microsoft’s HealthVault in our previous analysis [3]. Here we examine these same three questions within the context of Google Health.

Will your health information be stored in other countries without appropriate legal oversight, skirting many of the protections afforded by the HIPAA?

The three Google Health privacy-related documents provide no insights about where personal health information will be stored. As we received no answers to our inquiries to the Google Health Help Center, we turned to the general Google Privacy Policy, which states, “Google processes personal information on our servers in the United States of America and in other countries” [8]. Users should always be concerned about the location of their data because different countries have different data protection standards and laws. If your data is breached in some way, the physical location of the server on which it was stored will affect the recourses that will be available to you.

Will your health care records be merged with other personal information about you that was previously collected within the context of non-health related services?

No, according to the documents we reviewed. Google Health’s Privacy Policy states: “The [record] log information will be used to operate and improve service and will not be correlated with your use of other Google services” [9]. This is also addressed in the FAQ by the statement that “no personal or medical information in your Google Health profile is used to customize your search results or used for advertising” [10]. At this point in time, it appears that Google Health information will not be merged with information from other Google services without your consent.

Are the access controls to your health records based not only on your consent, but also on the principle of least privilege?

Google Health allows users to grant read/write access to their information to other third-party sites and/or individuals. The Google Health Privacy Policy states: “you [as a Google Health user] can revoke sharing privileges at any time. When you revoke someone’s ability to read your health information, that party will no longer be able to read your information, but may have already seen or may retain a copy of the information” [9]. Thus, users should determine their access control rules as soon as possible when setting up their accounts. Access control rules and the ability to change these rules become immaterial once private health information reaches an unauthorized or unintended agent. Google is not clearly implementing the principle of least privilege, because it appears that others may be able to grant read/write access to your health information, leaving the door open for data breaches.
