When WhatsApp announced it was introducing end-to-end encryption, it opened up the prospect of healthcare organizations using the platform as an almost free secure messaging app, but is WhatsApp HIPAA compliant?
Many healthcare employees have been asking if WhatsApp is HIPAA compliant, and some healthcare professionals are already using the text messaging app to send protected health information (PHI).
However, while WhatsApp does offer far greater protection than SMS messages and some other text messaging platforms, WhatsApp is NOT HIPAA compliant for several reasons.
Why Isn’t WhatsApp HIPAA Compliant?
First, it is important to point out that no software platform or messaging app can be truly HIPAA compliant, because HIPAA compliance is not about software. It is about users. Software can support HIPAA compliance and incorporate all the necessary safeguards to ensure the confidentiality, integrity, and availability of ePHI, but those controls can easily be undone by users.
HIPAA does not demand that encryption is used. Provided an alternate, equivalent measure is implemented in its place, encryption is not required. Since WhatsApp now includes end-to-end encryption, this aspect of HIPAA is satisfied.
Access controls are also required – See 45 CFR § 164.312(a)(1). This is one area where WhatsApp is not HIPAA compliant. If WhatsApp is installed on a smartphone, anyone with access to that smartphone will be able to view the messages in the user’s WhatsApp account, without the need to enter in any usernames and passwords. That means any ePHI included in conversations would also be accessible. Additional security controls may be installed on a smartphone to authenticate users before the device can be accessed, but even when those controls have been applied, notifications about new messages can often be seen without opening the App or unlocking the device.
HIPAA also requires audit controls – See 45 CFR § 164.312(b). This is another area where WhatsApp is not HIPAA compliant. Messages and attachments are saved, although they can easily be deleted. There is also no HIPAA compliant audit trail maintained in WhatsApp. All data in the account would also need to be backed up. Currently, if you switch phones, your account will be preserved, but your messages will not.
Then there is the issue of what happens to ePHI in a WhatsApp account on a personal device after the user leaves the company. Controls would need to be incorporated to ensure all messages containing ePHI are permanently erased. That would be a logistical nightmare for any covered entity, as it could not be performed remotely, finding messages would be next to impossible, and users would likely object to their WhatsApp being deleted.
Regardless of the features of WhatsApp and how well data is protected in transit, at the time of writing, WhatsApp will not sign a business associate agreement with a HIPAA covered entity. If HIPAA covered entities want to use WhatsApp, before any ePHI is sent, a HIPAA compliant business associate agreement must be signed with WhatsApp. Even though WhatsApp does not read text messages, that does not mean that no business associate agreement would be required.
So, Is WhatsApp HIPAA compliant? In its current form no. When it comes to WhatsApp and HIPAA compliance, even if covered entities were to use additional controls to prevent accidental disclosures, until WhatsApp is willing to sign a BAA, the service cannot be used to send ePHI without violating HIPAA Rules.
