Those assurances are not true. WhatsApp has more than 1,000 contract workers filling floors of office buildings in Austin, Texas, Dublin and Singapore, where they examine millions of pieces of users’ content. Seated at computers in pods organized by work assignments, these hourly workers use special Facebook software to sift through streams of private messages, images and videos that have been reported by WhatsApp users as improper and then screened by the company’s artificial intelligence systems. These contractors pass judgment on whatever flashes on their screen — claims of everything from fraud or spam to child porn and potential terrorist plotting — typically in less than a minute.
I have noticed (and read) several accounts of healthcare facilities using WhatsApp to exchange patient information. I opposed it and wrote several emails (and letters to editors) that consumer grade technology cannot be adapted to the demands of healthcare privacy laws. This investigative report in one of the series of write-ups that document the privacy violations of users despite promises of “end-to-end” encryption.
It’s not clear exactly what government investigators have been able to gather from WhatsApp, as the results of those orders, too, are often kept from public view. Internally, WhatsApp calls such requests for information about users “prospective message pairs,” or PMPs. These provide data on a user’s messaging patterns in response to requests from U.S. law enforcement agencies, as well as those in at least three other countries — the United Kingdom, Brazil and India — according to a person familiar with the matter who shared this information on condition of anonymity. Law enforcement requests from other countries might only receive basic subscriber profile information.(emphasis mine)
The unencrypted data available for scrutiny is extensive. It includes the names and profile images of a user’s WhatsApp groups as well as their phone number, profile photo, status message, phone battery level, language and time zone, unique mobile phone ID and IP address, wireless signal strength and phone operating system, as a list of their electronic devices, any related Facebook and Instagram accounts, the last time they used the app and any previous history of violations.Anything and everything!
How can you trust Facebook despite their promises of “security”? Why do they need so much data?
It is time to discourage using WhatsApp in Healthcare.
