Last week, when Google gobbled up Fitbit in a $2.1 billion acquisition, the talk was mostly about what the company would do with all that wrist-jingling and power-walking data. It’s no secret that Google’s parent Alphabet—along with fellow giants Apple and Facebook—is on an aggressive hunt for health data. But it turns out there’s a cheaper way to get access to it: Teaming up with healthcare providers.

On Monday, the Wall Street Journal reported details on Project Nightingale, Google’s under-the-radar partnership with Ascension, the nation’s second-largest health system. The project, which reportedly began last year, includes sharing the personal health data of tens of millions of unsuspecting patients. The bulk of the work is being done under Google’s Cloud division, which has been developing AI-based services for medical providers.
