Google’s ‘Project Nightingale’ Gathers Personal Health Data on Millions of Americans

Google is engaged with one of the country’s largest health-care systems to collect and crunch the detailed personal health information of millions of Americans across 21 states.

The initiative, code-named “Project Nightingale,” appears to be the biggest in a series of efforts by Silicon Valley giants to gain access to personal health data and establish a toehold in the massive health-care industry. Amazon.com Inc., AMZN -0.80% Apple Inc. AAPL 0.79% and Microsoft Corp. are also aggressively pushing into health care, though they haven’t yet struck deals of this scope.
