Data-harvesting big tech wants the secrets of your heart
The trillion-dollar question: who really owns the health data of millions of people?
Last week, at a conference in London, Dr Pearse Keane beamed an image on to the wall of an orange globe with a dark centre, encircled by red storms and a bright moon.
It looked like a dying planet in a distant galaxy. In fact, it was a beautifully detailed scan of the back of a human eye, as awesome in its own way as the night sky.
These days, Keane said, that single image betrays a lot of information. “We can now look at a retinal photograph and say: ‘This is a woman. She’s 58, she’s a nonsmoker. She’s not a diabetic, her BMI [body mass index] is around 25. And her blood pressure is 150 over 85. That’s pretty amazing.”..
