Researchers are using wearable cameras and location-tracking devices to observe how people behave in real life. They look at how daily behavior patterns relate to health. Some of the participants are not worried about the information captured by these wearable devices, some are. While there is an ethical framework to protect participants the challenge is how to share accumulated data with other scientists. How can we balance protecting participant privacy and advancing scientific methods, which require outsiders to repeat our analyses? (#30777)
