Research published this week by Parks Associates finds that the greater the amount of data a device collects, the less willing a user would be to share it in return for a health insurance discount.

For example, 42 per cent of pedometer owners would be willing to share data, but that drops to 26 per cent for those who use a sleep quality monitor. What's more, 35 per cent of US broadband homes said that they are "very concerned" about their personal health information remaining confidential.

"Monetary rewards are generally considered among the strongest incentives to generate consumer response, but the majority of connected health consumers are not ready to share their data in exchange for discounts on services or products at this time," said Jennifer Kent, Director, Research Quality & Product Development, Parks Associates, of the findings.
