GoKawiilMuse headband maker InteraXon used brain data to train AI without telling users
A Science journal investigation found that InteraXon, maker of the $475 Muse EEG headband, used anonymized user brainwave data to train its AI brain model without disclosing this to customers until after being contacted by reporters. The investigation also reviewed dozens of other consumer EEG companies and found about a third had privacy policies that failed to clearly explain how brainwave data is handled, with four having no privacy policy at all.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest that oversight of brain-computer interface data has lagged behind scrutiny already applied to text, email and browsing data used in AI training. As AI investment grows, companies may have added incentive to repurpose biometric data like brainwaves for model training, which could raise concerns given the sensitivity of neural information even when anonymized.
- InteraXon trained an AI brain model using Muse headband data before disclosing this to users.
- About one-third of surveyed EEG companies had unclear or missing privacy policies on brainwave data use.
- Growing AI investment may be reshaping how brain-tracking wearable companies handle and monetize user data.
