Machine learning advancements in healthcare have made data collected through smartphones and wearable devices a vital source of public health and medical *** wearable device data help to monitor,detect,and predict diseases and health conditions,some data owners hesitate to share such sensitive data with companies or researchers due to privacy ***,wearable devices have been recently available as commercial products;thus large,diverse,and representative datasets are not available to most *** this article,the authors propose an open marketplace where wearable device users securely monetize their wearable device records by sharing data with consumers(e.g.,researchers)to make wearable device data more available to healthcare *** secure the data transactions in a privacy-preserving manner,the authors use a decentralized approach using Blockchain and Non-Fungible Tokens(NFTs).To ensure data originality and integrity with secure validation,the marketplace uses Trusted Execution Environments(TEE)in wearable devices to verify the correctness of health *** marketplace also allows researchers to train models using Federated Learning with a TEE-backed secure aggregation of data users may not be willing to *** ensure user participation,we model incentive mechanisms for the Federated Learning-based and anonymized data-sharing approaches using *** authors also propose using payment channels and batching to reduce smart contact gas fees and optimize user *** widely adopted,it’s believed that TEE and Blockchain-based incentives will promote the ethical use of machine learning with validated wearable device data in healthcare and improve user participation due to incentives.
