可穿戴设备正在成为收集个人数据的有效模式。虽然这些数据可以用于从医疗保健到犯罪调查等多个领域，但在保护隐私和检测任何篡改企图的同时存储和安全访问这些信息是一项重大挑战。本文描述了一个分散的系统，确保个人的隐私，维护任何数据访问的不可变的日志，并提供分散的访问控制管理。我们提出的框架使用自定义的许可区块链协议来安全地记录区块链分类账中可穿戴设备的数据交易。我们已经实现了我们的框架的概念验证，我们的初步评估总结，以证明我们提出的框架的能力。我们还讨论了使用区块链和权威证明的隐私保护模型的各种应用场景。我们的研究旨在使用彻底的事务日志模型来检测数据共享场景中的数据篡改尝试。
Wearable devices are emerging as effective modalities for the collection of individuals’ data. While this data can be leveraged for use in several areas ranging from health-care to crime investigation, storing and securely accessing such information while preserving privacy and detecting any tampering attempts are significant challenges. This paper describes a decentralized system that ensures an individual’s privacy, maintains an immutable log of any data access, and provides decentralized access control management. Our proposed framework uses a custom permissioned blockchain protocol to securely log data transactions from wearable devices in the blockchain ledger. We have implemented a proof-of-concept for our framework, and our preliminary evaluation is summarized to demonstrate our proposed framework’s capabilities. We have also discussed various application scenarios of our privacy-preserving model using blockchain and proof-of-authority. Our research aims to detect data tampering attempts in data sharing scenarios using a thorough transaction log model.
