摘要: | 隨著物聯網系統和應用的快速發展,產生了大量的感測器資料,處理及分析這些資料能為用戶提供更好的應用。在物聯網系統中,感測節點大多配置於無線的環境中且不易供電,因此無線感測節點仍具有耗電量的重要問題。由於實際應用上,物聯網系統通常具有其應用所容許的有限誤差範圍,在我們先前研究中提出了有限誤差資料壓縮,藉此延長物聯網系統的壽命。另一方面,物聯網巨量資料的儲存和共享往往必須仰賴於第三方服務供應商,因此也帶來了感測資料的隱私問題。為了解決這些問題,本研究提出了透過區塊鏈智能合約有效支援有限誤差資料的隱私保護方案(Bounded-Error Data Privacy Protection, BEDPP),並透過同儕網路的星際檔案系統技術提供安全的資料儲存與共享。該方案不僅有效延長了物聯網系統的使用壽命,且能根據智能合約中的權限和付款合約,為用戶提供不同服務層級下不同解析度感測資料的隱私保護服務。我們將所提出的方法在不同類型的感測資料上進行實測,實驗結果顯示,該方案可以透過保護資料隱私來延長物聯網系統壽命。 Due to the rapid development of Internet of Things (IoT) systems and applications,a large amount of sensors’ data has been generated. Processing and analyzing these data provide users with better applications in diversity. However, current wireless sensing nodes still have a significant issue of power consumption. As the application requirements usually have bounded-error tolerance in IoT systems, our previous research proposed bounded-error data compression to extend the lifetime of IoT system.Meanwhile, the IoT big data storing and sharing often rely on the third party service providers. It created another issues of data privacy. To solve these problems, this paper proposes a Bounded-Error Data Privacy Protection (BEDPP) scheme that effectively supports bounded-error data via blockchain smart contract and P2P InterPlanetary File System (IPFS) to provide secure data storing and sharing. The proposed BEDPP not only extends the lifetime of IoT systems, but also provides different levels of service quality in privacy protection according to the agreement of the rights and payment in smart contract. We use the proposed method on different types of IoT sensor data to experiment. Experimental results demonstrate that BEDPP can achieve IoT data privacy protection according to different error bounds acquired by users with extending IoT system life time cost-effectively. |
