摘要: | 得益於媒體壓縮技術的進步和寬頻網際網路的普及,多樣化多媒體網路應用的蓬勃發展,透過同儕網路(P2P)架構進行部署的IPTV服務興起。然而P2P IPTV所散布的多媒體內容大都具有智慧財產權(IPR),必須考慮如何有效地進行數位版權管理(DRM)。
此外,網際網路上多樣化的資訊服務持續發展,大量的用戶服務資料(包括了物聯網資料)也應運而生,處理和分析這些資料能為用戶提供更好的應用體驗。然而,這也帶來了資料傳輸與儲存的資源消耗與資料隱私問題。我們首先基於開放移動聯盟(OMA)的標準,提出了一個具有成本效益密鑰分配機制的P2P IPTV DRM架構,以改善投機性群播覆蓋網路(Opportunistic Multicast Overlays)上同儕節點的離開和加入對於P2P IPTV服務品質(QoS)與體驗品質(QoE)的影響。 為了解決傳輸與儲存大量用戶服務資料的資源消耗與資料隱私問題,本論文進一步提出了一個基於區塊鏈的資料市集平台。由於用戶服務資料在實際應用中有一定的誤差容忍範圍,因此,我們透過了有限誤差的資料壓縮與隱私保護的解決方案,利用區塊鏈的智能合約為用戶提供在不同服務層級下資料隱私的保護服務。並透過P2P星際檔案系統技術來提供安全的資料儲存和共享。在資料傳輸與儲存時,結合有限誤差資料壓縮技術,將能有效減少能源消耗。 實驗結果顯示所提出的P2P DRM方法在保護P2P IPTV電子商務服務系統的智慧財產權和用戶的QoS/QoE方面具有成本效益。此外,實驗結果也顯示在有限誤差1%下,感測資料約可達到40%的壓縮率。故透過區塊鏈與有限誤差技術可以有效實現建構節能與隱私保護的資料市集。 Thanks to the advancements in media compression technology and the widespread availability of broadband internet, diverse multimedia network applications have flourished. IPTV services deployed through Peer-to-Peer (P2P) architectures have emerged as a result. However, most multimedia content distributed through P2P IPTV is protected by intellectual property rights (IPR), necessitating effective Digital Rights Management (DRM) strategies. Furthermore, the continuous development of diversified information services on the internet has led to the generation of large volumes of user service data, including data from the Internet of Things (IoT). Processing and analyzing this data can enhance user application experiences. However, this also brings about concerns regarding resource consumption for data transmission and storage, as well as data privacy. We first propose a P2P IPTV DRM framework with a cost-effective key distribution mechanism based on the Open Mobile Alliance (OMA) standard. This aims to mitigate the impact of node departures and additions on Quality of Service (QoS) and Quality of Experience (QoE) in P2P IPTV services on Opportunistic Multicast Overlays (OMO) networks. To address the issues of resource consumption and data privacy in transmitting and storing large volumes of user service data, this paper further introduces a blockchain-based data marketplace platform. Recognizing the acceptable range of errors in user service data in practical applications, we present a solution for bounded-error data compression and privacy protection. By utilizing blockchain smart contracts, we offer users privacy protection services at different service levels. Additionally, secure data storage and sharing are facilitated through P2P InterPlanetary File System (IPFS) technology. Combining bounded-error data compression techniques during data transmission and storage can effectively reduce energy consumption. Experimental results demonstrate that the proposed P2P DRM method offers cost-effective protection for intellectual property rights and user QoS/QoE in P2P IPTV e-commerce service systems. Furthermore, the results show that with a bounded-error of 1%, sensor data can achieve a compression rate of approximately 40%. Thus, the combination of blockchain and bounded-error techniques can effectively realize the construction of an energy-efficient and privacy-protective data marketplace. |
