Abstract: Data space technology has become one of the key technologies to protect data sovereignty and release the value of data elements. Aiming at the problems such as data departure from domain, lack of trust between participants, difficulty in data sharing, and low efficiency of large-scale data exchange, this paper discusses the data self-aware access technology in data space, aiming to enhance the trustworthiness, security, transparency, and measurability of data sharing, circulation, exchange, and transaction. The research adopts Apache Pulsar and anomaly recognition-based perception technology to build a full-process data self-aware access platform, which provides a technical architecture for building a data infrastructure that supports massive, multi-source, heterogeneous, and multi-type data.

可信數據空間(Trusted Data Matrix, TDM)作為一種新興概念,可被視為數據資源共享的數字化基礎設施[4-5]。TDM旨在促進不同利益相關方在維護數據主權的前提下,實現數據的可信、安全、透明共享與交換。數據空間的概念最初在歐洲提出,并伴隨著國際數據空間(International Data Space,IDS)參考架構的發布,為各類企業提供了產品研發的理論基礎[6]。
