由於全球大多數地區的網際網路基礎建設及行動通訊網路日臻成熟發達，無論是個人、組織、機構、企業、政府等個體(entity)，每日都在網路世界大量產生與其相關的數據或資料。過去，個體均需仰賴其他可以取信於公眾的其他個體之電腦資訊軟硬體系統及通訊設備，來對個體的身份及其所產生的數據或資料加以管理、進而控制。這些管理及控制身份與資料的個體，已經被證實無法安全保護所轄個體的身份隱私權、或是以壟斷資料所有權的方式來進行不公平的市場競爭。因此，身份自主權(self sovereign identity)的思潮運動已經從萌芽進入到成長階段，雖然尚未啟迪所有公民的自主意識，但是藉由區塊鏈技術的發展及採用，讓身份自主權已開始步入到實際應用上；而以身份自主權為基礎的資訊科技未來顛覆人類的生活方式實屬可期。

本文採用商業生態系統觀點為基礎，採用內容資料分析法，探討產業中主要領導的廠商、組織及團體，在自主權應用的發展所扮演的角色；並透過問卷調查進行量化分析方法，了解顧客群體從其他生態系統遷移到身份自主權生態系統的支持意願。冀望從資料整理分析之後，得出台灣地區從事業者進軍世界其他地區的發展策略。

With the advent of the construction maturity of Internet infrastructure and mobile telecommunication networks in the world, entities, whether individuals, organizations, institutions, enterprises, or governments, create tons of data and information in the cyberspace day by day. Before, entities need to rely on others’ computers as well as information software and hardware systems which are trusted by the public to manage and control their identities and related private data and information. However, some means of facilitating the management and controlling mechanisms of others’ identities and data have been proven incapable of securing the privacy of data or information kept in their hands. Others even corner the whole market by monopolizing the ownership of collected data. The ideological trend to adapt self sovereign identity has been rapidly burgeoned although the perception of it has not thoroughly known by all the citizens yet. However, the development of blockchain technologies propelling the according applications to the real world has been practiced and deployed . The information technologies building on self sovereign identity will definitely re-shape and innovate our future life.

On the basis of Business Ecosystem perspective, this study explores the roles of leading vendors, organizations, and groups playing in the development of Self Sovereign Identity by employing the methodology of content analysis. Via collecting questionnaires on the Internet and analyzing the data by a quantitative approach, we try to understand end users’ willingness to support the migration from other ecosystems to SSI. After the sight of the data analysis result, we expect to propose some development strategies to assist the engaged Taiwan vendors and operators in their entrance to international markets.
