Web 2.0 時代使用者可以與其他使用者產生互動，允許使用者不只作為瀏覽者也可以是資訊提供的建立者，進而有了社交媒體的產生。Instagram 是一個主要以圖片和影片分享為主的平台，使用者可以透過各種功能分享日常生活和與他人互動。隨著現今社群平台蓬勃發展，社交媒體也開始結合電子商務功能，使用者不僅能能透過社群媒體與親朋好友交流、維繫感情，更能夠在上頭買到想要的商品或服務；然而，這些行為背後存在著資訊安全的風險。個人資訊、隱私、資訊安全在社交媒體上受到極高的關注，個人資訊以及隱私在社交媒體上尚未有明確區分範疇；資訊安全多半以預防性，像是提醒建置防火牆宣導。本篇研究採取半結構式訪談，試著從使用者角度探討他們認為在Instagram上屬於個人資訊的範疇定義、使用行為上對於個人資訊感到危機風險的意識以及就第264.3版介面使用上個人資訊保護的看法以及給予建議。本研究方向不只針對於自身個人資訊，在社交媒體超連結特性下，整個社群網絡皆是影響範圍；故也會針對使用下對於他人個人資訊的探討。研究發現，使用者對於Instagram個人資訊定義上可以廣義區分成兩大類，也發現在數位化時代下，對於保護個人資訊的理解變得更加重要，需要更加全面地考慮個人資訊的範疇；對於自己的個人資訊有較高的風險意識，然而，人們對於他人的資訊分享則存在著不確定性，這可能受到個人對於資訊敏感度的影響；介面的設計對於提醒使用者注意個人資訊的風險是有幫助的，個人化的功能和提醒視窗可以增加使用者對於個人資訊保護的意識，並給予他們更多思考是否分享的機會。本研究提供對於社交媒體上個人資訊保護的洞察，並給予未來在設計介面和提升用戶風險意識方面的一些方向。這對於社交媒體平台、用戶以及相關利益相關者都具有重要的參考價值。

In the Web 2.0 era, users can interact with other users, allowing users not only to serve as browsers but also as creators of information providers, leading to the emergence of social media. There are more than 19 million social media users in Taiwan, with the main platforms including LINE, Instagram, and Facebook. Instagram is a platform mainly for sharing pictures and videos. Users can share their daily lives and interact with others through various functions. With the rapid development of social platforms today, social media has also begun to incorporate e-commerce functions. Users can communicate and maintain relationships with relatives and friends through social media and purchase the goods or services they want online; however, there are information security risks behind these behaviors. For example, failure to hide personal information in limited-time updates may lead to data theft or the risk of being attacked by hackers. Personal information, privacy, and information security have received great attention on social media. Personal information and privacy have not yet been differentiated on social media. Information security is mostly preventive, such as reminders to build firewalls. The study not only focuses on individual personal information but also considers the impact on the entire community network under the hyperlink features of social media. Findings reveal that users broadly categorize personal information on Instagram into two main types. In the digital age, understanding the protection of personal information becomes increasingly crucial, necessitating a comprehensive consideration of the scope of personal information. Users exhibit a heightened awareness of risks concerning their own personal information. However, uncertainty exists regarding the sharing of others' information, influenced by individual sensitivity to information. Interface design plays a significant role in reminding users of the risks associated with personal information. Personalized features and alert windows can enhance user awareness of personal information protection and provide them with more opportunities to consider whether to share information. This study offers insights into protecting personal information on social media and suggests directions for future interface design and enhancing user risk awareness. It holds significant reference value for social media platforms, users, and relevant stakeholders.
