摘要:	隨著人們在社群平台上越來越活躍，各種消息在社群媒體的傳遞越來越難辨真假，一則假消息可能造成很大的不良影響，如何幫助社群媒體使用者辨別假消息，進而減少假消息的傳播愈來愈重要。因此本研究探討能否以眾人之智的方式解決社群平台上傳播假消息的情況，我們使用Chrome extension與區塊鏈在既有社群平台－ Facebook上防範假訊息的散佈，透過社群媒體使用者利用Chrome extension對Facebook上的消息來源及貼文進行投票，並記錄於區塊鏈上，藉由大量評分後判斷貼文是否為可相信的貼文或是有問題的假息，藉此判斷不同媒體發送訊息的可信度，以防範假消息在社群媒體大量傳佈。本研究實驗設計由研究者使用Chrome extension與區塊鏈結合於Facebook，使用者於Facebook的投票記錄能以區塊鏈方式紀錄於系統端，研究者選擇目標使用者做為訪談對象，包含新聞記者、社群小編與一般使用者，研究者在受訪者面前操作實驗系統後，請受訪者評估此套實驗機制及系統是否有助於防範社群媒體的假訊息擴散。根據本研究收集的受訪者回饋，大多數意見認為本研究所設計出系統架構可行，然而在眾人之智部分，則需待系統更為成熟之後，收集大量使用者回饋才能更進一步判斷能否以眾人之智的方式解決社群平台上傳播假消息的情況，本研究未來可以改進系統部分，例如發行平台虛擬貨幣促進使用者幫忙驗證區塊或鼓勵消息來源產出優質新聞、建立後台觀測平台讓新聞媒體得知現正被關注之議題等，使得本研究更為完善。 As people become more active on the social platform, the transmission of messages becomes more and more difficult to distinguish between true and false. Therefore, how to help social media users to identify fake news and reduce the spread of fake news is becoming more and more important. This research aims to solve the spread of fake news on social platforms with collective intelligence. This study uses Chrome extension and blockchain to prevent fake news on the existing social platform as Facebook, and process users votes, then records them on the blockchain. After a large number of ratings, it determines whether the post is a credible post and judges the credibility of messages sent by different media to prevent fake news delivery. The interviewees include news reporter, curator and general user. After the researcher operates the system in front of them, the interviewees are asked to evaluate whether the system help to prevent the spread of fake news in social media. Most of the feedback from interviewees, we received for this research, confirm that the system architecture designed by this research is feasible. Other future work to make this research more complete, includes the issuance cryptocurrency to encourage more users to participate or drive high-quality news produce, and establishing a content management system to let the media know about issues that are currently being watched.
