A few reports are out (BBC, Reuters). The concept diagram is for research purpose. Currently the government of Taiwan is tracking more than 40k targets having to take home quarantine measures, and this is not enforced without heated debate. I did a quick draw and this is what we know so far about the “digital fence” system enacted. My personal position is: this is extremely intrusive.
警方再次呼籲民眾勿隨意製造、散布或轉傳涉及新型冠狀病毒肺炎疫情之不實、未經查證之訊息，是類案件於抗疫期間必依法速查嚴辦。另請民眾全力配合政府相關防疫措施，相關資訊可上疾管署網站查詢最新公告內容，並可加入衛生福利部疾病管制署之「疾管家」官方LINE帳號，接收最新的疫情及防疫知識；還可透過「美玉姨」、「My Go Pen」等網路訊息查證平臺辨識訊息真偽，全民一體共同防禦新型冠狀病毒感染之肺炎可能帶來之危害。
撇開 typo 不論，「美玉姨」和「My Go Pen」不是「網路訊息查證平台」，自然也無法達到「辨識訊息真偽」的用途。
這個系統畢竟不是「媒體資訊系統」，所以在「授權」的層級會有不同的狀況。媒體資訊系統的授權，在這個年代的台灣，大概壓縮得很扁平。要服務的需求，也非常單純。例如說，授權的層級有主編、編輯、記者、設計師、工程師等。一條新聞上到網站，只要能產生足夠的 traffic。只要沒有「假消息」的疑慮，這個新聞的網址要如何被散佈，內容如何修改，大概也不會有什麼問題。一篇報導能產生到不重複 IP 數萬甚至到上百萬的訪問量。
Hey everyone, check this out– I've been blocked by the International Civil Aviation Organization (@icao), a @UN specialized agency, for assumedly tweeting about the need for Taiwan's inclusion (not membership) in light of a global health crisis. 1/ pic.twitter.com/yEZur36xvp
由於「武漢肺炎」的嚴重性不在話下，相關的智庫人員和記者，也接連在推特上表示意見。AEI 智庫的訪問學人 Michael Mazza 立即表示：
1/2 Apparently @icao, an organization that the US funds to the tune of $20 million a year, is now blocking people for tweeting critically, though not at all unfairly, about Taiwan’s exclusion from the organization. https://t.co/kx0lj3xGir
Important thread on the #ICAO#Taiwan qu. ICAO’s characterisation of respected academics + analysts as launching a “campaign” based on “misinformation” is an assault on the truth. As I said before, the attempt to silence debate on vital issues of aviation safety is chilling https://t.co/BObXXsfffE
Both the head of ICAO and its social media manager appear to be PRC nationals. The org is an example of China’s growing leadership role in int’l orgs (graphic from @ForeignPolicy): pic.twitter.com/pvCeq5kNLd
Top 2% finisher at #SCBmarathon (13k) #Taipei yesterday. Okay result for a former sprinter like me but had run it fairly conservative this time (flying out to Tokyo the next day). Might be able to cruise at higher pace in Kaohsiung for the half (21k) three weeks away. Last race before Lunar New Year!
