憑證機制於詐騙電話防治之應用

隨著科技的日新月異，我們生活中擁有更多方便的資源。從前，相隔兩地的人要彼此問候、取得聯繫，是非常不容易之事。自從電話發明以來，地球上人與人間的溝通變得不受空間限制，即使身處地球兩端仍可隨時交談。電話無疑讓人的生活更加便利，但事情都有兩面的，電話在帶給我們利益及方便的同時，有心人士卻也利用其便利性，使用電話進行詐騙，讓許多電話之使用者聞詐色變，對於每一通電話都抱著消極懷疑的態度，甚至覺得乾脆別接電話就不會受騙上當。為了讓大眾能享有電話之便利卻不矇受詐騙之害，在此篇論文提出將憑證機制運用於電話之中，運用一般家庭擁有之設備，及政府所推行之憑證制度，讓電話之接聽者能夠知道來電者之身份，以降低來電顯示錯誤而無法確認來電者身份所造成之遺憾。
