本研究分析 2010 年至 2022 年間 168 件台灣及中國與詐騙有關之新聞案例及台灣各縣市警察局所刊登之詐騙案例，並以台灣及美國所提出的詐騙類型為基礎，將所蒐集的 168 件案例利用根本原因進行分類，提出完整的一套詐騙類型。針對各詐騙案例找出其促使案例發生的接觸媒介與交易媒介，並將各媒介進行編碼，接著應用卡方自動互動檢視法(CHAID)透過逐次搜尋處理屬性間的相互關係，以驗證媒介與類型之間的關係。

本研究所提出的詐騙類型共有十四種，分別為假親友詐騙、愛情詐騙、工作詐騙、投資詐騙、預付費詐騙、人頭帳戶詐騙、恐嚇詐騙、假客服詐騙、假檢警詐騙、未收到商品詐騙、商業電子郵件詐騙、略讀詐騙、釣魚詐騙及駭客詐騙。一系列的詐騙類型流程圖是依照 CHAID 分析結果所建構出來的，每一詐騙流程圖可清楚說明受害者是透過什麼樣的接觸媒介遇到犯罪者，再透過什麼樣的交易媒介交付出金錢或個人資訊及物品。最後，將針對各詐騙類型提出使該詐騙類型發生之機會點。

This research analyzes 168 fraud-related news cases in Taiwan and China and fraud cases published by police stations in Taiwan's counties and cities from 2010 to 2022. Based on the types of fraud proposed by Taiwan and the United States, the collected 168 cases that are categorized by root cause to present a complete set of fraud types. For each fraud case, find out the information media and money media that caused the case to occur, encode each media, and then apply the chi-square automatic interactive inspection method (CHAID) to process the relationship between attributes
through successive searches to verify the relationship between media and type.

There are fourteen types of fraud proposed in this study, namely, fake identity
fraud, romance scam, job scam, investment fraud, advance fraud, money mules scam,
intimidation fraud, tech support scam, government impersonation fraud, email account
typos, skimming scams, phishing scams and hacking scams. A series of fraud type flow
charts are constructed according to the results of CHAID analysis. Each fraud flow
chart can clearly illustrate the information media through which the victim encounters the criminal, and through which money media is used to deliver money or personal information and items. Finally, for each type of fraud, the point of opportunity for that type of fraud to occur will be presented.
