    # Team 6 ## Hw1 ------------Pitcure----------- ![](https://i.imgur.com/Y8S0Gfo.jpg) -------Email Information------ **系統收信時間:2018/10/7/22:30 by TA** ------------Pow--------------- Nothing ------------Score--------------- **e.g. 80 by Team15 (TA)** ========================= ## Propasal ------------請在以下編輯----------- ## PPT https://docs.google.com/presentation/d/1NL0GyjmvNrynDnDBn1yUwdKNnYbUsodMb3PLi1hskyM/edit#slide=id.p # ExChain 區塊鏈期末報告 ## 現況描述 許多網站都會收集來訪使用者的瀏覽行為,並透過中心化的資料收集公司與其他網站交換去識別化後的行為數據,藉以建構更完整的使用者圖像,並應用於精準行銷。例如國內首屈一指的數據分析公司意藍科技媒合不同產業的網站提供 PeopleView 人群資料庫,提供企業了解會員的站外興趣、消費意圖和關注品牌,進而強化對會員的經營與行銷成效。 痛點定義 使用者端:GDPR 加強了可識別個資的保護,使用者所同意的眾多註冊條款中也通常包含禁止將可識別個人的資訊提供給無授權的第三方。然而一般無法識別個人的資訊不屬於個資,存在於交易市場並無觸法,然而使用者對於自己去識別化後的資訊會被交換到哪些地方卻是一無所知。 網站端:若想獲得其他網站數據,必須將自己的數據分享給中心化資料庫,無法完全掌握自己數據的流向與價值,也無法選擇要獲得特定個些網站的使用者生態。 ## 提案說明 建立一個去識別化的行為數據交易市場,提供使用者辨識願意公開交易紀錄的企業和行為數據的流向。由產生數據的企業作為供給端,需要數據的企業和廣告行銷公司等作為需求端。每個企業根據其市值決定一個動態調整的資料價格,而交易雙方必須將交易價格以及受交易的(去識別化後)使用者清單公開上鏈,提供使用者以裝置識別碼或其他資訊來追蹤個人數據的交易紀錄。交易結束後由買方為賣方評分,作為其他企業日後買賣的參考。 ## 技術架構 資料來源與交易格式:企業以自有資料預先分析會員的使用行為,將足以辨識個人的資訊去除。並為每個人貼上興趣(關注主題、商品)、消費意圖(與廣告互動的頻率)、屬性(使用地區、常用裝置)、品牌(關注品牌)四大標籤,此為共同交易格式。 交易:買方根據由賣方市值換算的資料價格支付流通貨幣給賣方,若買方給賣方評分,則平臺從買方抽取 0.5% 手續費,若無則抽取 1% 手續費。 應用區塊鏈:鏈上儲存企業間的資料交易記錄,提供使用者追蹤數據流向和企業交易行為,保證交易行為公開透明。使用者行為數據儲存在各自企業的資料庫,保留 GDPR 保障的被遺忘權。 實作:OurChain 作為底層架構記錄交易紀錄,desktop app 提供交易價格和選擇,同時在交易成立後以備購買方的私鑰與購買方的公鑰保證傳遞資料過程安全。 ## 使用場景 PC Home 知道自己的用戶在 KKBox 聽音樂的行為,則可以辨識出自己的用戶聽音樂的風格,並推薦耳機、音響相關的產品,如特別適合重低音樂的耳機。 華納威秀知道用戶在博客來的瀏覽和購買行為,則可以辨識出用戶喜歡小說和故事的風格,並推薦對應的電影,如推薦偵探電影給喜歡懸疑小說的讀者。 ## 競爭分析 #### eLand PeopleView 中心化的資料庫,透過語意分析、社群觀測等技術,搜集裝置的瀏覽特徵、行為,將裝置加上標籤。企業可以透過此資料庫更新用戶的興趣、關注品牌、消費意圖,藉此深化社群經營、達到精準行銷。
優點:擁有成熟的分析工具,能精準的設定標籤
缺點:使用者無法知道自己的紀錄被交易到哪裡,有個資的問題 #### Google Analytics 蒐集瀏覽該網頁的使用者的行為、特徵,讓管理者可以分析來此網站的客群、使用者類型,藉此調整網站的設計。
缺點:無法分析個別使用者的行為,也無法取得使用者在別的網站的行為 #### ExChain 優點:資料流向公開透明,用戶可以清楚自己的資料被交易到哪裡
缺點:沒有一個中心化機構幫忙搜集所有網站的資料,公司必須自己向其他公司要資料、無法控管平台外的交易行為 ## 潛在問題 使用者資料的真實性無法被衡量
不管是這個系統還是原有交易都會產生這個問題,我們的解決方法為將交易來源做評價,若作出的分析與投放廣告的效果不佳,則此資料可能有誤。對於資料來源作出評分,長久下來就可以避免掉劣質的資料,與劣質的公司。 一筆資料如何定義價格 目前使用市值(或股價)當作定義價格的參數 資料會不會被轉賣
歸類為道德問題,暫時沒有解答。不過如果使用者發現自己的資料從一個沒有接觸過的企業被賣出,就能知道該企業轉賣資料。不過如果使用者說謊就沒辦法了。 --- [Final Report](https://drive.google.com/file/d/10QA-TSu4oAIrPwdG7iMnI72BUk8WXN7x/view?usp=sharing) [Source Code](https://github.com/BCITeam6/)
