    Abstract: 由於近年來晶片設計產業蓬勃發展與外在競爭激烈環境下,相關企業已跳脫早期以硬體為主的經營方式。取而代之採用的是軟、硬體相互搭配的營運模式。這概念已經成為目前市場主流。如:電視、手機晶片開發商紛紛投入大量資源於相關應用軟體開發。應用軟體對於生產銷售的成敗進而產生重要的影響。晶片設計產業的從業人員往往都需透過相關程式碼循環不斷的進行除錯及新功能的開發。過程是如此容易剽竊或洩漏, 因此企業內部對於相關應用軟體原始程式碼進行嚴格控管,來防範程式碼的剽竊與外洩事件發生。所以一個具有安全性高、方便性佳又能夠符合企業需求的資料交換平台是不可或缺的。資料外洩或篡改的防範是近年來一個十分熱門的資訊議題,其上述概念主要是透過文件內容的相似度比對來判斷資料風險程度的資訊安全方案。本研究將沿用這種概念 應用在企業內部的資料交換平台。 本研究將著重在C程式碼,透過C程式碼的分類特徵取樣與結合權重式Jaccard係數作為相似度判斷的基礎。並運用FTP代理程式來實作一個資料交換平台。After flourishing development of IC design industry, the design industry has evolved into a keen competitive industrial environment. Related enterprises thus have to get away early hardware-oriented operation mode and combine software with hardware into operation -oriented mode instead. This application-oriented conception is widely adopted and becoming the mainstream of IC design industry. Such as: chip developers of TV and smart phone have devoted considerable resources to related application software development. Application software for production and marketing in turn have major influence on the success of product sales.Designers of chips require high frequency of teamwork code developing, retrieval and debugging. The process is then so vulnerable to plagiary or leakage. To prevent incidents of leakage or plagiary of program code, enterprises all enforce their application source code to be strictly regulated. A highly secured, convenient and strict discipline-regulated data exchange platform to meet enterprise needs is therefore essential.In recent years, prevention of data leakage and distortion is a popular topic of enterprise information administration. The above concept is a mechanism that compares the similarity of document contents to detect and determine the risk level of security. In this study, we will apply the concept and implement an enterprise document exchange platform.The study will utilize "Source code classification feature sampling" of "C" language integrated with weighted "Jaccard coefficient" and running the enterprise document exchange platform on FTP proxy.
