dc.description.abstract本論文將針對二維碼的資料安全、錯誤糾正以及二維碼讀取時容易發 生的問題,作深入的研究、分析,進而設計一可儲存中文字的二維碼系統 。在資料安全方面,本論文提出了一種新的概念,將資料分成一般資料和 機密資料,並將機密資料隱藏於二維碼中,以達成資料安全的目的; 在 錯誤糾正方面,選擇了錯誤糾正能力高的 Reed-Solomon code 處理更正 錯誤的問題;而在二維碼樣本的設計方面,本論文也分析了二維碼讀取時 容易發生的問題,設計可解決這些問題且可被快速讀取的二維碼樣本。實 驗結果顯示了二維碼樣本在破損、污損、旋轉、歪斜、縮放、燈光不穩等 情況下,本系統依然可更正錯誤並正確的讀取資料。另外,本論文將二維 碼應用在名片管理,製作成一個二維條碼名片管理系統。 In the thesis, we will develop a 2D code system and put emphasis on three topics: security, error correction and reading problems. The system can encodeEnglish, Chinese and special characters. About security, a new idea isproposed. The input data is divided into two parts: general data and secretdata. In order to achieve the security purpose, we hide the secret data in the2D code pattern which contains the general data and some extra codes for errorcorrection. In the part of error correction, the Reed-Solomon(RS) code withhigh error correction capability is chosen to recover errors. As to the designof the 2D code pattern, some reading problems are considered, these problemsinclude broken, noise, rotation, projection distortion, scaling and unstablelighting conditions. Experimental results are given to show that the proposedsystem is robust for these reading problems. Besides, we also design aname-card management system.zh_TW
