隨著科技的進步及網路的普遍化，使得智慧型行動裝置快速崛起，在市場中占有重要地位且普及率日漸提升。近年來，智慧型手機已漸漸地影響了人們的生活型態，成為許多人生活中不可或缺的一部分。現今許多的系統，不論是銀行金融、電子郵件信箱、各大購物網站、論壇討論區等，為了確保安全，都需增設帳號密碼，因此在日常生活中我們將需記得許多不同的密碼，而傳統使用紙筆記錄下密碼的方式不但不安全且已不符合人們的需求，因而逐漸被智慧型手機上的密碼管理軟體所取代。目前市面上的密碼管理軟體大多沒有對暴力破解法做防範且系統欄位格式皆為固定，導致系統可能有被破解密碼的疑慮和使用者受到系統格式限制而不能任意輸入資料的缺點。
本論文實現了在iOS平台上開發一套應用於iPhone的密碼管理系統來輔助使用者管理紀錄其密碼資訊，日後使用者將只需記得一組密碼即可。本系統讓使用者以自訂資料夾及項目欄位的方式來做分類管理；依添加的附加功能，點選資料內容即可連結瀏覽器或撥打電話，使得操作上更加簡單便利。而存放於系統內的資料數據均受AES-256位元加密技術的保護，可有效防止駭客竊取。透過系統的仿真虛擬資料也可防止他人暴力破解出真實密碼。系統更提供了雲端備分和一鍵還原功能，讓使用者不再害怕紀錄資料的消失。本系統將帶給使用者安全且完善的密碼管理效果。

Along with the advance of technology and the Internet generalization, the application of the Smartphones becomes very popular. In recent years, the Smartphones have gradually affected people's life. In order to ensure security of personal data, users often have to memorize accounts and passwords for different systems such as financial institutions, E-mail, shopping sites, forum and so on. How to simplify the password management is very useful and worth. However, Apps currently on the market are unable to prevent brute-force attacks or unsuitable for systems with format restrictions that might result in several shortcomings; for example, systems may be cracked by hackers or users cannot input data.
In this thesis, we developed a password management app on iPhone used to assist the users to manage their password information. Consequently, users only need to memorize a single password. Also, users can customize folders and item fields so as to achieve classification management. By advanced settings, the data content clicked by users will automatically link to the browsers or phone calls, which makes the app more easy to use. Specially, the data that stored in the system will be protected by 256-bit AES encryption, so it can effectively prevent personal data from illegal access by hackers. By using virtual simulation data, the system can get rid of brute-force attacks. This system supports backup and restoration to/from Cloud, and provides more convenient usage for password management.
