本課程希望培養學生對於資訊隱藏相關的知識、概念，並透過實務資料分析培養學生問題解決能力。傳統的機密資料保障技術通常是利用加解密技術來成。透過將重要的機密資料進行加密的處理來將資料打散成亂碼；只有合法的接收者可以透過金鑰搭配解碼的處理來達成解密的動作。由於傳送加密後的資料還是會讓惡意的第三者察覺有重要的資料被傳輸，為了解決這個問題資訊隱藏的技術因此被提出。資訊隱藏技術會較為重要的資料藏於所利用的數位媒體(文字、影像、視訊…)之中，讓非法使用者無法透過人類感知系統來察覺機密、重要資訊的存在，避免其機密、重要資訊被攔截、破解，而達到保護的效果。
課程內容主要涵蓋不可回復資訊隱藏、可回復資訊隱藏、加密影像資訊隱藏等方法，並透過碩博士論文與科技論文的導讀與討論，了解各個資訊隱藏方法如何應用到真實世界的應用，進而有能力設計出改良的資料資訊隱藏技術。
教學目標:
1. 讓學生有資訊隱藏之專業知識
2. 學生需查詢博碩士論文與科技論文來閱讀現有資訊隱藏相關技術
2. 學生需分析個別資訊隱藏技術之優缺點
4. 學生需培養設計改良與創新的技術的能力This course hopes to cultivate students' knowledge and concepts related to information hiding, and to cultivate students' problem solving skills through practical data analysis. Traditional confidentiality data protection technology is usually achieved using encryption and decryption technology. Break the data into code by encrypting the process of important confidential data; only legal recipients can achieve decryption actions through key combinations of decoded processing. Since sending encrypted data will still allow malicious third parties to see that important data is transmitted, the technology to understand the hidden information of this problem has been proposed. Information hidden technology is more important data hidden in the digital media used (text, images, videos, etc.), allowing illegal users to observe the existence of confidentiality and important information through human perception systems, and avoid their confidentiality and important information. It is intercepted and cracked, and achieves a protective effect.
The course content mainly covers methods such as non-retrieval information hidden, retrieval information hidden, encrypted image information hidden, and other methods. Through the introduction and discussion of Doctoral Scholar and scientific and technological papers, we can understand how various information hidden methods can be applied to the real world, and be able to achieve the ability. Design improved data hidden technology.
Teaching objectives:
1. Let students have professional knowledge of hidden information
2. Students need to consult the Doctoral School and Science and Technology Papers to read existing information hidden related technologies
2. Students need to analyze the advantages and disadvantages of individual information hidden technology
4. Students need to develop the ability to design improvement and innovation technology
