| Summary: | 碩士 === 玄奘大學 === 資訊傳播研究所 === 98 === In the e-generation, the teaching method has been developed from traditional to digital stage very rapidly. Instructional Architect abbreviated as IA is a package of practical tools for digital organizations to learn and manage .It allows teachers to access online resources easily, and organizes the resources for students to practice. At the same time, it can also provide the resources for the general public to learn. However, this one-time tool depends mostly on teaching resources and digital materials. In order to explore the sufficiency of its resources, we will focus on the major issue of digital internet technology ─ information security, and choose information hiding as our research subject.
In this research, we studied the actual information-hided digital sources and discovered that NSDL serve a broad range of clients, but its content could not satisfy all levels of users. Searching the term “Information Hiding” or “Steganography” could be regarded as a full term in periodic papers, but under the IA system, “Information Hiding” could be regarded as a term with space and separate into two different words. Therefore, the IA system could acquire more information than the traditional one, but its accuracy is relatively low.
