| Summary: | 碩士 === 國立交通大學 === 電機資訊學院碩士在職專班 === 93 === Nowadays, every company or organization has many kinds of different application systems. Users usually need to remember several combinations of user account and password to logon different kinds of application systems, even the related functions. When different companies or organizations are merged, users will suffer more painful work. Also, as the technology evolves daily, users may use many different kinds of devices (for example: desktop personal computer, notebook, PDA, mobile phone, or other mobility devices) to access web site or other related application systems. Users usually need to remember more IP address links or many combinations of account and password information.
For system managers, they usually need to spent more efforts on the system maintenance in order to support these different needs. System manager not only needs to maintain the heterogeneous applications, but also the heterogeneous contents and databases authentication. It is a very time-consuming activity.
In this thesis study, these problems mentioned above are addressed. Specifically, we investigate single-sign-on approach and content’s early binding approach to reduce the maintenance efforts and provide an easy way for users to logon these systems. Also a DRM mechanism is provided to achieve access control and created digital contents protection.
