On the strength of the rapid development and propagation of U-healthcare service, the service technologies are full of important changes. However, U-healthcare service has security problem that patient's biometric information can be easily exposed to the third party without service users' consent. This paper proposes a distributed model according authority and access level of hospital officials in order to safely access patients' private information in u-Healthcare Environment. Proposed model can both limit the access to patients' biometric information and keep safe system from DoS attack using time stamp. Also, it can prevent patients' data spill and privacy intrusion because the main server simultaneously controls hospital officials and the access by the access range of officials from each hospital.

In this study, U-City to effectively manage information as a basis for studies of U-City Info characteristics were analyzed. U-City services are currently being discussed which is about 228. Short-term possibility of applying these services, the service's practicality and availability of services based on public services analyzed, 39 were selected. Next, the selected U-City to target services to analyze the flow of information and analysis based on the characteristics of U-City information was derived. U-City information derived from this study, the characteristics of real-time information, and service-specific mandatory and optional information, melting complex information, dynamic information, large amounts of data, user-customized information, and information security vulnerabilities, revealing personal information and privacy is. The results of this study, governments and municipalities to promote the construction of the U-City can be used effectively. To do so, considering the characteristics of U-City information, information management standards should be established.

Recently ubiquitous application services are developed plentifully using RFID techniques in the field of distribution and security industries. However, except these field the applications using RFID are not mature yet. In this study, we proposed a real-time context service model of the u-conference based on the real-time contextual information acquired from conference and exposition. With collection of real-time contextual information for u-conference, the model can provide a lot of information services on the state of session attendee, doorway control, affairs, user certification, presentation progress etc. For the verification of proposed real-time context service model of u-conference, we design and implement the conference progress state service included the state of session attendee, user certification and presentation progress etc. This service provides the presentation state information included the current presenter, the paper list, the number of session attendee, the schedule and place of each session using the collecting RFID tag and the related information.
