When unapproved users access to healthcare system and use medical information for other malicious purposes, it could severely threaten important information related to patients` life, because in ubiquitous environment healthcare service makes patient`s various examination results, medical records or most information of a patient into data. Therefore, to solve these problems, we design RBAC(Role Based Access Control) for U-healthcare that can access control with location, time and context-awareness information like status information of user and protect patient`s privacy. With implementation of the proposed model, we verify effectiveness of the access control model for healthcare in ubiquitous environment. |
