Abstract:
Both confidentiality of privacy and the data sharing between healthcare practitioners are required in hospital information systems. A new access control method has been designed by the "patient-doctor relation and clinical situation at the point-of-care" model in addition to the traditional "account and password" mechanism. This method can; (I) allow flexible data access in need, (2) afford accurate access audit, (3) suppress inappropriate access.
