This paper reviews RFID health authentication scheme based on location in the hospital. The designed handheld care system is implemented that are RFID reader/tag, an embedded Visual C++4.0, Pocket PC2003 software development kit (SDK) in an 802.11 wireless network. We are confident that the research provides sufficient proof of the usefulness of this ubiquitous health system for the collection of care information. The proposed system consists of a care management module for health diagnosis, a personal record module, a data transport module, and an image information management module for the clinic. System uses an applied security mechanism for critical data, and presents RFID authentication scheme, is accessed and controlled according to the location in the hospital.
