Abstract
In this paper, we presented a new security approach to provide security measures and features in both healthcare information systems (PACS, RIS/HIS), and electronic patient record (EPR). We introduced two security components, certificate authoring (CA) system and patient record digital signature management (DSPR) system, as well as electronic envelope technology, into the current hospital healthcare information infrastructure to provide security measures and functions such as confidential or privacy, authenticity, integrity, reliability, non-repudiation, and authentication for in-house healthcare information systems daily operating, and EPR exchanging among the hospitals or healthcare administration levels, and the DSPR component manages the all the digital signatures of patient medical records signed through using an-symmetry key encryption technologies. The electronic envelopes used for EPR exchanging are created based on the information of signers, digital signatures, and identifications of patient records stored in CAS and DSMS, as well as the destinations and the remote users. The CAS and DSMS were developed and integrated into a RIS-integrated PACS, and the integration of these new security components is seamless and painless. The electronic envelopes designed for EPR were used successfully in multimedia data transmission.
