Paper Abstract:
|
More and more health records are stored in electronic form due to many advantages. From information science point of view, the Electronic Health Record (EHR) can be considered as a virtual container that can store health-related lifetime documentation concerning single patient. The security measures used in the EHR systems must evolve together with complexity and size of the systems. In this paper, a concept of new security property for EHR systems, called Long-Term Records Non-repudiation (LTRN), is introduced. The main idea of LTRN is to provide users with the confidence, that EHR is genuine and all documents are present in the exact order they were added. Apart from storage errors in the system, there is an issue of unauthorized changes detection caused by intruders and system administrators or other users that might have privileged access to system, that could allow them to modify (add/remove/delete) data from users EHRs, e.g., to change patients test results to justify some medical errors or to swindle money from insurance. The LTRN is an additional layer of security, which allows to ensure that a physician has made a diagnosis based on genuine content of the EHR. |
