Secure search and preservation method of medical and health record -- Toward the construction of secure EHR --

Abstract (in Japanese) (See Japanese page) 
(in English) The EHR (Electronic Health Record) that accumulates clinical history of individuals over a lifetime is being deployed globally and expected to help patients healthcare and sharing information among medical institutions. However, fear of unauthorized use or disclosure of personal information is becoming a barrier of diffusion. Only with personal authentication and attribute based access control, the confidentiality of patient information cannot be protected against server attack. The best way is to encrypt the information, but encryption makes data processing and search inefficient. To resolve this problem, we implement the Patient Controlled Encryption (PCE) as proposed by Josh et al. and validate its feasibility in EHR system. PCE gives index to patient information that is encrypted with a patient-specific key and the category name, and then distributes the encryption key to those that qualified for the category. By doing this, decoding the information becomes possible by searching the index only within the category.
