Abstract
To overcome the drawback of difficulties when interchanging a patient's health record among different health information management systems and yet keep the patient's privacy, this invention proposes a method comprising the steps of: extracting, from a certificate, a signature of a first service provider and a first identifier; generating a second identifier corresponding to the first identifier; sending a request to any one of a second identifier manager and the first service provider so as to request a record associated with the first identifier; receiving the requested record from any one of the second identifier manager and the first service provider; and associating the requested record with the second identifier. Use of the proposed method provides the advantage that there is no need to unify all health information management systems adopting the same pseudonymization service, and makes it easy to share health information among different health information management systems without disclosing the patient's privacy.
