Responsibility Certification System Based On Multiple Digital Signatures Of EMR Syste

Medical records of patients is sick and doctors and processing information process records in medical treatment process has played an important role. Long-termsince,the traditional medical records are paper records, are easy to tamper with the and difficult to save shortcomings. Current information has penetrated all walks of life, the paper also gradually began to be electronic medical records (EMR) replaced.Hospital information construction is our country "1025" during one of the emphases on the work, as the core of the electronic medical records construction will is the top priority. Electronic medical records to set the patient’s all kinds of information, its security is very important, so establish a safety feasible electronic medical records system specific safety is of great significance. This paper introduces the previous to the safety of electronic medical records, based on the existing technology puts forward a kind of relatively perfect electronic medical records authentication system responsibility, and the medical records of the document management, XML digital signature technology, XML key management knowledge to do the research.Electronic medical records include document security information integrity, not the content of the more modification and good secrecy. The safety of medical records including the integrity of the document, confidentiality and undeniable, etc. Modern password for the security of electronic medical records technology provides the technical support. Our country’s existing electronic medical records system is to pay attention to its management more attribute, the lack of electronic medical records of safety into consideration, this paper focuses on the safety technology in the electronic medical records XML application and realization.XML documents has good expansibility and strong structural characteristics, suitable for electronic medical records. In this article, the XML Schema mode library document to medical records for processing. Due to the XML Schema mode library of general that the different between hospital information exchange possible, effective solve the doctor patient encountered in the process of turn courtyard, consultation, etc. This paper gives the electronic sick system key module, and designed a detailed encryption,Signature, and declassification procedures. On this basis, combining with Eric Jui-n Lu "rules set" technology, puts forward a higher feasibility of electronic medical records multi-signature scheme, construct a perfect electronic medical records authentication system responsibility.This paper used XKMS and combining PKI management encryption and signature need the keys. Established based on Web Service XML key management regulations Service structure.To sum up, this paper use a restrict each other "rules set" technology established based on multiple signature of electronic medical records authentication system responsibility.
