Electronic Medical Record Based On Xml Data Security Mechanism Research

With the development of computer information technology and medical technology, medical electronic technology has become a trend. Electronic system gradually enable the hospital to be digital information and paperless. In this environment, it can save the resources and also improves the operational efficiency of hospital itself, provides a good opportunity for the rapid, standard development of the medical cause. In china the electronic medical stated late, but develops faster on the help of its own and foreign experience. Now, the popularity of electronic information system makes the doctors and nurses increasingly depend on the electronic information system. The electronic medical information system has assumed the hospital a large part of the business operation, it mainly concludes medical data and management data. In the hospital system, management data is auxiliary information, and the core business is medical business, so the medical information is the core data. Medical business data mainly relies on the electronic medical records. And the electronic medical records note the entire medical process of the patient which involves treatment, medical technology test, hospitalization and other major core medical business. The data generated by those businesses are particular important data in the hospital. Also with the development of the information technology and people’s awareness of their own privacy protection, data security of the electronic medical records has increasing been more important.The electronic records contain the complex structure and contents, both structured information and unstructured information text. In recent years, with the development of telemedicine, people have the higher requirement to the share the medical data, but now the medical records we used mainly cover local part of the record. In order to get the interest, some hospitals do the regional restrictions, so the medical data’s sharing during different are is very poor. Electronic medical record notes that the patient’s entire health statues and reflects the patient’s privacy. It can cause patient’s privacy illegal disclosure. The electronic medical records also involves legal disputes, it can be the legal evidence to the medial dispute. So the security of the electronic medical record is very important.The paper involves follow management theory, such as business process reengineering management theory, information sharing theory and public crisis theory. The paper uses the XML technology to achieve the electronic medical record data safety. First, based on the model of three factors, the paper analyzes electronic medical business process analysis. Then, based on the UML model and the need medical behaviors, the paper designs the medical data structure. Then, doing the data security for electronic medical records, the paper uses the data decomposition model and confidentiality, integrity non repudiation requirements model to analyze the electronic medical data security requirements in the electronic medical record. Finally, do the achievement of the whole electronic medical record.Therefore, a scientific and effective medical record implementation provides the practical significance to achieve the data security and electronic medical information system development.
