XML기반의 처방전 보안 시스템 설계 및 구현

Abstract

XML is attracting expectation by raising the Internet technical level that scattered after HTML with metalanguage providing a format to describe structured data. Because this is the one of the next generation EDI study that is going to solve a problem of various traditional EDI systems as active application development applying performed XML technology to an EDI message. The purpose of DTD is a discrimination of meaning about document underwear data, the other one is a effectiveness inspection of a document as a file having MeTa contents to express XML. Therefore, a security policy suitable for XML own security is asked on DTD. However, a effective policy for a DTD security is not offered yet because for one XML document, it must be written solely one DTD with a base, also the lack of expansibility of an element declaration drops. As for the history of transaction, a medical insurance association and a Korean communication originated jointly through construction of a medical care section EDI system for a consultation fee demand and payment through a medical insurance EDI showing an example business in the former between organizations of the hospital in case of domestic medical care field in May for 1994 years. A cost to have obeyed a paper prescription publication and management occurs in entrance of a medical care organ by execution of medicine division of labor in July for 2000 years, and pay personnel expenses an increasing rate. with division of work a prescription publication, medical examination record and consultation fee demand materials drawing up if I published the paper prescription which became a notes. A re-input and dual work of health insurance demand examination materials drawing up of prescription materials arise in a drugstore, waste of time resources. several on expansion the time that a medical care user must visit a medical care organ and a drugstore at the same time, and reach compounding of medicines in prescription. Also, possibility for health to rather turn worse has a compounding of medicines delay and a back giving up compounding of medicines if a prescription is lost. Also, a wrong compounding of medicines by misreading of a pharmacist by a notes prescription of a doctor or a damaged prescription, and health of a patient can become a problem. Therefore, I propose a prescription transmission system based on XML in this paper, and it is not to attach a former signature to only a XML document for encoding of XML/EDI, and it is construction, one with the prescription transmission system which is safer with what use a way to attach a digital signature to DTD. I defined sub element to manage information prescription DTD defined prescription information, patient information, medical care organ information, prescription details information, compounding of medicines details information element according to for each a component of a prescription I went along, and to have looked up, and to have obeyed information transmission at he low rank. I read a DTD file for safe prescription transmission, and I do element or property, the entity which I do it, and is extracted here, and Pasing is saved in a table while being a field. If Pasing is finished, I read and lift a hash table and carry out message a digest. I compose it with an early private key and create a digital signature.
