System and method of verifying electronic signature of electronic medical record in medical information system

Abstract

The invention provides a system and a method of verifying an electronic signature of an electronic medical record in a medical information system. The method comprises the following steps of receiving the electronic medical record which is in an XML format and established by a doctor from a client; associating the electronic medical record after read-only locking with the electronic signature of a verifier and sending the electronic medical record to the client of the verifier based on the information of the verifier in the electronic signature; obtaining modification data of the electronic medical record and performing encrypted conversion on the modification data; cancelling the read-only locking for the electronic medical record and replacing the corresponding original data in the electronic medical record with the encrypted modification data; performing read-only locking on the modified electronic medical record; generating a formal electronic record; and updating the electronic signature of the verifier and associating the electronic signature with the formal electronic medical record. Through implementation of the system and the method of verifying the electronic signature of the electronic medical record in the medical information system, information security of the electronic medical record in the signature verification process can be improved, accurate modification of the electronic medical record is ensured, and a medical accident is prevented.

Description

technical field [0001] The invention relates to the field of medical informatization, in particular to a system and method for reviewing electronic signatures of electronic medical records in a medical informatization system. Background technique [0002] Medical records are the original records of patients in the whole process of diagnosis and treatment in the hospital. With the hospital computer management network, electronic medical records (EMR, Electronic Medical Record) came into being. As a product of scientific and technological progress, electronic medical records are more and more widely used in medical systems because of their advantages such as convenient recording and easy storage. [0003] However, in the existing electronic medical record system, when the content in the electronic medical record is signed, the electronic signature is not used for encryption processing, which reduces the information security of the electronic medical record and will lead to th...
