The Research And Application Of Handwritten Singnature Verification Technology In HIMS

Handwritten signature authentication technology is a new kind of identity authentication technology implicating in hospital system, it can effectively shorten the check-up of the queue time, improve the efficiency of doctor visits, provide more quick and convenient services for patients. Handwritten signature authentication technology can effectively prevent forgery signatures, provides convenience for hospital work. Using this technology can further realize hospital system of office automation and strengthen the protection of patient information and privacy. At the same time the implementation of the application can save money for hospital, not for medical personnel to use electronic signature update key valid signature date. It does not need pay a larger certificate renewal fees to the CA certification company. In respect of knowledge that need to be patient or the family book, can also be set up in the electronic medical record system, after being signed by the patients directly stored in the system, it can promote the development of the hospital the paperless office. And effectively record the signature of the doctors. To prevent the occurrence of medical accident, the doctor changes the medical records, patients tear the paper chart file records, to make responsible for doctors and patients.Aiming at the demand of the hospital information management system, firstly introduces the present situation of the hospital information system management, put forward the B/S structure is adopted to improve the hospital information management system development ideas, to solve the information authentication difficulties exist in the traditional hospital information system, medical liability is difficult to determine. Hospital information management system based on the technology of handwritten signature authentication, in. NET development platform, SQL Server as a tool for the development of each function module in the system. The use of system users are doctors, nurses, patients and medical support staff, each user has different permissions, the system administrator has the maximum privilege of the whole system, can realize to all user rights allocation. Only the user input the correct user name, password and permission to enter the system, and only after completing the handwritten signature authentication to the operations. In this paper, the main research contents are as follows:Firstly, of the hospital information management system development background, present situation and the related technology are introduced.Secondly, writing signature certification of hospital information system the player in the investigation and analysis of the needs of different users and use case diagram in the form of each of the modules in the hospital information system.Thirdly, the principle of system development and architecture are given, on the main functional modules in the system design, and completed the design of the database in the system.Fourthly, to complete the landing system interface design, interface and the corresponding certification rivals to write signature authentication technology has carried on the development of hospital information system function, get a suitable for hospital orders management, management of electronic medical records and test results management software system.Test results show that the design of information system can meet the demand of the use of all users in the hospital, has simple operation, high operating stability characteristics. The application of hospital information system based on handwritten signature can fundamentally solve the hospital can’t shall be investigated in liability, data will not be able to guarantee the authenticity, greatly improve the management of the affairs of the hospital and quality.
