Design of Wireless Blood Pressure Monitor and Its Data Encryption Method / 中国医疗器械杂志

A wireless blood pressure measurement system was designed to facilitate the measurement of the patient's blood pressure and to transmit the measured data safely and reliably. Through PDA, radio frequency identification technology (RFID) and bluetooth technology, the function of reading patients' information and statistics and analysis of blood pressure, heart rate data was realized. The IDEA and RSA joint algorithms were used to encrypt the patients' data and the key of the IDEA algorithm to ensure the security of the patient' data. The test results showed that the system had high accuracy of measurement data, safe and reliable transmission, and improved the nurses' work efficiency.

Design and implementation of a resident information input system based on the android platform / 国际生物医学工程杂志

ObjectiveAn input system was designed to solve the current problems of slow creation of electronic health record caused by the difficulty of resident information input.MethodsThe system,based on the Android platform,was designed to collect and save information by using PDA devices,and to send the information to the remote receiver over the wireless network with the hybrid encryption of DES and RSA.The receiver saved the information into the relational database after decryption.ResultsThe system saved acquisition time greatly compared to the traditional method.The transmission speed,security and reception rate of the system could well satisfy the requirements of information collection.ConclusionThe system provides a better way to solving the problems of heavy workload,low efficiency and high error rate in information collection,and will play an important role in practical life.

Privacy Act in Korea and Electronic Medical Record Protection / 대한의료정보학회지

With the emergence of networked computing and the Internet, this paper addresses the changed medical privacy environment, in which medical data protection now has to be reassessed. It is mainly based on the Korea situation as a country without an omnibus medical data protection law. It touches also on data security, as medical data privacy cannot be effectively protected without strict regimes for data security. The contemporary state of the medical records in Korea stood to gain from the growth of informatics and the spread of trans-institutions data flows. It is in this context that there appears to be a need to review the recent medical records protection acts which are already showing signs of this age both the public sector and private sector. Some recommendations will be adopted to establish baseline principles and goals and to provide guidance on the future work of the medical data privacy act. One of these, the protection of privacy on electronic medical records, recognizes the ubiquitous nature of digital computer and network technologies today. Medical information should be acquired, disclosed and used only in ways that respect an individual's privacy. It should not be improperly altered or destroyed. And medical information should be accurate, timely, complete and relevant to the purpose for which it is provided and used. And it upholds and protects medical data security. For example a right to encrypt personal information effectively, a right to fair treatment in key public infrastructures so that no person is unfairly excluded in a way that would prejudice that person's ability to protect their privacy, a right to human checking of adverse automated decisions and a right to understand such decisions, a right, going beyond the aspiration of the 'openness principle', of disclosure of the collections to which others will have access and which might affect the projection of the profile of the individual concerned.

Design of Integrated Result Query Service System in HIS Based on Secure Data-exchange / 医疗卫生装备

Objective To solve the conflict between data security and sharing in hospital so that patients can get their clinical data through result query service system.Methods Advanced secure data-exchange technology was used to realize network isolation.Integrated result query service system adopted the embedded system as hardware and the embedded LINUX operation system as software.Results Through LAN query module,internet query module and the secure data-exchange module,the design of HIS multimedia query system was realized.Conclusion Via the application of HIS integrated query platform,the design of the hospital secure data exchange is proved to be feasible,reliable and practical.

Protection of Sensitive Data in HIS by Using Oracle 10G R2 / 医疗卫生装备

Objective To backup data stored in Oracle database in No.1 Military Medical Project.Methods Oracle encryption features,such as encrypting table columns,encrypting Rman backupset,encrytpting datapump export data were utilized,to encrypt sensitive data stored in HIS of No.1 Military Medical Project.Results The encryption features effectively protected Oracle online data and backup data.Conclusion These methods are secure and feasible in practice.Optimum method can be selected to encrypt data in database according system security requirements.

Application of Network Isolation and Secure Data Exchange to HIS / 医疗卫生装备

Objective To apply the techniques of network isolation and secure data exchange network to hospital information system.Methods Network isolation and secure data exchange were used to do data exchange and synchronization between two networks.Results A LIS result query system was designed and realized based on this technology.Conclusion Secure data exchange in HIS can be realized effectively by using the techniques of network isolation and secure data exchange and it has good foreground in hospital information system.[Chinese Medical Equipment Journal,2008,29(2):45-47]
