This study aims to present ways to enhance the stabilization of electronic medical records, ensure the commitment to filling in information of the medical record and improve the overall quality Electronic Medical Record(EMR) information. For that purpose, the present state of the incomplete record rate and the doctor's satisfaction in Electronic Medical Record(EMR) have been surveyed by comparing and analyzing Paper-based Medical Record(PMR) and Electronic Medical Record(EMR). The survey was conducted on 31 doctors in charge of EMR system and each PMR and EMR inpatients were collected for a period of 5 months and analyzed. The results showed that the doctor's satisfaction level was higher for EMR, and the rate of incomplete record appeared to be lower in EMR in departments of both internal and external medicine. In this context, it can be said that the higher efficiency of EMR helped accomplish the increase in commitment to completing medical record information and improve the quality of the data.

The rapid development and distribution of information communication industry facilitates the changes of hospital administration, introducing EMR(Electronic Medical Record) instead of paper-based medical record in the medical field. The developed countries such as U.S. have established EMR system after in the middle of 1970s because the primary advantages of EMR is to store and handle vast amounts of records efficiently and increase the quality of health care. Most of health organizations in Korea also apply medical record system to their administration. As the result, they have accomplished a scientific administration system through the use of medical record to handle a variety of patient's information including patient's confidentiality and privacy such as family history, social status, income level, and so on. However, access to and the misuse of EMR causes illegal infringement of patient's information and finally it becomes a very serious medical issue. Potential leakage and misuse of records may seriously infringe patient's privacy rights. In this respect, the related agencies in the public and private sector have been making efforts to prevent patient's records leakages. Especially, the revision bill of Medical Law in 2002 establishes the ways on the security and standards of electronic records. However, it does not provide the proper guidelines which is applied to the rapid changes of the medical environment. One of the most priorities in the hospital administration is the production and maintenance of an accurate medical records fulfilled by medical recorders. Therefore, it is very important for health care providers to hire ethical-based medical recorders. But, unfortunately most of hospitals overlook the importance of their roles. All parts including government, physician and patient must have more concerns on the problems related to EMR. Therefore, this study aims to propose the proper ways to resolve the problems coming from EMR.

In the system of ciphertext policy attribute-based encryption (CP-ABE), only when the attributes of data user meets the access structure established by the encrypter, the data user can perform decryption operation. So CP-ABE has been widely used in personal health record system (PHR). However, the problem of key abuse consists in the CP-ABE system. The semi-trusted authority or the authorized user to access the system may disclose the key because of personal interests, resulting in illegal users accessing the system. Consequently, aiming at two kinds of existing key abuse problems: (1) semi-trusted authority redistributes keys to unauthorized users, (2) authorized users disclose keys to unauthorized users, we put forward a CP-ABE scheme that has authority accountability, user traceability and supports arbitrary monotonous access structures. Specifically, we employ an auditor to make a fair ruling on the malicious behavior of users. Besides, to solve the problem of user leaving from the system, we use an indirect revocation method based on trust tree to implement user revocation. Compared with other existing schemes, we found that our solution achieved user revocation at an acceptable time cost. In addition, our scheme is proved to be fully secure in the standard model.

EMR(전자의무기록)이란 일반적으로 진료정보를 서면이 아닌 데이터 저장장치에 저장하는 것을 말한다. 이러한 EMR은 서면작성 시 문제점이던 서류보관, 배열, 공간확보등의 문제를 해결할 수 있고, 고객에 대한 다량의 정보를 이용하여 맞춤형 진료를 가능하게 하여 병원측에는 관리비용의 감소 및 업무 효율성 증대를 가져온다. 또한 고객의 입장에서는 양질의 의료서비스를 제공받을 수 있다. 이러한 장점 때문에 1990년대 이후 각 병원 및 의원에서 EMR이 급속도로 도입되며 현재 활용되고 있다. 하지만, 현재 사용중인 건강검진 시스템의 경우 EMR과 별도로 건강검진에 사용되는 서식지를 서면으로 작성하여 보관하고 있다. 서면으로 보관하는 이유는 여러가지가 있을 수 있으나, 병원에서 사용중인 EMR은 진료기록만을, 건강검진 시스템은 건강검진과 관련된 로직만을 수행하는 각각의 단위프로그램(unit program)으로 구성되어 있다. 이러한 이유로 건강검진 시스템에서 서면보관이 불가피 하였던 것으로 판단되며 이를 해소하기 위해 건강검진시스템에 EMR 기능을 적용하여 보다 효율적인 건강검진 솔루션 운영이 가능하게 될 것으로 기대한다.

The Electronic Medical Record (EMR) is a valuable source of medical data intelligence in e-health systems. The watermarking techniques have been used to authenticate the owner and protect the EMR from illegal copying. The existing distributive strategies, successfully operated to secure the EMR, are found to be inadequate. Blockchain technology, mainly, is employed by a sharing database that allows the digital crypto-currency. It rapidly leads to the magnified expectations acme. In this excitement, the use of consortium adopting the technology based on Blockchain, in the EMR structure, is found improving. This type of consortium adds an immutable share with a translucent record of the entire business and it is accomplished with responsibility, along with faith and transparency. The combination of watermarking and Blockchain technology provides a singular chance to promote a secured, trustworthy electronic documents administration to share with the e-records system. The authors, in this article, present their views on consortium Blockchain technology which is incorporated in the EMR system. The ledger, used for the distribution of the block structure, has team healthcare models based on dissimilar multiple image watermarking techniques.

Medical environments incorporate complex and integrated data networks to transfer vast amounts of patient information, such as images, waveforms, and other digital data. To assure interoperability of images, waveforms and patient data, health level seven(HL7) was developed as an international standard to facilitate the communication and storage of medical data. We also adopted medical waveform description format encoding rule(MFER) standard for encoding waveform biosignal such as ECG, EEG and so on. And, the study converted a broad domain of clinical data on patients, including MFER, into a HL7 message, and saved them in a clinical database in hospital. According to results obtained in the test environment, it was possible to acquire the same HL7 message and biosignal data as ones acquired during transmission. Through this study, we might conclude that the proposed system can be a promising model for electronic medical record system in u-healthcare environment.
