Description

생체신호를 이용한 인증방법 및 그에 따른 건강관리시스템Authentication method using biosignal and health management system
본 발명은 대한민국 교육과학기술부 지원하에 과제번호 2012-013549에 의해 이루어진 것으로서, 상기 과제의 연구관리전문기관은 한국연구재단, 연구사업명은 "일반연구자지원사업(지역대학 우수 과학자)", 연구과제명은 "대규모의 다양한 PHD 운용을 위한 통합기기 관리시스템 개발", 주관기관은 계명대학교 산학협력단, 연구기간은 2012.05.01 ~ 2015.04.30이다.The present invention was made by the task number 2012-013549 under the auspices of the Ministry of Education, Science and Technology, the research management specialized organization of the project is the Korea Research Foundation, the research project name is "General Researcher Support Project (Local University Excellent Scientist)", "Development of integrated device management system for large-scale PHD operation", the host institution is Keimyung University Industry-Academic Cooperation Group, and the research period is 2012.05.01 ~ 2015.04.30.
본 발명은 건강관리시스템에 관한 것으로, 더욱 상세하게는 원격 건강관리를 위해 생체신호를 송수신하는 건강관리 시스템에서 사용자 인증 또는 데이터 송수신시에 PHD에서 측정한 생체신호를 이용함으로써 사용자 인증 또는 데이터 송수신에 대한 기밀성 및 무결성을 제공하는 생체신호를 이용한 인증방법 및 그에 따른 건강관리시스템에 관한 것이다.The present invention relates to a health care system, and more particularly, to a user authentication or data transmission and reception by using a biosignal measured in PHD during user authentication or data transmission and reception in a health care system for transmitting and receiving a biosignal for remote health care. The present invention relates to an authentication method using a biosignal that provides confidentiality and integrity for a health care system and a health care system.
최근 기술의 발달 및 건강 관리 의식의 대중화로 인하여, 원격으로 사용자의 생체신호를 측정하고, 이를 전송하여 모니터링하는 건강관리시스템에 대한 관심이 증대되고 있다. 아직 우리나라에서는 법률적인 뒷받침이 부족하여, 유비쿼터스 건강관리시스템이 활성화되고 있지 않으나, 유럽이나 미국에서는 이미 건강관리 시스템이 활성화되고 있다. 따라서 점증되는 고령화 추세에 대응하여, 우리나라에서도 곧 건강관리 시스템이 활성화될 것이다.Recently, due to the development of technology and popularization of health care consciousness, there is a growing interest in a health care system that measures a user's biometric signal remotely and transmits and monitors it. The legal support in Korea is still lacking, so the ubiquitous health care system is not activated, but the health care system is already active in Europe and the United States. Therefore, in response to the aging trend, the health care system will be activated in Korea soon.
상기 건강관리 시스템은 심전도 측정기(ECG monitor), 활동량계(Activity monitor), 산소포화도 측정기(Pulse oximeter), 혈압계(Blood pressure monitor) 및 혈당 측정기(Blood glucose meter) 등과 같이, 개인의 생체정보를 모니터링하기 간편한 개인의료기기(Personal Healthcare Device, PHD)들을 이용하여 측정한 개인 생체정보를 유무선 통신을 통하여 원격의 모니터링 서버에게 전달하고, 의료진이나 친척들이 생체신호를 체크하도록 하는 것이 일반적인 경우이다. 따라서 통상적으로 생체신호는 심전도, 활동/운동 정보, 산소포화도, 혈압 및 혈당 등을 일컫는다.The health care system monitors biometric information of an individual, such as an ECG monitor, an activity monitor, a pulse oximeter, a blood pressure monitor, and a blood glucose meter. It is common practice to transmit personal biometric information measured using easy-to-use personal healthcare devices (PHDs) to a remote monitoring server through wired / wireless communication, and to allow medical staff or relatives to check biosignals. Accordingly, the biosignal generally refers to an electrocardiogram, activity / exercise information, oxygen saturation, blood pressure, and blood sugar.
그러나, 사용자의 생체신호가 전송되는 과정에서 발생될 수 있는 개인 프라이버시 침해(제3자에 의한 생체신호 노출 혹은 조작 등)에 대한 연구는 아직 활성화되고 있지 않다. 또한 수신된 생체신호에 대한 인증(authentication), PHD 사용자 (혹은 송신자)에 대한 인증 문제도 중요한 이슈가 된다. However, research on personal privacy infringement (eg, exposure or manipulation of a biosignal by a third party) that may occur while a user's biosignal is transmitted has not been activated. Also, the issue of authentication of the received biosignal and authentication of the PHD user (or sender) are also important issues.
이에 종래의 인증방법에 대해 설명한다. The conventional authentication method will be described.
먼저, 퍼블릭 키(Public Key)를 이용한 인증방법이 있다. 상기 퍼블릭 키를 이용한 인증은 송신자가 자신의 비밀 키(private key)를 이용하여 메시지(M)를 암호화하여 송신하면, 수신자가 송신자의 퍼블릭 키(public key)를 이용하여 복호하여 인증하는 것이다. 이러한 퍼블릭 키 암호 방법으로는 RSA, ElGamal, Elliptic curve 암호 방법들이 대표적이다. First, there is an authentication method using a public key. In the authentication using the public key, when the sender encrypts and transmits the message M using its private key, the receiver decrypts and authenticates using the sender's public key. Such public key cryptography methods are RSA, ElGamal, and Elliptic curve cryptography methods.
그리고, 해쉬(Hash) 값을 이용한 인증방법이 있다. 이 해쉬 값을 이용한 인증 방법은 송신자가 메시지(M)의 해쉬 값을 구한 후, 메시지에 붙여서 송신하면, 수신자는 수신한 메시지(M)에 대한 해쉬 값을 구한 다음, 그 메시지와 함께 전송되어온 해쉬 값과 비교하고, 두 값이 같으면, 수신 메시지를 접수하면 되고, 틀릴 경우에는, 수신 메시지가 전송 도중에 내용이 바뀌었을 수 있으므로 파기한다. 대표적인 해쉬 값을 이용한 인증방법으로는 SHA 등이 있다.Then, there is an authentication method using a hash value. In this authentication method using the hash value, when the sender obtains the hash value of the message (M) and attaches it to the message, the receiver obtains the hash value for the received message (M), and then the hash transmitted with the message. If the two values are the same, the received message is accepted. If the value is wrong, the received message is discarded because its contents may have changed during transmission. Representative authentication methods using SHA include SHA.
그리고, MAC을 이용한 인증방법이 있다. 이 MAC(Message Authentication Code)을 이용한 인증방법은 해쉬 값을 이용한 방법과 대체로 같으나, MAC의 경우에는 키(key)가 필요하다.There is an authentication method using MAC. The authentication method using the MAC (Message Authentication Code) is generally the same as the method using the hash value, but in the case of MAC, a key is required.
그외에는 해쉬 값과 MAC을 모두 이용한 HMAC, CMAC, CCM, GCM 등이 있고, 송신자 및 메시지 내용 모두를 인증할 수 있는 전자서명(Digital Signature) 방법도 있으며 DSS(Digital Signature Standard)가 대표적이다.In addition, there are HMAC, CMAC, CCM, and GCM using both hash value and MAC. There is also a digital signature method that can authenticate both the sender and the contents of a message. DSS (Digital Signature Standard) is a typical example.
본 발명은 원격 건강관리를 위해 생체신호를 송수신하는 건강관리 시스템에서 사용자 인증 또는 데이터 송수신시에 PHD에서 측정한 생체신호를 이용함으로써 사용자 인증 또는 데이터 송수신에 대한 기밀성 및 무결성을 제공하는 생체신호를 이용한 인증방법 및 그에 따른 건강관리시스템을 제공하는 것을 그 목적으로 한다.The present invention uses a biosignal that provides confidentiality and integrity for user authentication or data transmission and reception by using a biosignal measured in the PHD during user authentication or data transmission and reception in a health care system for transmitting and receiving a biosignal for remote health care. The aim is to provide a certification method and a health care system accordingly.

<원격 건강관리 시스템의 구성><Configuration of Remote Health Care System>
상기한 본 발명의 바람직한 실시예에 따른 건강관리시스템의 구성을 도 1을 참조하여 상세히 설명한다. The configuration of a health care system according to a preferred embodiment of the present invention described above will be described in detail with reference to FIG. 1.
상기 건강관리시스템은 건강관리서버(100)와 사용자들 각각에게 배포된 제1 내지 제NPHD(Personal Healthcare Device)(2001~200N)으로 구성된다. The health care system is composed of a health care server 100 and first to NPHD (Personal Healthcare Device) 2001-200N distributed to each of the users.
상기 건강관리서버(100)는 원격에 위치하는 제1 내지 제NPHD(2001~200N)와 네트워크를 통해 연결되어 상기 제1 내지 제NPHD(2001~200N)를 통해 사용자들에게 원격 건강관리 서비스를 제공한다. The health care server 100 is connected to the first through the NPHD (2001 ~ 200N) located in the remote network through the first through the NPHD (2001 ~ 200N) to provide remote health care services to users do.
즉, 상기 건강관리서버(100)는 상기 제1 내지 제NPHD(2001~200N)로부터 사용자 인증정보를 제공받아 사용자 인증을 이행하고, 데이터를 수신받아 원격 건강관리 서비스를 제공한다. That is, the health care server 100 receives user authentication information from the first to NPHD (2001 to 200N), performs user authentication, and receives data to provide a remote health care service.
특히, 상기 건강관리서버(100)는 상기 제1 내지 제NPHD(2001~200N) 중 어느 하나로부터 사용자 ID와 비밀번호 등과 같은 사용자 인증정보가 제공되면, 해당 사용자에 대해 미리 수신받아 저장해두었던 생체정보들의 측정시각들 중 임의의 한 측정시각을 선택하여 그 시각정보를 해당 PHD로 전송하고, 그 PHD가 수신받은 시각정보에 대응되게 측정되어 저장된 생체정보를 독출하여 건강관리서버(100)로 전송하면, 건강관리서버(100)는 전송된 생체정보와 미리 저장되었던 생체정보를 대비하여 사용자 인증을 이행함과 아울러 인증결과를 해당 PHD로 통지한다. In particular, when the health care server 100 is provided with user authentication information such as a user ID and a password from any one of the first to the NPHD (2001 to 200N), the biometric information previously received and stored for the user If any one of the measurement times is selected and the time information is transmitted to the corresponding PHD, the PHD is measured to correspond to the received time information, and the stored biometric information is read and transmitted to the health care server 100, The health care server 100 performs user authentication in comparison with the transmitted biometric information and previously stored biometric information, and notifies the PHD of the authentication result.
또한, 상기 건강관리서버(100)는 상기 제1 내지 제NPHD(2001~200N) 중 어느 하나로부터 송신 메시지가 수신되면, 그 송신 메시지에 포함된 데이터와 해당 PHD로부터 수신받아 저장해둔 생체신호 중 최근 생체신호를 이용하여 해쉬값을 생성하고, 그 해쉬값과 상기 메시지에 포함된 해쉬값을 비교하여 메시지의 무결성을 검증한다. In addition, when the health care server 100 receives the transmission message from any one of the first to NPHD (2001 to 200N), the health care server 100 receives the latest data from the data included in the transmission message and the biosignal received and stored from the corresponding PHD.
