Description

헌혈 관리 방법 및 시스템Blood donation management method and system
본 발명은 헌혈 관리 방법 및 시스템에 관한 것으로서, 혈액 정보와 개인 정보를 포함하는 헌혈 정보의 전송시 인증과 서명을 통하여 투명한 관리가 가능하고 헌혈 정보의 저장시 분산 저장하여 투명하고 안전한 관리를 가능하도록 하는 헌혈 관리 방법 및 시스템에 관한 것이다.The present invention relates to a blood donation management method and system, in which transparent management is possible through authentication and signature when transmitting blood donation information including blood information and personal information, and transparent and safe management is possible by distributed storage when storing blood donation information. It relates to a blood donation management method and system.
출산율의 하락과 고령화의 증가와 함께 인구가 감소하고, 헌혈 인구의 70% 이상을 차지하는 10 ~ 20대의 헌혈 인구 비율도 급작스럽게 감소하고 있으며, 혈액을 대체하기 위한 인공 혈액은 면역 체계와 관련하여 위험성이 존재하고 있는바, 혈액의 가치는 더욱 더 상승하게 된다.Along with the fall of the fertility rate and the increase of aging population, the population is decreasing, and the proportion of the blood donor population in their 10s to 20s, which accounts for more than 70% of the blood donation population, is also rapidly decreasing. As this exists, the value of blood increases more and more.
이미 많은 국가에서 혈액 부족의 문제점을 인식하고 있으나 혈액 공급자의 부족과 수요자의 증가가 더욱 더 가속화될 것으로 보이고, 혈액 부족 사태가 시작되는 순간 많은 것들이 우리의 소중한 삶을 훼손할 수 있으며, 혈액은 오직 인간에서만 얻을 수 있는 고유 자원으로서 혈액의 가치와 가격의 상승은 가까운 미래에 폭등할 것으로 보인다.Although many countries are already aware of the problem of blood shortage, the shortage of blood providers and the increase in the number of consumers are expected to accelerate more and more, and as soon as the blood shortage begins, many things can damage our precious lives. The rise in the value and price of blood as a unique resource that can only be obtained from humans is expected to surge in the near future.
혈액 부족 사태가 전망됨에도 불구하고 단체 헌혈 중심의 후진적 채혈 관행이 고수되고 있고 자발적인 헌혈이 부족하여 혈액 부족 사태가 개선되기 어렵고, 채혈 단계에서부터 혈액의 안전성을 확보하는데 불안감이 확산되고 있다.Despite the prospect of a blood shortage, the backward blood collection practice centered on group blood donation has been adhered to, and the lack of voluntary blood donation makes it difficult to improve the blood shortage situation, and anxiety is spreading in securing the safety of blood from the blood collection stage.
또한 종래의 헌혈 관리 시스템에서는 헌혈자의 혈액 정보와 개인 정보가 중앙집중적으로 저장되고 투명하게 관리되지 아니하여 혈액 관리에 사고가 발생하는 경우 헌혈 관리 시스템에 대한 신뢰가 저하되어 혈액 부족 사태를 더욱 더 악화시킬 수 있다. In addition, in the conventional blood donation management system, blood donor information and personal information are centrally stored and not managed transparently, so if an accident occurs in blood management, trust in the blood donation management system decreases, further exacerbating the blood shortage situation. I can make it.
또한 헌혈자의 혈액 정보와 개인 정보, 헌혈 증서에 대해서 투명하게 관리되지 못하는 경우 불법적인 혈액 거래가 발생할 수 있고, 이러한 불법적인 혈액 거래는 자발적인 헌혈 참여를 저해하여 혈액 부족 사태를 더욱 더 악화시킬 수 있다. In addition, if the donor's blood information, personal information, and blood donation certificate are not transparently managed, illegal blood transactions may occur, and such illegal blood transactions may hinder voluntary blood donation participation, further exacerbating blood shortages.
등록특허공보 제10-0461534호는 헌혈자들에게 헌혈 포인트를 적립하고 그 적립된 포인트를 편리하게 이용하도록 함으로써, 일반인들의 자발적인 헌혈 참여를 유도할 수 있는 헌혈 관리 시스템에 관한 것으로서, 개인들의 헌혈 참여를 자발적으로 유도할 수 있는 시스템을 개발하되 기존의 밴(VAN)망을 활용함으로서 시스템 구축을 위한 시간적/물적/인적 비용을 최소화할 수 있는 헌혈 관리 시스템을 제공하고, 헌혈자 정보를 DB화하여 체계적으로 헌혈자 관리가 이루어지도록 하되 기존의 밴(VAN)망을 활용함으로서 시스템 구축을 위한 시간적/물적/인적 비용을 최소화할 수 있도록 하고 있으나, 헌혈자 정보를 중앙집중적으로 관리하는 것으로 보이고 헌혈자 정보와 헌혈 증서의 투명한 관리가 어렵다는 문제점이 있다.Registered Patent Publication No. 10-0461534 relates to a blood donation management system that can induce voluntary blood donation participation by the general public by allowing donors to accumulate blood donation points and use the accumulated points conveniently. Develop a system that can voluntarily induce, but provides a blood donation management system that can minimize the time/material/human cost for system construction by utilizing the existing VAN network, and systematically converts blood donor information into a DB. It is possible to minimize the time/material/human cost for system construction by using the existing VAN network, but it seems that the donor information is managed centrally, and the donor information and the blood donation certificate are managed centrally. There is a problem that transparent management is difficult.
공개특허공보 제10-2007-0023942호는 디지털 헌혈 관리 시스템에 관한 것으로서 고객이 헌혈하는 경우 헌혈증 번호를 고객 단말의 단문메시지(SMS)로 전송 받으며, 이를 바탕으로 고객이 원하는 기부 단체를 선택하여 콜-백(CALL-BACK) SMS 방식으로 쉽게 기부할 수 있도록 하기 위한 것이나, 헌혈 정보 및 헌혈 증서의 관리와 사용이 투명하고 안전하게 관리되기 어렵다는 문제점이 있다.Korean Patent Publication No. 10-2007-0023942 relates to a digital blood donation management system. When a customer donates blood, a blood donation certificate number is transmitted as a short message (SMS) on the customer terminal. Based on this, the customer selects a donation organization and calls -CALL-BACK This is to make donations easily by SMS method, but there is a problem that the management and use of blood donation information and blood donation certificates are difficult to manage transparently and safely.

또한 헌혈자(30)가 수신자에게 BD 증서(320)를 직접 전달하는 트랜잭션이 가능하도록 하여 이러한 트랜잭션이 블록으로 저장되므로 투명한 관리가 가능할 수 있지만, 이러한 트랜잭션을 취합하여 관리하는데 비용이 증가할 수 있으므로, 헌혈자(30)가 BD 증서(320)를 기부하는 경우에 항상 적십자사(10)가 중간에 경유되도록 함으로써 관리 비용을 저감할 수 있게 된다.In addition, since a transaction in which the blood donor 30 directly delivers the BD certificate 320 to the recipient is possible, such transactions are stored as blocks, transparent management may be possible, but the cost to collect and manage these transactions may increase. When the blood donor 30 donates the BD certificate 320, it is possible to reduce the management cost by always passing the Red Cross 10 in the middle.
또한 상기 BD 증서(320)는 소정의 조건을 생성 조건으로 하는 프로그램 코드로 작성되어 블록에 미리 저장될 수 있고, 상기 소정의 조건은 헌혈 정보의 입력과 헌혈자(30)의 헌혈 이후 헌혈 기관(20)으로부터의 승인에 의하여 자동으로 생성되어 헌혈자(30)의 공개키를 기반으로 하는 주소를 갖는 BD 지갑(300)으로 전송될 수 있다.In addition, the BD certificate 320 may be written in a program code with a condition for generating a predetermined condition and stored in advance in a block, and the predetermined condition is the blood donation organ 20 after input of blood donation information and blood donation by the donor 30. ) Can be automatically generated by approval from the donor and transmitted to the BD wallet 300 having an address based on the public key of the blood donor 30.
