ABO is a blood donation application. It helps donors and transfusers to interact directly and anonymously via the app. Blood donation is one of the most important issues that threaten people's lives severely because there is no substitute for blood. To make matters worse, the national blood donation rate has been decreasing and the supply is unstable. To solve this problem, we designed a one-to-many matching system based on anonymity. People could see transfusers’ situations and whether their blood is delivered without information leakage. This can make people feel proud and also manage their health and donation certificates on mobile
