Abstract

As the method of collecting and utilizing structured and unstructured data develops due to the influence of the Fourth Industrial Revolution, unwanted personal information data is also being collected and utilized, and hackers are attempting various attacks to steal information. As a result, the importance of information protection has increased, and various protection techniques have emerged, among which many studies have been conducted using decentralized techniques of blockchain and various algorithms to strengthen the security of biometric authentication techniques. This paper proposed a public blockchain biometric authentication system that allows users to protect their data in a safer biometric authentication method in the public blockchain and use it in the blockchain through signature with authenticated information.

4차 산업혁명의 영향으로 정형, 비정형 데이터를 수집 및 활용하는 방식이 발전됨에 따라 원치 않은 개인 정보 데이터도 수집되어 활용하고 있으며, 해커들은 정보탈취를 위해 다양한 공격을 시도하고 있다. 그럼에 따라 정보보호에 대한 중요성이 증가 되어 여러 보호 기법들이 등장하게 되었고 그 중 생체인증 기법의 보안성을 강화하기 위해 블록체인의 탈중앙화 기법과 다양한 알고리즘들을 활용한 연구가 많이 진행되었다. 본 논문에서는 분산 인증 시스템인 SMPC를 퍼블릭 블록체인 생체인증 시스템에 활용함으로써 사용자가 퍼블릭 블록체인 안에서 더욱 안전한 생체인증 방식으로 자신의 데이터를 보호할 수 있고 인증된 정보로 서명을 통해 블록체인 안에서 이용할 수 있도록 하는 퍼블릭 블록체인 생체인증 시스템을 제안하였다.
