초록
본 논문에서는 중앙화된 데이터 저장소에 신체치수와 같은 텍스트 형식의 개인의 민감한 개인정보를 저장하지 않고, SoulBound Token에 데이터를 저장하는 방식으로 정보 보안을 강화하는 방법을 제안한다. InterPlanetary File System 방식으로 민감한 정보를 저장하고, Content Identifier을 받아 SBT에 연동하였기에 데이터베이스에 직접적으로 저장하지 않는다. SBT 열람 권한은 사전에 승인된 계좌에서만 접근이 가능하도록 제한하여 민감한 정보를 다루는 스타트업에서 안전하게 활용하는 방법으로 제안된다. 실험을 통해 접근이 제한된 계좌에서 접근이 불가능하다는 점을 확인하였으며 소유자가 접근 권한을 부여 및 회수할 수 있도록 진행하였다. 또한 본 논문은 SBT 발행 시 고려해야 할 다양한 Layer2 Solution의 장단점을 요약하고, Layer2 Solution을 활용하여 거래처리 속도 증가 및 메인넷 대비 1/4300 수준의 가스비로 SBT를 생성하는 방식을 제안한다.
Abstract
This paper proposes a method to enhance information security by storing data in SoulBound Token instead of storing sensitive personal information, such as body measurements, in centralized data storage systems in text format. Sensitive information is stored using the InterPlanetary File System method, and the corresponding Content Identifier is linked to the SBT, avoiding direct storage in a database. Access to the SBT is restricted to pre-approved accounts, allowing startups handling sensitive information to securely use the data. Through experiments, it was confirmed that access was impossible from unauthorized accounts, and the owner was able to grant and revoke access permissions as needed. Furthermore, the paper summarizes the advantages and disadvantages of various Layer 2 solutions to consider when issuing SBTs, proposing a method to enhance transaction processing speed and generate SBTs at a gas fee rate approximately 1/4300th of the mainnet.
