An Open Sharing Method for Digital Heritage Assets Based on Self-Sovereign Identity Technology

Abstract

To address the issues of ownership and trustworthiness that are prevalent in the flow of Digital Heritage Assets(DHAs), this study proposes a method for DHA open sharing based on self-sovereign identity technology. Through decentralized identifier technology and blockchain technology, the trusted identity registration and verification of a participating subject are realized; through verifiable credential technology, the registration and flow of a DHA are realized; through verifiable credential technology and digital signature technology, the access and trustworthiness verification of a DHA are realized. This method can guarantee the trustworthiness of the identity of a participating subject, maintain the ownership attribution and trustworthiness of a DHA in the flow, and ultimately promote the scope and efficiency of DHA open sharing.
