An important component of SSI is a wallet that stores cryptographic keys and other identity data. Secure backup and recovery methods for data stored in such wallets are a crucial feature for its wide-scale adoption, however, such a feature is lacking or implemented casually in the existing SSI wallets. In this research, we propose a secure backup and storage of SSI wallets using a novel technology called Solid Pod. Solid Pod is an emerging technology that enables users to securely store data online. Towards this aim, we present the architecture, based on a threat model and requirement analysis, of the proposed approach. We also discuss its implementation details, outline a number of protocol flows highlighting different use-cases and analyse its security, advantages and limitations.11 Pagesen-USBlockchainHyper-ledger indyHyperledger ariesSelf-Sovereign Identity (SSI)Social linked dataSolid podSSI walletComputer networks--Security measures.Conference Proceeding10.1109/COMPSAC61105.2024.00149
