We recommend to consider 5 ways to make sensitive data safe:
1. Permissioned Blockchain: One option for decentralized ID management is to store the data on a permissioned blockchain, where only authorized parties have access to the data. This ensures that the data is secure and not stored on open blockchains.
2. Encryption: Another option is to use encryption techniques to secure the ID data. This can include using public-key cryptography, hash functions, and other encryption methods to protect the data from unauthorized access.
3. Multi-factor Authentication: Decentralized ID management systems can also use multi-factor authentication to ensure that only authorized users have access to the ID data. This can include using biometric authentication, SMS verification, or other methods to verify the user's identity.
4. Distributed Ledger Technology: Another option is to use distributed ledger technology to store the ID data in a secure and decentralized manner. This can include using a private blockchain or other distributed ledger technologies to ensure that the data is secure and not stored on open blockchains.
5. Zero-knowledge Proofs: Decentralized ID management systems can also use zero-knowledge proofs to ensure that the user's identity is verified without revealing any sensitive information. This can help to protect the user's privacy while still ensuring that their identity is verified.
