Decentralized identity prevents credential forgery effectively by using cryptographic techniques such as digital signatures and blockchain technology. Credentials are issued and signed by trusted entities, making them tamper-evident. Any alteration to the credential would invalidate the signature, alerting verifiers to potential forgery. Additionally, decentralized ledgers provide a transparent and immutable record of credential issuance and revocation, further enhancing security and preventing unauthorized duplication or modification.
