Two-Fold Digital Credential Verification and Signing Methods
Summary
USPTO published patent application US20260100851A1 disclosing methods and systems for issuing certificate-type digital credentials and electronically signing documents. The invention requires two-fold verification comprising credential validity checks (proof, expiration, revocation) plus verification that a trusted issuer exists within a parent-child relationship. Both credential types can be organized in a digital identity hierarchy using distributed ledger technology.
What changed
USPTO published patent application US20260100851A1 for methods and systems related to digital credential verification and electronic signing. The invention discloses a two-fold verification process requiring both that a digital credential is valid (including proof validity, expiration date, and revocation status) and that at least one linked issuer is trusted according to a parent-child relationship structure. The system supports both certificate-type and non-certificate digital credentials organized in a hierarchical digital identity framework.
Affected parties include technology companies developing digital identity systems, blockchain-based credential platforms, and electronic signature solutions. The patent's distributed ledger implementation claims may be relevant to companies building self-sovereign identity systems, verifiable credential infrastructures, or digital signature platforms requiring robust authentication mechanisms.

Abstract
Disclosed in the present invention include methods and systems for issuing a certificate-type credential and electronically signing a document. Both applications require to verify if a digital credential of a prover or a signer is authenticated. Authentication of the digital credential requires a two-fold verification that the digital credential is verified to be valid and one of at least one issuer linked to the digital credential according to a parent-child relationship is verified to be trusted. To verify that the digital credential is valid, validity of a proof, expiration date, and revocation information associated with the digital credential should all be verified to be valid. The two-fold verification secures more for digital credential verification. Non-certificate type digital credentials and certificate-type digital credential can be organized in a digital identity hierarchy allowing ownership of multiple digital credentials to one entity implemented with distributed ledger technology effectively avoiding single point of failure.
