SYSTEM AND METHOD FOR BLOCKCHAIN-BASED EMPLOYMENT VERIFICATION

NºPublicación: US2023028681A1 26/01/2023

Solicitante:

DISH WIRELESS LLC [US]

Resumen de: US2023028681A1

Techniques are described for receiving an online request to verify an asset, e.g., a line-item from an online profile. The technique determines a verifying entity, such as an educational institution, that has authority to verify the line-item, e.g., an earned certificate, and sends a request to such verifying entity to do so. The asset is added to and verified on the distributed ledger or is verified before adding to the distributed ledger. A verification indicator is coupled to the asset, signaling that the asset has been verified once and need not be verified again. A notification that the asset is verified is transmitted to interested parties. The verification may be at a level, such as a one day verification of a negative drug test. The verifications are searchable on the distributed ledger, e.g., an employer may query for verified assets that match job-related requirements.
