Abstract
At least one node in a distributed hash tree verification infrastructure is augmented with an identifier of an entity in a registration path. A data signature, which includes parameters for recomputation of a verifying value, and which is associated with a digital input record, will therefore also include data that identifies at least one entity in the hash tree path used for its initial registration in the infrastructure. An uppermost value of the hash tree verification infrastructure is entered as, or as part of, a transaction in a blockchain.
