Abstract
A recording of a call is authenticated using a distributed transaction ledger. A call between two or more participants is recorded to generate a call recording. A record of the call recording is stored within a distributed transaction ledger. At a later time, such as in response to an access request for auditing or an authentication request, the call recording is authenticated based on information associated with the record within the distributed transaction ledger. An indication of the authentication is then output, such as for further processing or display.
