Abstract
The disclosed computer-implemented method for authenticating digital media content may include (i) receiving digital media content that has been captured by a capturing device and digitally signed through a cryptoprocessor embedded within the capturing device to provide an assurance of authenticity regarding how the capturing device captured the digital media content, and (ii) encoding an identifier of the received digital media content and a digital signature to an encrypted distributed ledger, the digital signature including at least one of a digital signature of the digital media content by the capturing device or a digital signature of the digital media content by an entity encoding the received digital media content such that the encoding becomes available for subsequent verification through the encrypted distributed ledger. Various other methods, systems, and computer-readable media are also disclosed.
