Abstract
A computer apparatus and computer-implemented apparatus for logging audio to an audio logger. Audio is transmitted from a source communication device. At least one receiving communication device receives the audio. The audio is logged to an audio logger, for example by the source communication device and the receiving communication device. A hash of the audio is computed and the hash of the audio and communication parameters related to the audio are stored in a blockchain.
