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.
Claims15
A computer-implemented method for logging played audio to an audio logger, the method comprising:
- transmitting audio from a source communication device;
- receiving the audio at a receiving communication device;
- logging played audio to an audio logger via a computer apparatus at the receiving communication device, wherein the played audio comprises the audio that was played through a speaker at the receiving communication device;
- computing a hash of the audio and communication parameters related to the audio;
- and
- storing the hash in a blockchain.
A computer apparatus for auditing group communications, the computer apparatus comprising:
- a communication interface;
- one or more processors;
- and
- a memory having executable code stored therein, wherein the executable code, when executed by the one or more processors, causes the one or more processors to:
- determine members of a Push-To-Talk (PTT) group;
- for each of the members of the PTT group, retrieve a record from a blockchain, the record including a hash of audio and communication parameters related to the record;
- and
- audit each record by running data analytics on at least one of the hash of the audio, the communication parameters related to the record, or the record from a blockchain.
