1 Functions

The Health Front End (AIH-HFE) AIM enables the End User to

  1. Register with the Health Back End.
  2. Use Health Devices to collect various types of Health Data.
  3. Provide a Model Licence to each Health Data collected.
  4. Request the Health Front End to Process AIH Data.
  5. Send AIH Data to the Health Back End.
  6. Request The Back End to Process AIH Data.

The Health Front End

  1. Stores AIH Data as combination of Model Licence and Health Data.
  2. Processes AIH Data.
  3. Adds Anomaly and Risk Alerting (ARA) Data, if present, to each AIH Data.
  4. Receives requests for trained NN Models from Health Back End.
  5. Sends its trained NN Models to the Health Back End for Federated Learning.

The End User owning the Front End is not bound by the Model Licence.

4.2 Operation

The AIH-HFE AIM operation develops as follows

  1. End User registers with HFE and HBE.
  2. End User acquire Health Data with a Health Device.
  3. End User attaches Model Licence to Health Data.
  4. Model Licencing stores AIH Data (including Health Data and Model Licence).
  5. End User process AIH Data locally.
  6. End User stores AIH Data to HFE.
  7. End User process AIH Data remotely.
  8. HFE receives Federated Learn request.
  9. HFE sends NN Model to HBE.
