Abstract

With the improvement of the medical system, the universal access of wearable devices and people's greater concern about personal health, personnel health detection has received greater attention. However, existing personnel status detection faces the problem that existing models cannot get more accurate results by multiple types of data because the data is difficult to obtain across domains due to privacy issue. In this paper, we propose a vertical federated learning model for person status detection using multimodal data. Considering the varying compute capability of training devices and the different inference speed caused by modality complexity, a lightweight feature extraction sub-model is used, while ensuring data privacy and tolerating accuracy degradation. Also, we design a Fast and Secure (FS) module that effectively reduces the amount of data onto the network transmission process, the model's dependence on the network and the risk of data being intercepted by the third party. Experiment results demonstrate the feasibility of multimodal vertical federated learning and the accuracy is increased by 5.6 percentage points compared with unimodal. The FS module reduces the amount of network transmission information by 50% and 48.1% during model use and model training, respectively

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A multi-modal machine learning model uses homomorphic encryption to securely share data required for training machine learning models.

    “A multi-modal machine learning model is proposed to effectively solve the problem of data islands and uses homomorphic encryption to securely share data required for training machine learning models [36].”
  • HE is very effective for FL privacy preservation because most operations required by FL systems, such as aggregation, model updates, and gradient calculations, can be performed without accessing raw data.

    “This approach is very effective for FL privacy preservation as most of the operations required by the FL systems like aggregation, model updates, and gradient calculations can be performed without accessing the raw data [34,35,36,37,38].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
