Edge computing-oriented federated learning indoor positioning privacy protection method

ActiveCN111866869AReal-time indoor positioning serviceSecure Indoor Positioning ServiceTransmissionSecurity arrangementEdge computingPrivacy protection
The invention provides an edge computing-oriented federated learning indoor positioning privacy protection method. The method is based on federated learning and differential privacy protection technologies. According to the method, credible federation training of an indoor positioning model is carried out in an edge computing environment; in the training process, all participating users do not share training data, distributed training and credible aggregation of the indoor positioning model are carried out only by sharing positioning model parameters, meanwhile, the model parameters are updated in an end-cloud cooperation iteration mode, so that the indoor positioning model is continuously optimized, and privacy protection and cooperative benefits of multi-user positioning model training are achieved. Experimental results show that compared with a traditional centralized model training method and a federated learning-based model training method, the method provided by the invention notonly can provide proven privacy protection, but also ensures the positioning effect of the model under the condition of increasing extremely little calculation overhead.
