Platform for forgetting and verifying data in federal learning

The invention discloses a platform for forgetting and verifying data in federal learning. The platform comprises a federal forgetting module, a federal forgetting marking module, a forgetting checking module and an actually deployable protocol used for connecting the three modules. The federal forgetting marking module is used for marking forgotten users based on local data subsets; the forgetting checking module defines an index-forgetting degree suitable for evaluating the forgetting condition, the forgetting condition is numeralized, and the lower forgetting degree represents a better forgetting effect; the protocol stipulates time nodes of forgetting, marking and checking, executors of forgetting, marking and checking, and processes of forgetting, marking and checking, so that the central server executes forgetting and forgetting users check whether the forgetting users are forgotten or not. According to the platform provided by the invention, forgetting, marking and checking in federal learning can be ev
