Summary:The invention discloses a data processing method and device, equipment and a storage medium. The method comprises the following steps: updating a first global data model of a data application party according to a local data model provided by a data provider to obtain a second global data model; calculating a first anchor sample loss value, corresponding to the first global data model, of the anchor sample and a second anchor sample loss value, corresponding to the second global data model, of the anchor sample based on the anchor sample of the data feature of the ith data category in the N data categories of the data application party; and according to the first anchor sample loss value and the second anchor sample loss value, generating evaluation data used for determining whether the data provider is a malicious data provider or not. Therefore, the data application party combines the local first global data model and the local data model provided by the data provider and used for joint modeling, and indepen
