Service processing method and apparatus, network device, and storage medium

A network device, comprising a processor and a memory, wherein the memory stores a program or instructions capable of running on the processor, wherein the program or instructions, when executed by the processor, implements the steps of:

• receiving a service processing request of a second network device for a target privacy protection service;
• obtaining, based on the service processing request, a target privacy processing model obtained through joint training with the second network device;
• and
• performing, by using the target privacy processing model, privacy processing on network data related to the target privacy protection service, and then transmitting the network data to the second network device, or
• wherein the program or instructions, when executed by the processor, implements the steps of:
• transmitting a service processing request for a target privacy protection service to a first network device;
• and
• receiving a service processing result returned by the first network device, wherein the service processing result is a result obtained after privacy processing is performed, by using a target privacy processing model, on network data related to the target privacy protection service after the first network device obtains, based on the service processing request, the target privacy processing model obtained through joint training with the network device.
