Can there be signature rule documents and related documents in the screenshot

**Additional context**  
Whether there is the function of callback with signed parameters. When receiving callback data, perform signature verification and data processing only after passing  
We are worried that the data will be unsafe after being transferred through the network. We can’t let the data in without verification
