Can fake reports be discriminated? [question]

Question from developer:

Can fake reports be discriminated?

Re the fake report, trigger_data will be random values of 3 bit (1 bit for view), with this latest update, where trigger_data can have up to 64 bit, we can discriminate fake reports if we avoid using 3 bit. Is this correct?

Answer:

If you use the 64-bit debug keys, you can detect which reports are noised: event-level reports associated with false trigger events will not have trigger_debug_keys. This allows you to understand how noise is applied in the API. However, it's critical to note that the 64-bit debug key is only limited to the debugging functionality. This will no longer be available after support for third-party cookies is phased out.
