Re: [private-measurement] Interoperable Private Attribution (IPA) (#9)

Having read the IPA proposal, I have the following question concerning the addition of differential private noise on aggregated trigger values. How does one compute (estimate) the sensitivity of the trigger value in a setting like IPA, where the range of the trigger values are never revealed to the aggregators.

Do you in this case apply local differential privacy, meaning the trigger sites that generates these trigger events, add already properly sampled local differential private noise to each trigger value before encrypting it and submit it to the MPC network?
