Claim 16:
17. The system of claim 11, wherein the operations comprise:
transmitting, to a first aggregation server and in response to the presentation of the digital component, a presentation report comprising encrypted presentation data for the presentation of the digital component and a first blindly signed key comprising (1) a first encrypted data element comprising an encrypted combination of at least the resource locator for the reporting system, an identifier of the client device or the user of the client device, and the phone number specified by the digital component and (ii) a first blind signature generated based on the first encrypted data element,
wherein transmitting the event report comprises transmitting, to a second aggregation server, the event report, wherein the event report comprises encrypted event data for the digital component and a second blindly signed key comprising (1) a second encrypted data element comprising an encrypted combination of at least the resource locator for the reporting system, the identifier of the client device or the user of the client device, and the given phone number of the detected phone call and (ii) a second blind signature generated based on the second encrypted data element, and
wherein the first aggregation server and the second aggregation server perform a multi-party computation process using the first and second blindly signed keys to decrypt the encrypted presentation data and the encrypted event data.
