Preventing fraud in aggregated network measurements

A computer-implemented method comprising:

• receiving reporting data comprising blindly signed impression data for a presentation of a digital component and signed conversion data for a conversion event corresponding to the presentation of the digital component, wherein the blindly signed impression data comprises blinded impression data and a first digital signature generated using the blinded impression data, and wherein the signed conversion data comprises the conversion data and a second digital signature generated using the conversion data;
• requesting verification of the first digital signature of the blindly signed impression data from a first system that generated the first digital signature using the blinded impression data;
• requesting verification of the second digital signature of the signed conversion data from a second system that generated the second signature using the conversion data;
• and
• updating impression and conversion data for the digital component in response to successfully verification of the first digital signature and the second digital signature.

A system, comprising:

• one or more processors;
• and
• one or more computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving reporting data comprising blindly signed impression data for a presentation of a digital component and signed conversion data for a conversion event corresponding to the presentation of the digital component, wherein the blindly signed impression data comprises blinded impression data and a first digital signature generated using the blinded impression data, and wherein the signed conversion data comprises the conversion data and a second digital signature generated using the conversion data;
• requesting verification of the first digital signature of the blindly signed impression data from a first system that generated the first digital signature using the blinded impression data;
• requesting verification of the second digital signature of the signed conversion data from a second system that generated the second signature using the conversion data;
• and
• updating impression and conversion data for the digital component in response to successfully verification of the first digital signature and the second digital signature.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• receiving reporting data comprising blindly signed impression data for a presentation of a digital component and signed conversion data for a conversion event corresponding to the presentation of the digital component, wherein the blindly signed impression data comprises blinded impression data and a first digital signature generated using the blinded impression data, and wherein the signed conversion data comprises the conversion data and a second digital signature generated using the conversion data;
• requesting verification of the first digital signature of the blindly signed impression data from a first system that generated the first digital signature using the blinded impression data;
• requesting verification of the second digital signature of the signed conversion data from a second system that generated the second signature using the conversion data;
• and
• updating impression and conversion data for the digital component in response to successfully verification of the first digital signature and the second digital signature.
