Using secure multi-party computation to improve content selection process integrity

A system comprising:

• one or more processors;
• and
• one or more memory elements including instructions that, when executed, cause the one or more processors to perform operations including:
• receiving, by a first server of a secure multi-party computation (MPC) system and from an application on a user device, a request for a digital component;
• parsing, by the first server, the request into two or more distinct sub-requests;
• transmitting, by the first server of the secure MPC system, each of the two or more distinct sub-requests to a different server;
• receiving, by the first server and from a separate server in response to transmitting the two or more distinct sub-requests, a first set of candidate selection values;
• performing, by the first server in collaboration with one or more second servers of the MPC system, a selection process to generate a selection result for a winning digital component comprising:
• merging, by the first server, the first set of candidate selection values and a set of cached selection values to create a final set of candidate selection values;
• sorting, by the first server, the final set of candidate selection values according to the values of the candidate selection values;
• and
• applying, by the first server, each rule of a set of two or more selection rules;
• and
• transmitting, by the first server in collaboration with the one or more second servers and to the user device, the selection result for the winning digital component.

A computer storage medium encoded with instructions that when executed by a distributed computing system cause the distributed computing system to perform operations comprising:

• receiving, by a first server of a secure multi-party computation (MPC) system and from an application on a user device, a request for a digital component;
• parsing, by the first server, the request into two or more distinct sub-requests;
• transmitting, by the first server of the secure MPC system, each of the two or more distinct sub-requests to a different server;
• receiving, by the first server and from a separate server in response to transmitting the two or more distinct sub-requests, a first set of candidate selection values;
• performing, by the first server in collaboration with one or more second servers of the MPC system, a selection process to generate a selection result for a winning digital component comprising:
• merging, by the first server, the first set of candidate selection values and a set of cached selection values to create a final set of candidate selection values;
• sorting, by the first server, the final set of candidate selection values according to the values of the candidate selection values;
• and
• applying, by the first server, each rule of a set of two or more selection rules;
• and
• transmitting, by the first server in collaboration with the one or more second servers and to the user device, the selection result for the winning digital component.
