Secured management of data distribution restrictions

A system, comprising:

• a memory device;
• and
• one or more processors configured to access the memory device and execute instructions that, upon execution, cause the one or more processors to perform operations comprising:
• generating, by an application and for a digital component presented in the application, a universal identifier that is an encrypted version of a combination of (i) a campaign identifier for a content source that provides the digital component and (ii) a domain of the content source;
• updating, by the application, a set of universal identifiers that have been created for digital components presented by the application over a specified time period based on the generated universal identifier;
• identifying, by the application, a set of blocked universal identifiers corresponding to universal identifiers that have been (i) generated by the application, and (ii) blocked from being used to present future digital components in the application;
• generating, by the application, a probabilistic data structure representing the set of blocked universal identifiers;
• creating, by the application, multiple shares of the probabilistic data structure;
• transmitting, by the application, different ones of the multiple shares to different servers;
• receiving, by the application, a separate response generated by each of the different servers based on the different ones of the multiple shares transmitted to the different servers;
• and
• identifying, by the application and based on a combination of the separate responses, a digital component to present in the application.

A non-transitory computer readable medium storing instructions that, when executed by one or more data processing apparatus, cause the one or more data processing apparatus to perform operations comprising:

• generating, by an application and for a digital component presented in the application, a universal identifier that is an encrypted version of a combination of (i) a campaign identifier for a content source that provides the digital component and (ii) a domain of the content source;
• updating, by the application, a set of universal identifiers that have been created for digital components presented by the application over a specified time period based on the generated universal identifier;
• identifying, by the application, a set of blocked universal identifiers corresponding to universal identifiers that have been (i) generated by the application, and (ii) blocked from being used to present future digital components in the application;
• generating, by the application, a probabilistic data structure representing the set of blocked universal identifiers;
• creating, by the application, multiple shares of the probabilistic data structure;
• transmitting, by the application, different ones of the multiple shares to different servers;
• receiving, by the application, a separate response generated by each of the different servers based on the different ones of the multiple shares transmitted to the different servers;
• and
• identifying, by the application and based on a combination of the separate responses, a digital component to present in the application.
