Audience targeting with universal profile synchronization

A computer-implemented method for universal synchronization of profiles of client computers targeted for the delivery of content over a computer network, the method comprising:

• receiving, over a network, profile data for a plurality of client computers from a collection domain;
• associating, by at least one processor in a database, profile data of a client computer of the plurality of client computers with a global profile identifier;
• associating, by the at least one processor in the database, the associated global profile identifier with a first set of cookie related information;
• receiving, over the network, new profile data for the client computer of the plurality of client computers using the first set of cookie related information;
• receiving, over the network, an authoritative identification of the client computer from a collection domain;
• correlating the client computer with the global profile identifier based on the received authoritative identification;
• receiving, over the network, a second set of cookie related information from the client computer;
• determining that the second set of cookie related information received from the client computer does not include at least part of the first set of cookie related information;
• and
• transmitting, over the network, to the client computer, cookie related information which was determined not to be included in the second set of cookie related information received from the client computer.

A system for universal synchronization of profiles of client computers targeted for the delivery of content over a computer network, the system including:

• a data storage device that stores instructions for universal synchronization of profiles of client computers targeted for the delivery of content over a computer network;
• and
• a processor configured to execute the instructions to perform a method including:
• receiving profile data for a plurality of client computers from a collection domain;
• associating profile data of a client computer of the plurality of client computers with a global profile identifier;
• associating the associated global profile identifier with a first set of cookie related information;
• receiving new profile data for the client computer of the plurality of client computers using the first set of cookie related information;
• receiving an authoritative identification of the client computer from a collection domain;
• correlating the client computer with the global profile identifier based on the received authoritative identification;
• receiving a second set of cookie related information from the client computer;
• determining that the second set of cookie related information received from the client computer does not include at least part of the first set of cookie related information;
• and
• transmitting to the client computer, cookie related information which was determined not to be included in the second set of cookie related information received from the client computer.

A non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to perform a method for universal synchronization of profiles of client computers targeted for the delivery of content over a computer network, the method comprising:

• receiving, over a network, profile data for a plurality of client computers from a collection domain;
• associating, by at least one processor in a database, profile data of a client computer of the plurality of client computers with a global profile identifier;
• associating, by the at least one processor in the database, the associated global profile identifier with a first set of cookie related information;
• receiving, over the network, new profile data for the client computer of the plurality of client computers using the first set of cookie related information;
• receiving, over the network, an authoritative identification of the client computer from a collection domain;
• correlating the client computer with the global profile identifier based on the received authoritative identification;
• receiving, over the network, a second set of cookie related information from the client computer;
• determining that the second set of cookie related information received from the client computer does not include at least part of the first set of cookie related information;
• and
• transmitting, over the network, to the client computer, cookie related information which was determined not to be included in the second set of cookie related information received from the client computer.
