Abstract
The systems and methods described herein can enable the indirect transmission of session data between different domains. The system can pass the session data through a hashing function so that the data from a given domain remains private and secure to the specific domain. The system can generate clusters of associated domains for a given client device that the system can use to maintain a session between the client device and the domain.
Claims20
A method, comprising:
- receiving, by a data processing system and from a first node that hosts a web page, a request that includes an identifier corresponding to a client device that is requesting the web page;
- generating, by the data processing system, a hash of the identifier;
- identifying, in a data storage device, a set of candidate nodes that has an unexpired connection to the hash of the identifier;
- transmitting, by the data processing system and to the first node, an indication of the set of candidate nodes that has an unexpired connection to the hash of the identifier;
- receiving, by the data processing system and from at least one of the candidate nodes in the set of candidate nodes, a notification that the at least one of the candidate nodes received, from the client device, a pixel request generated by the first node based on the indication of the set of candidate nodes that were transmitted to the first node;
- and
- transmitting, by the data processing system and to the client device, a cluster identifier of a cluster that includes the first node and the at least one of the candidate nodes that received the pixel request;
- receiving, by the data processing system and from the client device, a content request including the cluster identifier;
- and
- transmitting, by the data processing system and to the client device, content selected using the cluster identifier.

A system, comprising:
- a memory device;
- and
- one or more processors configured to interact with the memory device and execute instructions that cause the one or more processors to perform operations comprising:
- receiving, from a first node that hosts a web page, a request that includes an identifier corresponding to a client device that is requesting the web page;
- generating a hash of the identifier;
- identifying, in a data storage device, a set of candidate nodes that has an unexpired connection to the hash of the identifier;
- transmitting, to the first node, an indication of the set of candidate nodes that has an unexpired connection to the hash of the identifier;
- receiving, from at least one of the candidate nodes in the set of candidate nodes, a notification that the at least one of the candidate nodes received, from the client device, a pixel request generated by the first node based on the indication of the set of candidate nodes that were transmitted to the first node;
- and
- transmitting, to the client device, a cluster identifier of a cluster that includes the first node and the at least one of the candidate nodes that received the pixel request;
- receiving, from the client device, a content request including the cluster identifier;
- and
- transmitting, to the client device, content selected using the cluster identifier.

A non-transitory computer readable medium storing instructions that, upon execution by one or more data processing apparatus, cause the one or more data processing apparatus to perform operations comprising:
- receiving, from a first node that hosts a web page, a request that includes an identifier corresponding to a client device that is requesting the web page;
- generating a hash of the identifier;
- identifying, in a data storage device, a set of candidate nodes that has an unexpired connection to the hash of the identifier;
- transmitting, to the first node, an indication of the set of candidate nodes that has an unexpired connection to the hash of the identifier;
- receiving, from at least one of the candidate nodes in the set of candidate nodes, a notification that the at least one of the candidate nodes received, from the client device, a pixel request generated by the first node based on the indication of the set of candidate nodes that were transmitted to the first node;
- and
- transmitting, to the client device, a cluster identifier of a cluster that includes the first node and the at least one of the candidate nodes that received the pixel request;
- receiving, from the client device, a content request including the cluster identifier;
- and
- transmitting, to the client device, content selected using the cluster identifier.
