Abstract

System and method for associating general data with an end-user based on the domain name system (DNS) resolver that the end-user uses to map the canonical domain names of internet services to their associated network addresses. The present invention elegantly addresses concerns of scale regarding the key-space, for example the global number of distinct DNS resolvers, and the data-space, for example the number of distinct geographical areas to associate.

Claims

1. A method of associating general data with end users comprising:

receiving, from an end user to a DNS resolver system, a request for an IP address associated with a stage of a key association process domain name;

providing an association key system comprising a plurality of association key servers,

determining, on the DNS resolver system, an appropriate association key system based on the requested domain name and on information about the end user device derived from the request;

transmitting, from the DNS resolver system to the end user device, the IP address of an appropriate association key server within the association key system;

receiving from the end user to the association key system, a request comprising the domain name of the current stage of the key association process and metadata derived in previous stages regarding the key association process in progress;

determining on the association key system, if the key association process is not complete, the domain name associated with the next stage in the key association;

concatenating, on the association key system, previously received metadata to include a key fragment of the association key system'"'"'s presence at the current stage of the key association process;

determining, on the association key system when the key association process is complete, a complete association key associated with the end user using the concatenated metadata from prior stages;

wherein potential keys are encoded as an M digit number of base N, where M is the number of key association process stages and N is the number of association key servers; and

transmitting from the association key system to the end user device a protocol specific redirection to the domain name of the next stage in the key association process information comprising the concatenated metadata or the domain name of the service endpoint including the complete association key associated with the end user device.
