Abstract: A method includes, in a server residing in a network of interconnected computers, receiving user data, dissecting the received user data into a plurality of key/value pairs, iterating through the plurality of key/value pairs, generating a new data structure in the memory of the server for each key/value pair that do not exist, inserting a UserID into a set associated for a specific key/value pair, storing the key/value sets, and destroying the received user data.

Abstract: A method and system for attributing activity to a user includes sharing information with an analytics server while attributes and a user profile cannot be tracked back to the original user from the analytics server. A temporary ID included in the shared information is destroyed, thus eliminating any trace back.

Abstract: A method and system for attributing activity to a user includes sending a first request for content from a browser executing on a consumer device to a first content provider. The first content provider responds to the request by generating a browser identifier and sending the browser identifier along with the requested content to the browser. Next, the user browser sends a second request for content to a second content provider. The user shares personal identification information with the second content provider. The second content provider contacts an attribute server to retrieve attributes associated with the user and generates a temporary ID. The second content provider shares the attributes and the temporary ID with an analytics server. The second content provider also instructs the browser to share the browser ID and the temporary ID with a user profile server.
