Analyzing individual information from multi-database system

A system comprising:

• a request server for receiving data representing user credentials from an application server and assigning a transient token to the received user credentials and initiating transmission of the user credentials and the assigned transient token, wherein the transient token assigned to the received user credentials is generated independent of the user credentials;
• a de-identification server for receiving the user credentials and the assigned transient token from the request server and generating a unique token from the user credentials received from the request server, and initiating transmission of the generated unique token and the assigned transient token;
• a de-identified data server for receiving the generated unique token and the assigned transient token from the de-identification server and receiving data representing personal information corresponding to the user credentials based on matching the generated unique token and a token corresponding to the user credentials of the personal information stored at the de-identified data server, and initiating transmission of the received personal information and the assigned transient token;
• an analytic server for receiving the personal information and the assigned transient token from the de-identified data server and initiating transmission to the request server, personalized content attained from the received personal information and the transient token, the request server initiating transmission to the application server the attained personalized content based on the transient token being received at the request server, wherein transmission of the attained personalized content to the application server is initiated upon matching the transient token received from the analytic server to the transient token transmitted to the de-identification server.

One or more computer readable storage devices storing instructions that are executable by a processing device, and upon such execution cause the processing device to perform operations comprising:

• receiving, at a request server, data representing user credentials from an application server;
• assigning a transient token to the received user credentials and initiating transmission of the user credentials and the assigned transient token to a de-identification server, wherein the transient token assigned to the received user credentials is generated independent of the user credentials;
• generating, at the de-identification server, a unique token from the user credentials received from the request server, and initiating transmission of the generated unique token and the assigned transient token to a de-identified data server;
• receiving, at the de-identified data server, data representing personal information corresponding to the user credentials based on matching the generated unique token and a token corresponding to the user credentials of the personal information stored at the de-identified data server, and initiating transmission of the received personal information and the assigned transient token to an analytic server;
• initiating transmission, at the analytic server, to the request server personalized content attained from the received personal information and the transient token;
• and
• initiating transmission, at the request server, to the application server the attained personalized content based on the transient token being received at the request server, wherein transmission of the attained personalized content to the application server is initiated upon matching the transient token received from the analytic server to the transient token transmitted to the de-identification server.
