Assignee: VISA INTERNATIONAL SERVICE ASSOCIATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A system, comprising:
a first user device configured to:
receive first persona data associated with a first user from at least one publisher system;
generalize the first persona data to form first generalized persona data:
generate a session key;
encrypt the first generalized persona data and the session key with a first public key of an advertisement network system to form a first ciphertext;
communicate the first ciphertext and first user identity data to a mediator system, the first user identity data associated with an identity of the first user;
receive a second ciphertext comprising an encrypted tracking token and a first encrypted targeted advertisement based on the first generalized persona data from the advertisement network system via the mediator system; and
decrypt the second ciphertext with the session key to form a first targeted advertisement and a tracking token,

wherein the mediator system is configured to:
generate first pseudo-identity data associated with the first user identity data; and
communicate the first ciphertext and the first pseudo-identity data to the advertisement network system,

wherein the advertisement network system is configured to:
decrypt the first ciphertext with a first private key of the advertisement network to form the first generalized persona data and the session key;
determine the first targeted advertisement based on the first generalized persona data;
generate a tracking token based on the first targeted advertisement;
encrypt the first targeted advertisement and the tracking token with the session key to form the second ciphertext, the second ciphertext comprising the first encrypted targeted advertisement and the encrypted tracking token; and
communicate the second ciphertext and the first pseudo-identity data to the mediator system,

wherein the at least one publisher system comprises a first publisher system, wherein:
the first user device is configured to communicate the first targeted advertisement and the tracking token to the first publisher system;
the first publisher system is configured to present the first targeted advertisement to the first user;
the first publisher system is configured to communicate the tracking token to the mediator system; and
the mediator system is configured to communicate the tracking token to the advertisement network system.
