Abstract
A method for maintaining user privacy in advertisement networks may include receiving first persona data associated with a first user from at least one publisher system. The first persona data may be generalized to form first generalized persona data. A session key may be generated. The first generalized persona data and the session key may be encrypted with a first public key of an advertisement network system to form a first ciphertext. The first ciphertext and first user identity data may be communicated to a mediator system. The first user identity data may be associated with first user's identity. A first encrypted targeted advertisement may be received based on the first generalized persona data from the advertisement network system via the mediator system. The first encrypted targeted advertisement may be decrypted with the session key to form a first targeted advertisement. A system and computer program product are also disclosed.
