A system for serving targeted advertisements while protecting privacy receives an item of personally identifiable information (PII) from a person using a browser. The item of PII may be, for example, a telephone number or email address. The item of PII is hashed, then used to look up a node in an identity graph corresponding to the person. The node contains a link uniquely associated with the person, which is returned in an encrypted form. An envelope is created that contains the link, and is set as a first-party cookie on the person's browser. When the person uses the browser to visit another website the envelope is decrypted, and the link is separately encrypted using a different method for each of a plurality of DSPs to which the link is sent. The DSPs are used to set a display advertisement on the user's browser, the process occurring in real time.

Targeted messages are sent from a server to a client device through an app installed on the client device, but which operates without sending any personal data from the client device to any remote device. Bloom filters are created from data about the target audience and loaded in the app. User logins are resolved against the Bloom filter to targeted messages based on user identifiers. In this way, the processing to deliver a targeted message is performed on the client device, rather than on any remote device, and thus no personal information leaves the client device. Real-time view-through and click-through measurement is performed by firing conversion events to an integrated mobile network.
