Abstract: Systems and methods are disclosed for managing online advertising data secure sharing. One method includes receiving, at a server, a request for proprietary data from a data consumer, the request including a data consumer identifier; retrieving, from a database of proprietary data, proprietary data based on the request; determining, by the server, whether the retrieved proprietary data is at least one of: designated to be processed and designated to have privileges set; processing, by the server, the proprietary data when the server determines the proprietary data is designated to be processed; setting one or more privileges to the proprietary data using the certificate associated with the data consumer identifier when the server determines the proprietary data is designated to have privileges set; encrypting the proprietary data using the certificate associated with the data consumer identifier; and transmitting the encrypted proprietary data to the data consumer.

Abstract: An advertiser participating in a method of targeting based on first party cookies may update its DNS record to include a subdomain that redirects to a server associated with an ad network. The ad network may incorporate that advertiser's subdomain in an ad pixel tag published on one or more of the advertiser's web pages, to set a cookie on the advertiser's domain. Specifically, when a user visits one of the advertiser's web pages, the ad pixel tag may be redirected by the advertiser's DNS update to an ad network server for receipt of a cookie that matches the subdomain. The ad network may distribute to its publishers an ad call that checks for the presence of any first party domain cookies set via the second stage, and then pass any such cookie data to the network's ad servers to decide which ad to serve.
