A server computer coupled to a distributed advertising system network has a web server adapted for running a web application having access to advertiser metadata and other advertiser data. A client computer coupled to the network includes first software configured to collect and save in first memory user data locally in a user device, but not send that data to the server computer, second software configured to download via the network from the web server and save in a first memory advertiser metadata in a manner where the entire advertiser metadata file needs to be downloaded every time, and third software configured, when accessing a website or social network, to match local data against the local copy of advertiser metadata residing at the user's device, and if there are desirable advertisers to display, to download parts of the other advertiser data related to those advertisers and display targeted ads. |
