DIGITAL SIGNATURES FOR ONLINE ADVERTISEMENT SECURITY

摘要

Online advertisements may be verified before being rendered. In one example, an ad control is incorporated into an application or web page. When the ad control is to present an ad, the ad control requests an ad from an ad provider. Ads that are provided to the ad control have previously been submitted for certification, and have received a certificate. When the ad control receives the ad, it verifies the certificate using a digital signature. If the certificate verifies, then the ad is deemed acceptable to render, and the ad control renders the ad. Otherwise, the ad is not deemed acceptable to render, and the ad control requests another ad from the ad provider.
