Abstract
A computer system includes a content delivery system that delivers digital content from a source to a mobile device, which in turn presents the digital content to a recipient computer system. The recipient computer system can validate that the digital content presented by the mobile device is authorized by the source of that digital content without the recipient computer system communicating with the content delivery system for such validation. Digital content presented on a mobile phone can be validated by a recipient as being authorized by a source, without a connection to a centralized database. To perform such validation, the computer system uses i) a transaction location determined at the time of a transaction based on information received from the mobile device, and ii) a time-varying, non-predictable code associated with the transaction location.
