Abstract
A content broker can receive a request from a user's client device for access to a data stream, and determines whether the client device has a sufficient number of credits to consume the digital content. If the client device does not have a sufficient number of credits, the broker can provide the client device an opportunity to earn credits. The broker can send to the client device an advertisement stream, and a corresponding challenge query that includes a set of instructions for generating a challenge-response that proves the client device has consumed the advertisement stream. If the broker receives a valid challenge response from the client device, the broker can assign a predetermined number of credits to the user's account.
