A method, device and computer readable medium for controlling the presentation of primary content (such as an e-mail message, web page, computer game or other executable program) is described such that secondary content, including advertising, is always presented to a user in the manner that is intended. An audience management system, through the use of audience management software and audience management metadata, ensures that it is not possible for a user to be presented with primary content without also being presented with secondary content as it was intended to be presented. The primary content is delivered to a user in encrypted form to prevent unauthorized access. The user is also provided with the secondary content, audience management metadata specifying rules for the presentation of the primary content and the secondary content at the user's computer, and audience management software that authenticates all the aforesaid components. Digital rights management may also form part of the feature set of the audience management software. Targeting of secondary content is also possible. Countermeasures against attack by hackers to corrupt the primary content, secondary content and/or the audience management metadata are also described. |
