Abstract
Systems and methods which prevent or limit access to protected content (e.g., value bearing indicia (VBI)) by a general purpose user interface application (e.g., web browser) are shown. Embodiments implement techniques to avoid displaying protected content by a general purpose user interface application, or displaying protected content during a time in which a user does not have access to particular functions of the general purpose user interface application, to protect the content from various operations, such as repeated printing, electronic copying, etc. Data presentation formatting control in the form of style sheets may be utilized to control access to content. Additionally or alternatively, executable code or an executable object may be implemented within a page or other content to control access to content. Similarly, separate areas, such as windows or pages, may be utilized to control access to content.
