Abstract: Systems and methods enforce an expiration date for an electronic document and represent the expiration visually. In various exemplary embodiments, the author specifies an expiration date for an electronic document. The expiration date is either a date stamp or is an integer representing a period of time from the creation date. In one embodiment, the access to the document is unavailable to a user after the expiration date. In various exemplary documents, the visual representation of the document ages after a milestone date is reached. In one embodiment, random pixels are added to the visual representation until the document expires. In another embodiment, an algorithm applies visual metaphor bitmaps to the document's visual representation. In one embodiment, the bitmaps are templates. In one embodiment, the document is mapped to the applied bitmaps. The document may be rendered illegible after the expiration date is reached.
