The present invention provides a method, system, and program product for preventing unauthorized changes to an electronic document (or a portion thereof). Specifically, under the present invention, an electronic document having a user interface control (UIC) is obtained. It is then determined whether a portion of the electronic document for which the user interaction is being attempted is protected by examining at least one of: a signature status of data associated with the UIC, or an archival status of the UIC. Based on this determination, the user interaction will be denied if it affects at least one of: the data, or a presentation property that affects an interpretation of the data is prevented. A notice indicating the denial of the user interaction can then be communicated to a user/party attempting the user interaction.
