摘要： A method, apparatus, and system are provided to facilitate protecting media such as images, documents, video streams, and the like, from unauthorized copying or distribution. The method is based on requiring certain conditions to be filled prior to, and during, display of the media on a user display. The conditions for display may require pointing device cursor placement, operating certain keys, and the like. Permissions are granted to users by the media owners and the permissions are checked prior to display. Thus the user is prevented from copying the media and using it illicitly, and the media owner may share media while at the same time maintaining control over the use thereof. The system may also be utilized to provide time-limited access to certain materials.
