A fuel dispensing system configured to dispense fuel and further configured to authenticate content for display at the dispenser, comprising: a display (104, 304); a secure device coupled to the display (104, 304) for controlling content rendered on the display (104, 304); and a media device that obtains watermarked content for rendering on the display (104, 304), wherein the watermarked content includes embedded watermarking information, wherein the secure device comprises: a content rendering component (106, 212) for receiving the watermarking content from the media device and rendering the watermarked content on the display (104, 304); and a watermarking verifying component for determining the watermarking information embedded in the watermarked content as received from the media device by the secure device and controlling whether the watermarked content is continued to be rendered on the display (104, 304) based at least in part on the watermarking information; wherein the watermarking verifying component is configured to: determine the watermarking information embedded in the watermarked content as the watermarked content is being rendered; determine whether the watermarked content can be authenticated based on the watermarking information; terminate rendering of the watermarked content in response to a determination that the watermarked content cannot be authenticated based on the watermarking information. a display (104, 304); a secure device coupled to the display (104, 304) for controlling content rendered on the display (104, 304); and a media device that obtains watermarked content for rendering on the display (104, 304), wherein the watermarked content includes embedded watermarking information, wherein the secure device comprises: a content rendering component (106, 212) for receiving the watermarking content from the media device and rendering the watermarked content on the display (104, 304); and a watermarking verifying component for determining the watermarking information embedded in the watermarked content as received from the media device by the secure device and controlling whether the watermarked content is continued to be rendered on the display (104, 304) based at least in part on the watermarking information; wherein the watermarking verifying component is configured to: determine the watermarking information embedded in the watermarked content as the watermarked content is being rendered; determine whether the watermarked content can be authenticated based on the watermarking information; terminate rendering of the watermarked content in response to a determination that the watermarked content cannot be authenticated based on the watermarking information. a content rendering component (106, 212) for receiving the watermarking content from the media device and rendering the watermarked content on the display (104, 304); and a watermarking verifying component for determining the watermarking information embedded in the watermarked content as received from the media device by the secure device and controlling whether the watermarked content is continued to be rendered on the display (104, 304) based at least in part on the watermarking information; wherein the watermarking verifying component is configured to: determine the watermarking information embedded in the watermarked content as the watermarked content is being rendered; determine whether the watermarked content can be authenticated based on the watermarking information; terminate rendering of the watermarked content in response to a determination that the watermarked content cannot be authenticated based on the watermarking information. determine the watermarking information embedded in the watermarked content as the watermarked content is being rendered; determine whether the watermarked content can be authenticated based on the watermarking information; terminate rendering of the watermarked content in response to a determination that the watermarked content cannot be authenticated based on the watermarking information.
