An electronic device may include a processor and a blacklist database listing objects not to be displayed. The processor is to remove an object from a frame before the frame is sent to or received from an electronic device when the object is listed in the blacklist database. In an example, an electronic device can include logic to receive, in a processor, a frame to be sent to or received from an electronic device and logic to scan the frame to identify an object. The electronic device can also include logic to determine if the object is listed in a blacklist database. The electronic device further includes logic to modify the frame to remove the object when the object is listed in the blacklist database and logic to transfer the frame for processing.
