Abstract
A method for sending a message from a first device to a second device includes transmitting the message by the first device, receiving the message by the second device, displaying the message on the second device, activating a camera on the second device to capture image data regarding a field of view of the camera, activating one or more light sensors located close to the camera to capture data regarding an amount of ambient light detected by the light sensors, and monitoring the image data to detect a possible presence of one or more suspected camera lenses within the field of view of the camera. Upon the detection of a possible presence of one or more suspected camera lenses within the field of view of the camera or upon detection of a sudden decrease of the amount of ambient light, displaying of the message on the second device is ceased.
