Abstract
A method for authenticating direct mirroring connection between a target screen device currently presenting images or video and a mobile device is provided. The method includes capturing currently displayed image by the mobile device, detecting image feature detection by image processing of the captured image, sending capture image features to a dongle device connected to the target screen device, identifying similar features by comparing the captured image features to the features of currently displayed image of the representation or the video frame, analyzing geometrical transformation between similar image features for verifying the correspondences between the set of putative points of the captured image and the real copy of the presented image and computing the homography between the images by the verified putative point correspondences and incase the computed homography is above a predefined threshold authenticate the user as currently located in the vicinity of the target screen.
