All of the Android users would definitely agree with the irritating experience they suffer when someone is peeping from behind, getting their eyes glued to the mobile screens. So, in lieu of this, Google researchers are developing an ‘Electronic Screen Protector’ that will notify smartphone users when someone is looking over their shoulder.

This AI-based “Electronic Screen Protector” was developed by Google researchers Hee Jung Ryu and Florian Schroff, and demonstrated in a recent YouTube video. This tool could help professionals protect sensitive data on their smartphone screens from the staring eyes of strangers in crowded places.

How does this tool work?

This tool works by using a phone’s front-facing camera, and the system would detect whether the second set of eyes are snooping on the screen or not. If the answer is yes, it would then alert the user of their presence. Also, according to a brief description posted by the researchers, the runtime for the gaze detection is 2ms.

Utilities of the tool:

This tool would be definitely beneficial for business executives and professionals that often find themselves working in public. The feature could also serve as a useful tool to protect sensitive company data from corporate spies or potential rivals. Especially if the final functionality appears the same as the test case, automatically switching out of the app when another person’s gaze is detected.

Facial recognition and detection have emerged as major use cases for AI. It had also been found that the researchers are leaning on a Google-developed neural network called FaceNet, along with an additional neural network called GazeNet to power the Electronic Screen Protector.

In addition to this very quickly detecting gaze, the system can also perform facial recognition on the snooper in 47ms, the description noted. However, to recognize a face in each frame, it would take roughly around 115ms.

The researchers concluded in the description that, “Because of the quick, robust, and accurate gaze detection mobile model we can now easily identify the face identity and gaze simultaneously in real time. Hence, the application, an electronic screen protector, can enable its enrolled users to continue reading private and confidential contents on your mobile device, while protecting their privacy from onlookers in a crowded space such as the subway or an elevator”.
