Google has the definitive solution to protect your private conversations from the furtive looks of the most gossips. According to The Verge, two researchers from Google have developed an application that detects when someone is looking at the screen of your mobile.

The application, which is called E-screen protector, uses technology with artificial intelligence to detect faces and looks in the images taken by the front camera of the mobile. If the application is activated, the mobile detects these looks while you use other applications, such as WhatsApp or Messenger.

As you can see in the demo video posted by the same creators of the application, “E-screen protector” is not visible until it detects a suspicious look. At that moment, the message application is automatically closed and the image captured by the front camera appears.

The suspect’s face is inside a box and a filter with the effect of ‘rainbow vomit’ is applied. According to its creators, the screen protector system works with all kinds of lighting and the reaction time of the application is only two milliseconds.

The first criticisms focus on the lack of privacy of having the camera permanently on

Although the application is still under development and is not found in the app stores, the E-screen protector has already begun to receive criticism. The most repeated is the lack of privacy since the electronic protector requires to have the camera in operation all the time. Although the image does not appear on the screen, the camera is activated and constantly analyzes the environment.

In addition to being a risk if someone manages to access the mobile remotely, the taking of images could also be a legal problem if they were recording in private spaces or to people who have not given their authorization.

The filter that appears on the face of the culprit has also been criticized. The rainbow with stars that comes out of the mouth in the form of vomit is one of Snapchat’s most iconic filters since its launch in 2015.

Google has not confirmed whether it will add this feature to their Pixel phones or the Android system. At the moment, the creators of the application, Hee Jung Ryu, and Florian Schroff will present the software at the conference on systems of information processing neuronal (NIPS) held this week in California.
