Google researchers reveal 'stranger danger' app that can warn you when someone is reading your phone screen over your shoulder
- App uses a front facing camera and AI to detect faces
- Can sound alert when more than one person is looking at the screen?
- ?Shows a picture of the peeking perpetrator with a vomit rainbow
We've all snuck a glance at a stranger's phone on the subway - but a new app could out you as a 'shoulder surfer'.
Google researchers have revealed a new app for the Pixel that uses its front facing camera along with AI to scan for faces.
When it spots a second person looking at the screen, it alerts the user - by sending a picture of the offender with rainbow vomit streaming from their mouth.

The app, dubbed an 'electronic screen protector', can recognize a person’s gaze in 2 milliseconds, the researchers say.?When it spots a second person looking at the screen, it alerts the user - by sending a picture (seen above) of the offender with rainbow vomit streaming from their mouth.
Google researchers Hee Jung Ryu and Florian Schroff will reveal their app next week at the?the Neural Information Processing Systems conference in Long Beach, California, according to Quartz.
The researchers say that it could be turned on when reading sensitive information or watching video in a public place.?

The pair uploaded their video for the presentation to YouTube.
It shows ?the app in action, and recognising users sneaking a peek instantly.
In the video, when a stranger's gaze is detected as the phone's owner types a text message, the screen automatically switches to the front camera and uses a giant rainbow to point to the stranger's face.?
When the stranger looks away, the screen turns back to the text messaging app.
It is believed the app is programmed using TensorFlowLite, Google’s latest venture into AI and machine learning.

It uses the processor in your phone to perform complex visual analysis, rather than relying on servers.?
The video suggests the researchers are using FaceNet, a facial-recognition neural network developed by Schroff and other Google researchers in 2015, as well as GazeNet, a gaze-estimation neural network recently described by researchers in Japan and Germany.?
The company also holds a 2003 patent for tracking a computer mouse pointer with a person’s vision, as well as Pay-Per-Gaze ad tracking, according to Quartz.??
