The app is looked upon as a tool to fight back the new-age phenomenon called sexting that often includes teens sending sexually explicit messages/nude photos to each other. The app comes with an image-recognition algorithm that can identify such sexually implicit images and immediately send out alerts to parents.

 

The aptly named Gallery Guardian app will make its debut later this month, but BBC managed to get a sneak peek into the app. The app has been trained to detect humans, and more the skin in the image, means more the chances of it being a 'suspicious image detected.'

 

So as soon as a child downloads a nude image, the parent will be sent an alert that reads 'Suspicious Image detected.' According to DailyMail, Android users won’t just be informed about the nude image, but also the source via which it was sent. For instance, WhatsApp or downloaded from the Internet. Gallery Guardian will sync with up to six devices. 

 

However, the report adds that the app couldn't detect a photo that was clothed, but exposing private body parts. The app is still learning and the developer is trying to train it to recognise genetalia, and the hindrance is the different shape and sizes.
