Developed by a privacy software company called ContentGuard, the iOS-enabled app uses a common optical illusion to make your sent photos a lot harder for the receiver to screenshot.
"Everyone is becoming more conscious of the digital trail they leave. It seems as though there isn't a day that goes by where we do not see a headline about the consequences of inadvertent or malicious digital publication of our private lives," its developer Scott Richardson was quoted as saying in media reports.
Yovo uses the Barrier Grid illusion, which is similar to what we might experience driving past a picket fence.
As we move fast, our eyes tend to see the stationary scene behind the palings rather than the palings themselves, CNET reported.
When we take a picture, the app overlays a blurred grille over the image. When the receiver opens the image, the grille moves, allowing them to see the picture. But if they try to take a screenshot, it will always result in an image with blurred sections.
The app can be downloaded free from the iTunes app store.
