The company introduced a new picture-based security layer called 'find the ghost' to prevent bots from creating several fake accounts that can potentially be used to procure phone numbers. The new layer of security shows nine images to its new users while they create their accounts.

Out of those nine images, the user will have to identify only those images which show Snapchat's ghost mascot. Snapchat created the 'ghost' security feature with the hope that bots would not be able to identify the right images.

While Snapchat implemented the image-recognition based security layer, Steven Hickson, a computer science student at Georgia Tech, came up with a '100 lines of code' that could beat the image-based security layer.

After learning of the new measure, Hickson said on his blog that he spent about half an hour writing a program that was capable of automatically detecting the company's ghost logo.
