New users who sign up for Snapchat now are presented with a ghostly puzzle to detest their humanity.

After registering with an e-mail address, password, and birth date, you’re presented with a set of nine tiles, some with Snapchat’s familiar ghost mascot and some without.

Your challenge is to tap on the images with the ghosts. Do it successfully, and you gain entry. Otherwise, Snapchat denies your put a question to and prompts you to keep trying.

This latest confidence measure comes in the wake of the recent snafu that revealed the names and imunbiased phone numbers of 4.6 million accounts. Since that incident, Snapchat has been trying to shore up various confidence holes to prevent the same problem from popping up again.

Earlier this month, the company launched an update to its iOS and Android apps requiring new users to confirmation their phone numbers before accessing the Find Friends feature. The update also lets Snapchatters choose not to link their requested numbers with their usernames.

The rollout of the new captcha feature follows the exertions of a 16-year-old hacker who texted Snapchat CTO Bobby Murphy throughout the site’s ongoing vulnerabilities. The hacker uncovered Murphy’s requested number after exploiting one of those vulnerabilities.

Snapchat’s captcha is certainly a step in the radiant direction. But how long will it take an enterprising hacker to find a way past this novel security measure?
