Beauty is in the eye of the beholder, they say. And in a futuristic beauty contest (though some might argue judging people based on their looks isn't all that forward-thinking), the beholders are a bunch of robots. The Beauty.AI 2.0 contest is an international beauty contest judged by artificial intelligence. The robot jury is comprised of five algorithms -- RYNKL (judging your wrinkles), PIMPL (complexion), MADIS (how you compare to models within your age and racial group), Symmetry Master (symmetry of your face) and AntiAgeist (how old do you really look?). The objective of this beauty contest wasn't simply to show people what robots think are beautiful -- it was to test biogerontologists and data scientists' theory "that in the near future machines will be able to get a lot of vital medical information about people's health just by processing their photos," the Beauty.AI website says.

It's a site that only lets in the genetically blessed based on some mysterious beauty metric – and today the personal data of 1.1 million BeautifulPeople.com It's only a slice of data from 2015, and the company says the leak's been patched up, but data once stolen can never be controlled: and so 1.1 million names of self-declared Beautiful People will now begin circulating. Like the Ashley Madison hack – which left 39 million people on a dating site for married people exposed and their names suddenly searchable – there's a joy in shaming people who would sign up for such a thing. "Online dating for beautiful people only," the website announces. "BeautifulPeople.com is the largest internet dating community exclusively for the beautiful," it reads.

BeautifulPeople.com, you may remember, is a dating site that allows members to vote on hopeful enlistees based on their looks, ensuring that people who belong meet certain standards of both attractiveness and shallowness. It bills itself as "a dating site where existing members hold the key to the door." Turns out, the site maybe should have put them in charge of server security, as well. The personal data of 1.1 million members is currently for sale on the black market, after hackers took it from an insecure database. Last December, security researcher Chris Vickery made a curious discovery while browsing through Shodan, a search engine that lets people look for internet-connected devices.
