The #10YearChallenge was all fun and memes until last week, when a tweet moved thousands of people to worry: Are we unknowingly helping giant corporations to improve their algorithms for biometric identification and age progression?
The #10YearChallenge gained widespread traction on social media this month. It calls for posting two photos of yourself side by side — one from today and one from a decade ago — to show how you’ve changed. People are participating mostly on Facebook and Instagram, which is owned by Facebook.
Some made jokes, paid tribute to old hairstyles or drew attention to issues like global warming. Celebrities posted glamour shots that showed negligible changes from one decade to the next. (The singer Mariah Carey won this round. “I don’t get this 10 year challenge,” she wrote in a tweet, along with two identical photos side by side. “Time is not something I acknowledge.”)
But one post went viral without featuring any side-by-side photos at all. It was written by Kate O’Neill, the author of the book “Tech Humanist: How You Can Make Technology Better for Business and Better for Humans.”
“Me 10 years ago: probably would have played along with the profile picture aging meme going around on Facebook and Instagram,” she wrote in a tweet last week. “Me now: ponders how all this data could be mined to train facial recognition algorithms on age progression and age recognition.”
Her words hit a nerve.
People responded with concerns about whether they were helping the tech giant get better at identifying people. Ms. O’Neill’s post got more than 10,000 retweets and more than 20,000 likes. She expanded on her thoughts in a widely shared article in Wired.
“I wondered about why this particular thought, in this particular moment, generated so much traction,” Ms. O’Neill said on Friday, adding that she was not trying to stoke any panic.
Experts said the photos uploaded for the #10YearChallenge were drops in a very, very big bucket of data that Facebook has been collecting for years.
“We have an awful lot of data that we’re sharing all the time, and companies are collecting it and using it in various ways,” Ms. O’Neill said.
Supporters of facial recognition technologies said they can be indispensable for catching criminals or finding missing people. But critics warned that they can enable mass surveillance or have unintended effects that we can’t yet fully fathom.
Lauren A. Rhue, an assistant professor of information systems and analytics at the Wake Forest School of Business, said the #10YearChallenge could conceivably provide a relatively clean data set for a company that wanted to work on age-progression technology.
But she added that Facebook already has billions of photographs on its platform, and people should be wary of any company being in possession of such a large trove of biometric data.
“The risk in giving up any type of biometric data to a company is that there’s not enough transparency, not only about how the data is currently being used, but also the future uses for it,” she said, pointing to another form of biometric data, DNA, which is increasingly being used by law enforcement to track down suspects — something many people might not have anticipated when they volunteered saliva in exchange for help tracing their ancestral roots.
“There are things we don’t think of as being threats,” Professor Rhue said. “And then five or 10 years from now, we realize that there is a threat, but the data has already been given.”
Like the rest of us, Facebook looked different 10 years ago. In 2009, the “Like” button was introduced, and the site unveiled a new home page to make it easier for people to see their friends’ posts in real time. Facebook also reached 360 million active users in 2009; now, it has more than 2 billion.
Facebook announced that it was using facial recognition technology in 2010. When people upload photos of their friends, Facebook can use the technology to suggest the names of people in the picture. It can also alert users if they are in a photo posted by a friend.
Facebook has responded to concerns about photos and privacy in the past. The company said it does not intend to help strangers identify you, and has repeatedly pointed out that users can disable face recognition in their personal settings.
As for the 10-year challenge, Facebook said it’s just a fun trend.
“The 10-year challenge is a user-generated meme that started on its own, without our involvement,” the company said on Twitter.
Similar memes have popped up in past years, too. But this time, users are grappling with new concerns about a platform that helps people to stay in touch with grandparents but has also been used as a tool of Russian interference.
The company faced several crises in 2018. In March, it was revealed that a political consulting firm linked to President Trump had improperly obtained data on as many as 87 million Facebook users. The New York Times reported in November that company leaders had tried to play down major concerns about privacy or deflect blame, and in December that Facebook gave big technology companies more intrusive access to users’ personal data than it had previously disclosed.
“The threat to privacy has become real to people in the last year,” said Jennifer Lynch, the director of surveillance litigation for the Electronic Frontier Foundation, a digital rights group. “My hope is that people will become concerned about this vast face recognition database that Facebook has amassed and push back on Facebook, turn off face recognition in our Facebook profiles, and push for strict privacy laws at the state and federal levels.”
Ms. O’Neill said she was glad that the meme — and her tweet — started such a broad conversation about facial recognition and privacy.
“There’s a lot of opportunities for technology to do wonderful things for humanity,” she added. “But I think we need to recognize the potential downsides of it.”
