FOX NEWS - By now, all of your social media feeds are probably brimming with then-and-now pictures showing the "glow-up" or positive transformations of people — including celebrities, friends, family or random folks — sharing decade-old images of themselves, alongside current photographs.
Although the meme that's proliferated on Facebook, Instagram and Twitter is a great way to show much you've changed over the years, and users are freely sharing the images, one technologist and follower of the meme pondered whether the entire challenge was actually something more sinister and sparked a discussion about the technology in the process.
Kate O'Neill, who authored a book called "Tech Humanist," went on to theorize that, if you were training a facial recognition program on age-related traits, it would be useful to have a large data set taken at a fixed number of years apart.
"Thanks to this meme, there's now a very large data set of carefully curated photos of people from 10 years ago and now. Is it bad that someone could use it to train a facial recognition algorithm? Not necessarily," O'Neill said on Twitter, noting that such technology could be used to find missing children.
A number of technology companies, including Facebook and Amazon, have been criticized over the privacy implications of facial recognition technology.
A Facebook spokesperson provided the following statement to Fox News:
“This is a user-generated meme that went viral on its own. Facebook did not start this trend, and the meme uses photos that already exist on Facebook. Facebook gains nothing from this meme (besides reminding us of the questionable fashion trends of 2009). As a reminder, Facebook users can choose to turn facial recognition on or off at any time.”
