If your face has ever appeared in a photo on anal sex videosFlickr, it could be currently training facial recognition technology without your permission.

As per a report by NBC News, IBM has been using around one million images from the image-hosting platform to train its facial recognition AI, without the permission of the people in the photos.

In January, IBM revealed its new "Diversity in Faces" dataset with the goal to make facial recognition systems fairer and better at identifying a diverse range of faces — AI algorithms have had difficulty in the past recognising women and people of colour.

Considering the potential uses of facial recognition technology, whether it be for hardcore surveillance, finding missing persons, detecting celebrity stalkers, social media image tagging, or unlocking your phone or house, many people might not want their face used for this type of AI training — particularly if it involves pinpointing people by gender or race.

IBM's dataset drew upon a huge collection of around 100 million Creative Commons-licensed images, referred to as the YFCC-100M dataset and released by Flickr's former owner, Yahoo, for research purposes — there are many CC image databases used for academic research into facial recognition, or fun comparison projects.

IBM used approximately one million of these images for their own "training dataset." According to NBC, which was able to view the collection, these have all been annotated according to various estimates like age and gender, as well as physical details — skin tone, size and shape of facial features, and pose.

But while IBM was using perfectly fine Creative Commons images, the company hadn't actually informed those whose faces appear in the almost one million images what their actual faces, not just images, were being used for.

Sure, the image subjects may have given permission for a photo of themselves to be uploaded to Flickr and listed under a CC license, but those subjects weren't given a chance to give consent for their faces to be used to train AI facial recognition systems.

NBC talked to several people whose images had appeared in IBM's dataset, including a PR executive who has hundreds of images sitting in the collection.

“None of the people I photographed had any idea their images were being used in this way,” Greg Peverill-Conti told the news outlet. "It seems a little sketchy that IBM can use these pictures without saying anything to anybody."

Flickr co-founder Caterina Fake also revealed IBM was using 14 of her photos.

"IBM says people can opt out, but is making it impossible to do so," she tweeted.

This Tweet is currently unavailable. It might be loading or has been removed.

Want to opt out? It's not that easy, although IBM confirmed to NBC that anyone who would like their image removed from the dataset is able to request it by emailing a link to the company.

The only problem? The dataset isn't publicly available, only to researchers, so Flickr users and those featured in their images have no way of really knowing if they're included.

Luckily, NBC created a handy little tool if you want to check whether you're included, you just have to drop in your username.
