The average Londoner is caught on camera more than 300 times a day – that’s one CCTV camera for every 14 people, and that number’s predicted to rise to one in 11 in the next five years. Thankfully, researchers at Northeastern University, MIT, and IBM have designed a top that makes you invisible to facial recognition technology.

Normally, surveillance algorithms work by recognising a characteristic in an image, drawing a ‘bounding box’ around it, and assigning a label to that object. To interrupt this, the t-shirt uses colourful, pixelated patterns to confuse the technology into thinking you don’t exist. In other words, the clusters of pixels are placed to confuse the AI’s classification and labelling system, making it harder for it to map out your facial features.

“The adversarial t-shirt works on the neural networks used for object detection,” Xue Lin, an assistant professor of electrical and computer engineering at Northeastern, told Wired.

According to Lin, wearing the t-shirt makes you 63 per cent less likely to be detected by digital surveillance technology, but it’s not failsafe. “We still have difficulties in making it work in the real world because there’s that strong assumption that we know everything about the detection algorithm,” she said. “It’s not perfect, so there may be problems here or there.”

In the meantime, people are turning to make-up to throw off facial recognition algorithms.  This includes blocking out shapes in geometric patterns, applying flowers to your face to obscure key features such as the eyes or nose-bridge, or applying Juggalo clown face, because fuck the system, I guess?
