mit's photoguard protects images from unauthorized ai edits

As AI continues to develop rapidly, chatbots are gaining the power to create and manipulate images, with Shutterstock and Adobe currently leading the way. Despite the obvious power of AI algorithms, the technology has a few pitfalls, one of which is the unauthorized manipulation of copyrighted artwork and images.

MIT CSAIL thinks it has the answer to this growing problem in the form of PhotoGuard, a new technique that alters select pixels in an image to disrupt AI’s ability to understand what the image is.

The altered pixels are known as “perturbations” and are invisible to the human eye but easily seen by AI bots as they scan the color and position of every pixel in an image. Any edits AI tries to make to a protected image will also apply to the fake pixels, resulting in an unrealistic or broken final image, thanks to PhotoGuard.

“The encoder attack makes the model think that the input image is some other image,” explained MIT student and lead author of the paper, Hadi Salman. “Whereas the diffusion attack forces the diffusion model to make edits towards some target image”. The technique sounds complex but could potentially stop malicious actors from reverse engineering protected images by adding minor edits to circumvent copyright.

“A collaborative approach involving model developers, social media platforms, and policymakers presents a robust defense against unauthorized image manipulation. Working on this pressing issue is of paramount importance today,” Salman said in a recent press release. “And while I am glad to contribute towards this solution, much work is needed to make this protection practical. Companies that develop these models need to invest in engineering robust immunizations against the possible threats posed by these AI tools”.

Cyberdrone, a leading UAV display company based in Dubai, put on a breathtaking drone light show on Monday to honor two significant football milestones: AC Milan’s 125th anniversary and the one-year anniversary of Casa Milan Dubai.

The spectacle involved 1,000 drones working in perfect harmony to project AC Milan’s iconic imagery against the city’s night sky. Highlights included the UAVs synchronizing to form the club’s iconic crest, the signature red and black jersey, and a special emblem marking its 125th year. The intricate performance demanded meticulous planning, not just in terms of choreography, but also in dealing with the necessary permits and logistics.

“Our goal was to spotlight AC Milan’s legacy through a stunning visual narrative,” explained Mohamed Munjed Abdulla, Director of Sales at Cyberdrone. “We celebrated the club’s history, its Dubai milestone, and the universal love for football. The show also enhanced AC Milan’s regional presence, growing its fanbase through a cutting-edge, memorable experience. Drone shows are unparalleled in leaving lasting impressions, making them perfect for driving partnerships and growth”.

Greta Nardeschi, AC Milan’s Regional Director for MENA, echoed the sentiment, adding: “Collaborating with Cyberdrone for this 1,000-drone performance allowed us to connect with our fans in innovative ways. It gave us a unique opportunity to surprise and inspire audiences while elevating our Club’s visibility and that of our partners. Cyberdrone truly helped us take AC Milan to new heights”.

This groundbreaking drone display sets a new benchmark for the Middle East’s sports sector, which already contributes around $2.4 billion annually to Dubai’s GDP alone. Sporting events also generate $1.76 billion in revenues across the region, while the MENA’s entertainment sector, valued at $41.13 billion, is growing at 9.41% annually, driven by rapid technological advancements.
