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”.

samsung smart glasses teased for january software reveal imminent

Samsung appears poised to introduce its highly anticipated smart glasses in January 2025, alongside the launch of the Galaxy S25. According to sources in Korea, the company will first reveal the accompanying software platform later this month.

As per a report from Yonhap News, Samsung’s unveiling strategy for the smart glasses echoes its approach with the Galaxy Ring earlier this year. The January showcase won’t constitute a full product launch but will likely feature teaser visuals at the Galaxy S25 event. A more detailed rollout could follow in subsequent months.

Just in: Samsung is set to unveil a prototype of its augmented reality (AR) glasses, currently in development, during the Galaxy S25 Unpacked event early next year, likely in the form of videos or images.

Additionally, prior to revealing the prototype, Samsung plans to introduce…

The Galaxy Ring, for example, debuted in January via a short presentation during Samsung’s Unpacked event. The full product unveiling came later at MWC in February, and the final release followed in July. Samsung seems to be adopting a similar phased approach with its smart glasses, which are expected to hit the market in the third quarter of 2025.

A Collaborative Software Effort

Samsung’s partnership with Google has played a key role in developing the smart glasses’ software. This collaboration was first announced in February 2023, with the device set to run on an Android-based platform. In July, the companies reiterated their plans to deliver an extended reality (XR) platform by the end of the year. The software specifics for the XR device are expected to be unveiled before the end of December.

Reports suggest that the smart glasses will resemble Ray-Ban Meta smart glasses in functionality. They won’t include a display but will weigh approximately 50 grams, emphasizing a lightweight, user-friendly design.

Feature Set And Compatibility

The glasses are rumored to integrate Google’s Gemini technology, alongside features like gesture recognition and potential payment capabilities. Samsung aims to create a seamless user experience by integrating the glasses with its broader Galaxy ecosystem, starting with the Galaxy S25, slated for release on January 22.
