Latest Technology News: MIT’s new tool ‘PhotoGuard’ to help against A

PhotoGuard prevents misuse of your photos by altering an image’s pixels in a way that makes it difficult for AI to understand.

The Computer Science and Artificial Intelligence Laboratory (CSAIL), part of the Massachusetts Institute of Technology (MIT) in the United States, has come up with a way to protect your photos from AI tampering.

Called PhotoGuard, the tool prevents the misuse of your photos by altering an image’s pixels in a way that makes it difficult for AI to understand. Called “disturbances”, they are invisible to the human eye but can still be read by AI, reported Engage.

This comes amid the rise of generative artificial intelligence (AI), which risks our photos being manipulated and used against us. We’ve seen him in action before, from Pope Francis wearing a puffer jacket to a fake Mark Zuckerberg spouting off about how he controls the world.

One way to implement this is to use an “encoder” method which introduces complications into the information describing the position and color of pixels in an image. This alteration prevents the AI ​​from understanding what it is looking at.

The second method known as the “diffusion” attack disguises the image as another in the eyes of an AI. This is done by taking information from another target image and modifying the pixels of the source to look like this, which hides the image from the eyes of the AI.

Talk with EngadgetHeidi Salman, the paper’s lead author and a PhD student at MIT, said a “collaborative approach involving model developers, social media platforms, and policy makers presents a strong defense against unauthorized image manipulation.”

Although the techniques are effective, they are not yet infallible. A malicious actor could still reverse engineer the image by cropping it, flipping it, or adding digital noise to it.

Salman admitted that “a lot of work is needed to make this protection practical. Companies developing these models need to invest in engineering robust immunizations against the possible threats posed by these AI tools.”
