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”.

Visa’s Return To Syria Starts With A Test And A Bank In Lebanon

Foreign visitors will be the first users to benefit, but whether Syria’s own banks and cardholders follow is still an open question.

visa's return to syria starts with a test and a bank in lebanon

Visa is returning to Syria. Its first live international card transaction in the country was a test rather than a launch, and the milestone event ran through a Lebanese bank.

The acquirer (the bank on the merchant’s side of a card payment) was Fransabank Lebanon, with Paymera as the other named partner. Nadim Moujaes, who heads a Fransabank Group subsidiary, describes the test as both the culmination of “longstanding efforts to link Syria back to international payment networks” and “the first step in a larger path”.

“We are excited to have successfully tested live transactions today as we plan to enable international visitors to use their Visa cards while in Syria,” says Leila Serhan, Visa’s senior vice president and group country manager for the North Africa, Levant and Pakistan region. Although a significant first step, that plan doesn’t come with a hard date for when a visitor’s card will work normally.

Mohammed Safwat Raslan, governor of the Central Bank of Syria, says the test paves the way for international card acceptance in Syria and that maintaining strong compliance, risk management and operational controls will remain essential. Serhan likewise stresses that Visa has worked within applicable legal, regulatory and compliance requirements. For a test transaction, it seems there was a great deal of attention paid to the rules, with the entire operation being carefully managed.

The test is the latest step in a sequence that began in December 2025, when Visa announced a strategic roadmap to support Syria’s integration into the global digital economy. In February 2026 it hosted its first industry gathering of banks, ecosystem partners and policymakers in Damascus and, the same month, signed an agreement with Syria’s Ministry of Communications and Information Technology in San Francisco.

Michel Kattouah, Paymera’s CEO, called the test “the return of international card acceptance,” but while that’s positive news, there’s no word yet on when a Syrian bank will issue a Visa card to a Syrian customer.
