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”.

lebanon ministers meet visa over national digital payment platform

Lebanon’s finance and technology ministers met representatives from Visa last week to discuss a proposed unified national digital payment platform for government services, according to a readout from the Ministry of Finance.

The meeting brought together Finance Minister Yassin Jaber, Minister of State for Technology and Artificial Intelligence Kamal Shehadeh, a Visa delegation, and experts from both ministries. Discussion focused on whether Lebanon could establish a single platform through which citizens and institutions would pay taxes, fees, fines and other official transactions electronically, using mobile phones and other digital channels.

The Visa delegation presented examples from countries that have adopted unified government payment platforms, including the United Arab Emirates, Singapore, Estonia and Jordan. According to the readout, the examples were presented as having increased collection rates and expanded financial inclusion.

Talks covered settlement mechanisms, direct transfer to the treasury account, financial reconciliation, risk management, cybersecurity, fees, and an operational model that would involve the private sector. The parties agreed to continue technical and institutional consultations, prepare a comparative study, and develop an implementation roadmap before any decision on adopting a model for Lebanon.

Jaber said the Ministry of Finance had already enabled citizens to pay using credit cards and e-wallets through transfer companies, but described the proposed platform as a further step. He framed the development of electronic payment and collection systems as a priority within the ministry’s modernization plan.

Shehadeh outlined the citizen-facing concept as a single mobile application through which users could settle obligations to ministries, government institutions and other bodies.

“The idea, in short, is that any citizen downloads an application on their mobile phone, through which they can pay all service obligations for all ministries, government institutions, or those owned by the Lebanese state, and others as well, as the platform is not limited only to state institutions,” he said.

Shehadeh added that the platform would not displace banks and money transfer companies that currently provide collection services to the state, calling it complementary to their work.
