Protecting payments in an era of deepfakes and advanced AI


In the midst of unprecedented volumes of e-commerce since 2020, the number of digital payments made every day around the planet has exploded – hitting about $6.6 trillion in value last year, a 40 percent jump in two years. With all that money flowing through the world's payments rails, there's even more reason for cybercriminals to innovate ways to nab it. To help ensure payments security today requires advanced game theory skills to outthink and outmaneuver highly sophisticated criminal networks that are on track to steal up to $10.5 trillion in "booty" via cybersecurity damages, according to a recent Argus Research report. Payment processors around the globe are constantly playing against fraudsters and improving upon "their game" to protect customers' money. The target invariably moves, and scammers become ever more sophisticated.

Are You Better Than a Machine at Spotting a Deepfake?


Sarah Vitak: This is Scientific American's 60 Second Science. Early last year a TikTok of Tom Cruise doing a magic trick went viral. I mean, it's all the real thing."] Matt Groh: A deepfake is a video where an individual's face has been altered by a neural network to make an individual do or say something that the individual has not done or said. Vitak: That is Matt Groh, a Ph.D. student and researcher at the M.I.T. Media Lab. Groh: It seems like there's a lot of anxiety and a lot of worry about deepfakes and our inability to, you know, know the difference between real or fake. Vitak: But he points out that the videos posted on the Deep Tom Cruise account aren't your standard deepfakes. The creator, Chris Umé, went back and edited individual frames by hand to remove any mistakes or flaws left behind by the algorithm. It takes him about 24 hours of work for each 30-second clip. It makes the videos look eerily realistic. But without that human touch, a lot of flaws show up in ...

Singaporean wins $100k prize in challenge to build AI models that detect deepfakes


SINGAPORE - A one-man team comprising Singaporean research scientist Wang Weimin beat 469 other teams from around the world in a five-month-long challenge to develop the best artificial intelligence (AI) model for detecting deepfakes, or digitally altered video clips. Mr Wang's model was 98.53 per cent accurate at telling apart genuine clips from those that featured digitally manipulated faces, voices or both. On Friday (April 29), the National University of Singapore graduate was awarded first place and a cash prize of $100,000 in the Trusted Media Challenge organised by AI Singapore, a national AI programme office under the National Research Foundation. Mr Wang, who works at Chinese tech giant ByteDance, which owns TikTok, was also offered a $300,000 start-up grant to commercialise his invention. But he said he is hoping to incorporate his AI model into his company's BytePlus platform and offer deepfake detection as a service to its clients.

3 Positive Use Cases of Deepfakes


The negative applications of deepfakes can be controlled through blockchain and other deep learning-based image forgery detection tools. However, there is more to deepfakes than just negative applications. Ever since the emergence of deepfakes, they have been normally associated with pranks or cybercrimes. Accordingly, there are several pieces that discuss the ways in which deepfake-related problems can be resolved through blockchain or deep learning-based image forgery detection. The concept of deepfakes, also known as synthetic media, is one of the more irreverent applications of AI and computer vision.

Deepfakes are now trying to change the course of war


In the third week of Russia's war in Ukraine, Volodymyr Zelensky appeared in a video, dressed in a dark green shirt, speaking slowly and deliberately while standing behind a white presidential podium featuring his country's coat of arms. Except for his head, the Ukrainian president's body barely moved as he spoke. His voice sounded distorted and almost gravelly as he appeared to tell Ukrainians to surrender to Russia. "I ask you to lay down your weapons and go back to your families," he appeared to say in Ukrainian in the clip, which was quickly identified as a deepfake. "This war is not worth dying for. I suggest you to keep on living, and I am going to do the same."

The Download: Russia is risking the creation of a "splinternet"--and it could be irreversible

MIT Technology Review

The big picture: Psychedelic drugs have long been touted as possible treatments for mental-health disorders like depression and PTSD. But very little is really known about what these substances actually do to our brains. Understanding how they work could help unlock their potential. A new methodology: Some scientists are using AI to figure it out. A team at McGill University in Montreal used natural language processing to study written "trip reports" of users' experiences with a range of drugs.

This is How I Deep Faked Myself At Every Office Meeting


We've all experienced those interminable, necessary post-pandemic Zoom calls where time appears to stand still, and everything wonderful about a writer's everyday life crumbles to dust. Fortunately, some of us have had better times. Despite the fact that I usually have a good time at meetings, I decided to add some AI to the mix. I thought about how I might make a meeting more enjoyable. How can something so drab and uninteresting be transformed into a rainbow of laughter and delight?

Deepfakes Can Help Families Mourn--or Exploit Their Grief


We now have the ability to reanimate the dead. Improvements in machine learning over the past decade have given us the ability to break through the fossilized past and see our dearly departed as they once were: talking, moving, smiling, laughing. Though deepfake tools have been around for some time, they've become increasingly available to the general public in recent years, thanks to products like Deep Nostalgia--developed by ancestry site My Heritage--that allow the average person to breathe life back into those they've lost. Despite their increased accessibility, these technologies generate controversy whenever they're used, with critics deeming the moving images--so lifelike yet void of life--"disturbing," "creepy," and "admittedly queasy." In 2020, when Kanye got Kim a hologram of her late father for her birthday, writers quickly decried the gift as a move out of Black Mirror.
