Researchers have demonstrated a method to create “master faces,” computer generated faces that act like master keys for facial recognition systems, and can impersonate several identities with what the researchers claim is a high probability of success.
In their paper, researchers at the Blavatnik School of Computer Science and the School of Electrical Engineering in Tel Aviv detail how they successfully created nine “master key” faces that are able to impersonate almost half the faces in a dataset of three leading face recognition systems. The researchers say their results show these master faces can successfully impersonate over 40 percent of the population in these systems without any additional information or data of the person they are identifying.

Generating Master Faces for Dictionary Attacks with a Network-Assisted Latent Space Evolution
A master face is a face image that passes face based identity-authentication for a large portion of the population. These faces can be used to impersonate, with a high probability of success, any user, without having access to
any user-information. We optimize these faces, by using an evolutionary algorithm in the latent embedding space of the StyleGAN face generator. Multiple evolutionary strategies are compared, and we propose a novel approach that employs a neural network in order to direct the search in the direction of promising samples, without adding fitness evaluations. The results we present demonstrate that it is possible to obtain a high coverage of the population (over 40%) with less than 10 master faces, for three leading deep face recognition systems.

Lucasfilm hires YouTuber who used deepfake to improve ‘The Mandalorian’
Luke Skywalker’s CGI face in the character’s The Mandalorian cameo was met with a lot of criticism, and fans even tried to fix the scene with various tools and programs. One of those fans did so well, Lucasfilm has hired him to help it ensure its upcoming projects won’t feature underwhelming de-aging and facial visual effects. That fan is a YouTuber known as Shamook, who uses deepfake technology to improve upon bad CG effects and to put actors in shows and movies they never starred in. Read More
Holly Herndon’s AI Deepfake “Twin” Holly+ Transforms Any Song Into a Holly Herndon Song
“Vocal deepfakes are here to stay. A balance needs to be found between protecting artists, and encouraging people to experiment with a new and exciting technology.”
Holly Herndon, a prominent voice on the cross-section between AI and the music industry who has prominently used AI in her music, has released a new voice instrument: her AI deepfake “twin,” Holly+. It’s a website where you can upload any polyphonic audio and have it transformed into a download of music sung in Herndon’s voice. Give it a try here and read more details on how it works here.

Facebook develops new method to reverse-engineer deepfakes and track their source
Deepfakes aren’t a big problem on Facebook right now, but the company continues to fund research into the technology to guard against future threats. Its latest work is a collaboration with academics from Michigan State University (MSU), with the combined team creating a method to reverse-engineer deepfakes: analyzing AI-generated imagery to reveal identifying characteristics of the machine learning model that created it.
The work is useful as it could help Facebook track down bad actors spreading deepfakes on its various social networks. This content might include misinformation but also non-consensual pornography — a depressingly common application of deepfake technology. Right now, the work is still in the research stage and isn’t ready to be deployed. Read More
These creepy fake humans herald a new age in AI
Need more data for deep learning? Synthetic data companies will make it for you.
You can see the faint stubble coming in on his upper lip, the wrinkles on his forehead, the blemishes on his skin. He isn’t a real person, but he’s meant to mimic one—as are the hundreds of thousands of others made by Datagen, a company that sells fake, simulated humans.
These humans are not gaming avatars or animated characters for movies. They are synthetic data designed to feed the growing appetite of deep-learning algorithms. Firms like Datagen offer a compelling alternative to the expensive and time-consuming process of gathering real-world data. They will make it for you: how you want it, when you want—and relatively cheaply. Read More
Cybersecurity researchers build a better ‘canary trap’
A new artificial intelligence system generates fake docs to fool adversaries
The “canary trap” technique in espionage spreads multiple versions of false documents to conceal a secret. Canary traps can be used to sniff out information leaks, or as in WWII, to create distractions that hide valuable information.
WE-FORGE, a new data protection system designed at Dartmouth’s Department of Computer Science, uses artificial intelligence to build on the canary trap concept. The system automatically creates false documents to protect intellectual property such as drug design and military technology. Read More
Truth, Lies, and Automation
HOW LANGUAGE MODELS COULD CHANGE DISINFORMATION
A new Georgetown Center for Security and Emerging Technology report examines how OpenAI’s language model GPT-3 could generate content for disinformation campaigns., finding that should adversaries choose to pursue automation in their disinformation campaigns, we believe that deploying an algorithm like the one in GPT-3 is well within the capacity of foreign governments, especially tech-savvy ones such as China and Russia. It will be harder, but almost certainly possible, for these governments to harness the required computational power to train and run such a system, should they desire to do so. Read More
This AI Makes Robert De Niro Perform Lines in Flawless German
When films are dubbed in another language, an actor’s facial movements may clash with his lines. Technology related to deepfakes can help smooth things over.
You talkin’ to me … in German?
New deepfake technology allows Robert De Niro to deliver his famous line from Taxi Driver in flawless German—with realistic lip movements and facial expressions. The AI software manipulates an actor’s lips and facial expressions to make them convincingly match the speech of someone speaking the same lines in a different language. The artificial-intelligence-based tech could reshape the movie industry, in both alluring and troubling ways. Read More
Why ‘deepfake geography’ presents significant risks — and how researchers are detecting it
“Seeing is believing.” It’s an aphorism that used to be a lot more true than it is today, now that computers can easily produce all manner of fake images and altered recordings. Many of us have seen the photos of celebrities who don’t exist and videos of lip-synching politicians. These “deepfakes” have raised real concerns about what is and isn’t true in our newsfeeds and other media.
This problem even extends to the maps and satellite images that represent our world. Techniques such as “location spoofing” and deepfake geography present significant risks for our increasingly connected society.br>
Because of this, a team of researchers at University of Washington are working to identify ways to detect these fakes, as well as proposing the creation of a geographic fact-checking system. Read More
