With the release of ChatGPT, I’ve read many random articles about this or that threat from the technology. This paper is a good survey of the field: what the threats are, how we might detect machine-generated text, directions for future research. It’s a solid grounding amongst all of the hype. Machine Generated Text: A Comprehensive … Read More “Threats of Machine-Generated Text” »

Breaking RSA with a Quantum Computer

A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong. We have long known from Shor’s algorithm that factoring with a quantum computer is easy. But it … Read More “Breaking RSA with a Quantum Computer” »

Yet another smartphone side-channel attack: “EarSpy: Spying Caller Speech and Identity through Tiny Vibrations of Smartphone Ear Speakers“: Abstract: Eavesdropping from the user’s smartphone is a well-known threat to the user’s safety and privacy. Existing studies show that loudspeaker reverberation can inject speech into motion sensor readings, leading to speech eavesdropping. While more devastating attacks … Read More “Recovering Smartphone Voice from the Accelerometer” »

The Decoupling Principle

academic papers, anonymity, authentication, privacy, pseudonymity, Security technology, Uncategorized

This is a really interesting paper that discusses what the authors call the Decoupling Principle: The idea is simple, yet previously not clearly articulated: to ensure privacy, information should be divided architecturally and institutionally such that each entity has only the information they need to perform their relevant function. Architectural decoupling entails splitting functionality for … Read More “The Decoupling Principle” »

This technique measures device response time to determine distance: The scientists tested the exploit by modifying an off-the-shelf drone to create a flying scanning device, the Wi-Peep. The robotic aircraft sends several messages to each device as it flies around, establishing the positions of devices in each room. A thief using the drone could find … Read More “Using Wi-FI to See through Walls” »

Adversarial ML Attack that Secretly Gives a Language Model a Point of View

Machine learning security is extraordinarily difficult because the attacks are so varied—and it seems that each new one is weirder than the next. Here’s the latest: a training-time attack that forces the model to exhibit a point of view: Spinning Language Models: Risks of Propaganda-As-A-Service and Countermeasures.” Abstract: We investigate a new threat to neural … Read More “Adversarial ML Attack that Secretly Gives a Language Model a Point of View” »

Interesting research: “ImpNet: Imperceptible and blackbox-undetectable backdoors in compiled neural networks, by Tim Clifford, Ilia Shumailov, Yiren Zhao, Ross Anderson, and Robert Mullins: Abstract: Early backdoor attacks against machine learning set off an arms race in attack and defence development. Defences have since appeared demonstrating some ability to detect backdoors in models or even remove … Read More “Inserting a Backdoor into a Machine-Learning System” »

Detecting Deepfake Audio by Modeling the Human Acoustic Tract

Posted on By infossl
academic papers, artificial intelligence, deep fake, Security technology, Uncategorized

This is interesting research: In this paper, we develop a new mechanism for detecting audio deepfakes using techniques from the field of articulatory phonetics. Specifically, we apply fluid dynamics to estimate the arrangement of the human vocal tract during speech generation and show that deepfakes often model impossible or highly-unlikely anatomical arrangements. When parameterized to … Read More “Detecting Deepfake Audio by Modeling the Human Acoustic Tract” »

Depending on where you are when you download your Android apps, it might collect more or less data about you. The apps we downloaded from Google Play also showed differences based on country in their security and privacy capabilities. One hundred twenty-seven apps varied in what the apps were allowed to access on users’ mobile … Read More “Differences in App Security/Privacy Based on Country” »

Okay, it’s an obscure threat. But people are researching it: Our models and experimental results in a controlled lab setting show it is possible to reconstruct and recognize with over 75 percent accuracy on-screen texts that have heights as small as 10 mm with a 720p webcam.” That corresponds to 28 pt, a font size … Read More “Leaking Screen Information on Zoom Calls through Reflections in Eyeglasses” »
