Deepfake voice attacksThese attacks are causing a stir in the technology world, and they pose a new challenge to detection systems. It’s time to test the biometric software companies, as real-world attacks are becoming more common. This article explores the recent incidents, the responses of biometric software firms and researchers, as well as the future of deepfake detectors.
Recently, we’ve seen an increase in the use deepfake voice technologies, causing great controversy in the worlds of technology. The ability to imitate voices to an almost perfect degree has raised concerns, especially in disinformation. This has put Biometric software companiesResearchers who claim to be able to detect deepfake voices are put to the ultimate test.
In a recent incident, robocalls were sent in the United States as part a disinformation strategy, purporting that they were President Joe Biden. The voice message sounded like Biden telling people to not vote in a primaries election. It is possible that the voice was generated by an artificial intelligence system. This incident has called into question the capabilities of deepfake software, as there was no consensus on the authenticity of this voice.
“Deepfake technologies force us to question the validity of what we hear. This challenge puts detection technologies to their ultimate test.”
One company that is making strides on the field is ID R&D, a division of Mitek. In response to a second major voice cloning controversy involving pop singer Taylor Swift, the company demonstrated through a video its voice biometrics code’s ability of separating actual recordings from digital imitations. The fake Biden voice used in the attempt to commit electoral fraud poses a unique challenge.
Deepfake detection: An uncertain field
Bloomberg ArticleWe examined the possibility that the Biden call was the first example of a deepfake dirty audio trick. No one was able to confirm if it was the work of an actor or AI. ElevenLabs’ and Clarity’s detectors had different opinions. Clarity’s software, while ElevenLabs found that it was unlikely that the misinformation attacks were a result of biometric fraud.
Crunchbase says that ElevenLabs – a company specializing in creating voices – recently achieved unicorn status after raising an $80M series B. This raised the company’s value to more than $1B.
Hope in Research
Despite the uncertainties and challenges, research gives hope. A team of students and alumni from the University of California – Berkeley believe they have developed a detection method that functions with little to no errors. This method involves feeding a deep-learning algorithm raw audio for it to process and extract multidimensional representations. These representations are then used to separate authentic voices from fakes. This method has not yet been tested outside a laboratory setting. The research team believes that the technique requires “proper context” in order to be fully understood.
As deepfake technology continues to evolve, it is becoming more and more important to develop detection methods. These real-world tests will shape the future of these technologies. The future of deepfake detectors.
