ID R&D patents voice biometrics and parody detection to protect smart devices

ID R&D has obtained a patent for integrated voice biometrics and parody detection for keywords and short requests used to unlock and access mobile phones, smart devices and IoT devices to protect them against fraud carried out using generative artificial intelligence.

The company notes in the announcement that the use of voice as an interface for smart and IoT devices is expected to grow at a compound annual rate of 21.3% from last year through 2030. Advances in large language models (LLM) are contributing to this growth ), However, according to the announcement, the FTC notes that it also contributes to fraud.

The United States Patent and Trademark Office has granted a patent for a “Method and apparatus for unlocking a user’s device by voice.”

The patent document describes advanced neural networks that adapt to the unique biometric characteristics of a user’s voice, as well as detecting whether a voice sample is real or fake, in what the patent calls “anti-spoofing authentication.” This process can include fast Fourier transform and discrete cosine transform functions to generate three different assurance scores that contribute to the overall anti-counterfeit assurance score.

“As a founder and veteran of biometrics, I realize that innovative technology is crucial to improving the user experience and providing solid protection against fraud and unauthorized access, especially in the voice domain,” says Alexey Khitrov, president of ID R&D. “By leveraging the inherent simplicity of voice control, we provide secure access across multiple devices, including smartphones, desktop computers and smart home systems. This positions ID R&D as a leader in voice security innovation.”

ID R&D is increasingly focused on detecting biometric presentation attacks, injection attacks and deepfakes, analyzing the famous recent voice fraud case and co-hosting an upcoming free webinar with Biometric update on video injection.
