London-based startup Surf Security on Wednesday announced the launch of a deepfake detection tool that is integrated into its enterprise web browser.
Surf’s Enterprise Zero-Trust Browser is a security-focused browser that provides data leakage prevention, download protection, anti-social engineering, and access control capabilities.
The latest addition to the browser — currently available in beta — is called Deepwater, a built-in deepfake detector that, according to Surf, has a 98% accuracy.
Voice and video deepfakes are increasingly used by threat actors, including to lure users to scams, conduct phishing attacks, and to steal money from companies.
Surf says its new deepfake detection tool makes it easier to detect fake audio and video directly within the browser, including in communications over applications such as Zoom, Slack, Microsoft Teams, Google Chat and WhatsApp.
Users simply need to press a button and they are told if the content they are seeing on their screen is genuine or generated by AI.
The deepfake detection technology leverages a neural network trained on a vast database of deepfakes, enabling it to accurately distinguish between human and AI-generated voices.
The tool also includes a background noise reduction feature that enables it to analyze even recordings from noisy environments, which could be more difficult to assess.
Surf says its tool runs on technologies such as State Space Models, which can detect deepfakes across languages and accents by modeling probabilistic relationships between audio frames to show inconsistencies, which allows for high speed and accuracy, even with very short audio clips.
Surf Security also plans on adding AI image detection to its enterprise browser in the future.
Surf was launched in 2022 and to date it has raised a significant seed round, but would not disclose the exact amount.
