By introducing slight distortions or perturbations in the audio signal, AntiFake effectively ‘tricks’ AI systems. These alterations are imperceptible to human listeners but significantly disrupt AI’s ability to accurately analyze and replicate the voice. This technique ensures that any attempt by AI to generate a deepfake from an AntiFake-protected voice recording results in an output that is markedly different from the original voice, thereby safeguarding the user’s unique vocal identity.

Signal Scrambling

The core of AntiFake’s functionality lies in its ability to scramble the voice signal. This scrambling is done in a way that maintains the natural sound of the voice to human ears while rendering it unrecognizable to AI systems. When an AI attempts to clone a voice that has been scrambled by AntiFake, it struggles to produce a clean and accurate replica. This is because the AI cannot effectively interpret the altered characteristics of the scrambled voice, which are crucial for generating a convincing deepfake. This method serves as a proactive barrier, preventing the creation of deepfakes at their source rather than merely detecting them after they have been made.

Ensuring Voice Authenticity

To ensure the authenticity of a voice, AntiFake incorporates a sophisticated system of voice biometrics analysis. It extracts over 1300 voice biomarkers from recordings, which include tone, pitch, cadence, and pronunciation patterns. These biomarkers form a unique voiceprint, as distinctive as a fingerprint. AntiFake’s deep neural networks are trained on an extensive dataset of synthesized fake voices produced by the latest voice cloning and deepfake algorithms. This training enables the AI to differentiate between authentic and AI-generated voices effectively. When an audio file is processed through AntiFake, the AI compares the voice biometrics against the owner’s registered voiceprint and known fake voice patterns, assigning a confidence score that indicates the likelihood of the voice being spoofed.

How AntiFake Safeguards Voice Identity from Deepfakes？
