Jingmiao Zhang
34th USENIX Security Symposium (USENIX Security '25) · Day 3 · Privacy 2: Consent, Compliance, and Provable Privacy
In an era where speech data permeates nearly every aspect of daily life – from voice assistants and online meetings to social media and smart cars – the imperative for robust privacy protection has never been more critical. The USENIX Security talk, "SpeechGuard: Recoverable and Customizable Speech Privacy Protection," delivered by Jingmiao Zhang from the University of Science and Technology of China, introduces a pioneering system designed to address the multifaceted privacy challenges inherent in spoken information. This work stands out by not only safeguarding sensitive speech data but also by ensuring its **recoverability** for authorized parties and offering unparalleled **customizability** in access control.

Legitimate academic security research on speech privacy with a technically coherent design — multiparameter reversible warping plus CP-ABE for access control is a reasonable architecture. The work is competent but niche, and the 'first to combine all three' framing is the kind of claim that deserves more adversarial scrutiny than a conference talk typically gets.
