Developer alleges Alibaba uses audio fingerprinting for web tracking

SCM feed for Latest

Matt Callaghan, a software engineer, has raised concerns that Alibaba's website may be using audio fingerprinting techniques for tracking users. He found that the site employs obfuscated audio scripts that create a waveform and analyze its output, which could allow the company to monitor user behavior in a way that bypasses traditional tracking methods. This discovery raises significant privacy issues, as it suggests that users may be unwittingly tracked through audio signals emitted from their devices. The implications are serious, especially for individuals who value their privacy online. The use of such techniques could lead to increased scrutiny from regulators and may prompt users to reconsider their interactions with the site.
