Chinese retailer AliExpress has been found to use a tracking method known as browser fingerprinting, which involves sending inaudible sounds to users’ browsers. This discovery was made by researcher Matthew Callaghan when he noticed that audio from his Bluetooth headphones stopped while browsing the AliExpress homepage. His headphones, designed to connect to multiple devices, would resume normal operation once the AliExpress tab was closed. Upon investigation, Callaghan identified two complex scripts that generated a graph analyzing the WebAudio readings of each visiting browser, effectively employing audio output to track users without their consent.
Why It Matters
Browser fingerprinting is a technique that raises significant privacy concerns as it allows companies to track users without their explicit knowledge. Historically, such methods have been criticized for infringing on user privacy, particularly as regulations around data protection become more stringent worldwide. The use of inaudible sound waves to gather data is an example of how some companies may exploit technology to circumvent traditional privacy measures. As digital tracking methods evolve, the potential for misuse increases, prompting calls for clearer regulations and more robust data protection practices.
