The urge to mine user's data in every possible way is being escalated to higher levels each day. We are, for sure, living in the data rush era.
Another interesting method for web fingerprinting explored by a team of researchers back in 2022 uses the GPU to create unique fingerprints and uses them for persistent web tracking. Codenamed 'DrawnApart' [1] and relies on WebGL to count the number and speed of the execution units in the GPU, measure the time needed to complete vertex renders, handle stall functions, and more. It uses short GLSL programs executed by the target GPU as part of the vertex shader to overcome the challenge of having random execution units handling the computations. Hence, the workload allocation is predictable and standardized.
