Researchers have developed a method to detect writing assisted by large language models (LLMs) using keystroke dynamics, particularly for Vietnamese text. Their study introduced a dataset capturing various writing modes, including paraphrasing and transcription, and simulated adversarial conditions where users attempt to evade detection. While sequential models like 1D-CNN and TypeNet showed promise, the effectiveness of keystroke analysis was found to be highly dependent on the diversity of writing behaviors modeled, with paraphrased and manipulated samples often misclassified as original.
