Latest Patents

Trujillo holds a patent for "User-agent anomaly detection using sentence embedding." This patent describes systems and methods for detecting anomalies in user-agent strings. In one embodiment, a user-agent string is embedded into a numerical data vector representation using a sentence embedding algorithm, such as FastText. A predictive score is calculated based on this numerical data vector representation, utilizing a probability distribution function model that assesses the likelihood of occurrence of the observed user-agent based on patterns learned from historic payload data. The predictive score is then compared to a threshold to determine if the user-agent is fraudulent.
