Abstract: The present specification relates to a user authentication apparatus via a document reading pattern and a control method thereof, which re-authenticate an arbitrary user using a current system via an arbitrary document reading behavior of the user and control the system based on the re-authentication result. For this, in the present specification, disclosed is a user authentication apparatus which reads an arbitrary prestored security document via an application program corresponding to the secure document and comprises a behavior observing part for extracting data corresponding to a behavior of reading the secure document; a preprocessor for removing unnecessary data from the extracted data; a feature extracting part for converting the data, filtered via the preprocessor, into document reading pattern information; and a classifier for checking an operation mode and applying a machine learning algorithm to the document reading pattern information converted in the feature extracting part when the operation mode is a registration mode.
