PIN PIN INPUT METHOD AND SYSTEM BASED ON USER BEHAVIOR RECOGNITION USING MACHINE LEARNING

摘要

Disclosed are a method and a system for inputting a PIN based on user behavior recognition using machine learning. According to one embodiment of the present invention, a user authentication method comprises the steps of: displaying an authentication screen for user authentication on an electronic device; receiving input information including password data inputted from a user through the authentication screen, time data related to the password data, and position data related to the password data; and performing user authentication through the comparison of the learned learning data based on the input information and input information inputted from the user.
