System and Method for Detecting and Preventing Automated Interaction Based on Detected Actions Performed by User to Solve a Proffered Puzzle

摘要

A system and method is provided to detect and prevent automated interaction. A server sends a puzzle to a client application of a client device. The puzzle is programmed and configured to enable a user to solve the puzzle with doing one or a series of maneuvers only using an input pointing means and by moving an Actor object displayed in the puzzle along an indicated path to a target location on the path. The server receives from the client application behavior data documenting the user's interactions with the Actor object in the course of trying to solve the puzzle, analyzes the received user behavior data, and decides whether the puzzle is solved and is solved by a human based on the analysis on the behavior data. The server sends to the client application an authentication token when the server decides that the puzzle is solved by a human.
