This document outlines a proposed system to defend against automated password guessing attacks using Turing tests. It begins with an objective to implement a system using Turing tests to prevent password guessing. It then reviews existing techniques, including Pinkas and Sander's original approach, a modified version, and Van Oorschot and Stubblebine's approach. The proposed system aims to identify trusted systems based on IP address and MAC address rather than cookies. It would allow unlimited attempts for legitimate users and impose Turing tests after 3 attempts for untrusted systems. Diagrams depict the system modules, use cases, and activities. Advantages include preventing cookie theft attacks while not affecting legitimate users. Future work could focus on preventing keyloggers and remote
