Abstract:
Systems and methods are provided for authentication by combining a Reverse Turing Test (RTT) with password-based user authentication protocols to provide improved resistance to brute force attacks. In accordance with one embodiment of the invention, a method is provided for user authentication, the method including receiving a username/password pair associated with a user; requesting one or more responses to a first Reverse Turing Test (RTT); and granting access to the user if a valid response to the first RTT is received and the username/password pair is valid.

Claim (Index 26):
The method of  claim 19 , wherein the method further comprises determining that one or more valid responses to a prior RTT have not been previously provided to the system and wherein requesting one or more responses to the RTT is further in response to determining that one or more valid responses to a prior RTT have not been previously provided to the system.
