Abstract:
1. A method of controlling access to a system, comprising: generating a challenge to a user of the system, wherein the challenge includes a plurality of parts including: prompting the user to solve the challenge including the verify part of the challenge and the read part of the challenge without identifying to the user which of the parts is the verify part and which of the parts is the read part; receiving input from the user; determining if the input from the user relative to the verify part of the challenge corresponds with the known answer for the verify part of the challenge; identifying the input from the user relative to the read part of the challenge as an answer to the read part of the challenge, if the input from the user relative to the verify part of the challenge corresponds with the known answer for the verify part of the challenge; and allowing the user to access the computer system if the input from the user relative to the verify part of the challenge corresponds with known answer for the verify part of the challenge and without determining if the input from the user relative to the read part of the challenge is correct.
