Title: System for providing trusted user access of computer systems

Abstract: Enables trusted user access of computer systems for example that verifies trusted users and may allow trusted users to bypass challenge-response tests, while limiting access by automated processes and unwanted human challenge-response test solvers. Embodiments may implement an account that may be utilized across websites to enable a valid or trusted user to bypass challenge-response tests. Embodiments of the invention cost time, or cost a nominal fee, or require use of something that may be validated as owned by a user such as a physical address or cell phone, or trusted referral or social graph or any combination thereof, but cost large amounts time or money for spammers using cheap third world labor, thus making it expensive to invoke attacks on sites protected by embodiments of the invention.
