摘要： One embodiment of the invention is a method utilizing a CAPTCHA to generate a human likeness score including blocks: a) receiving a user solution to the CAPTCHA; b) receiving a user interaction pattern descriptive of an interaction undertaken by the user, through a graphical interface of the CAPTCHA, to achieve the user solution; c) determining the accuracy of the user solution; d) comparing the user interaction pattern against an interaction model generated from interaction patterns of previous users; e) calculating the human likeness score based upon the determination of block c) and the comparison of block d), wherein the human likeness score lies within a continuum of human likeness scores.

摘要： A method for determining whether a user is a human is disclosed. The method includes receiving a request to determine whether a user attempting to access a service provided by a host compute device is a human, obtaining an input motion that the user entered while the user solved a challenge-response test for accessing the service, extracting a noise component of the input motion, retrieving a noise model characterizing noise patterns of input motions previously entered into graphical user interfaces by humans, comparing the noise component with the noise model, calculating a human likeness score of the user based on the comparison, determining whether the user is a human based on the human likeness score, and sending a result of the determination to the host compute device such that the host compute device can allow or restrict access to the service by the user depending on the result.
