摘要

A manipulable human interactive proof (HIP) displays at most a portion of verification information. A user performs at least one manipulation on the HIP display to obtain full verification information.

1. A computing device comprising:
one or more hardware processors; one or more computer-readable storage device storing instructions, which when executed by the one or more hardware processors, causes the one or more hardware processors to: receive a manipulable object including a group of images arranged as a conglomeration of 3-D characters in contact with one another, the manipulable object being configured to rotate around an axis of rotation, the manipulable object formed by merging recognizable characters with one or more bogus characters; display a first subset of information as part of a human interactive proof (HIP) in response to an attempt by a client to access one or more services; display a second subset of information following one or more manipulations of the manipulable object, the first subset of information and the second subset of information comprising verification information of the client; receive a user input corresponding to the verification information of the client; and compare the user input with an interactive solution corresponding to the manipulable object for determining whether to grant the client access to the one or more services.
