System and Method for Delivering a Human Interactive Proof to the Visually Impaired by Means of Semantic Association of Objects

摘要

A system and method for delivering a Human Interactive Proof, or reverse Turing test to the visually impaired; said test comprising a method for restricting access to a computer system, resource, or network to live persons, and for preventing the execution of automated scripts via an interface intended for human interaction.;When queried for access to a protected resource, the system will respond with a challenge requiring unknown petitioners to solve an auditory puzzle before proceeding, said puzzle consisting of an audio waveform representative of the names or descriptions of a collection of apparently random objects.;The subject of the test must either recognize a semantic or symbolic association between two or more objects, or isolate an object that does not belong with the others, indicating their selection by typing the name of the object with their keyboard.
