Assocaptcha: designing human-friendly secure captchas using word associations
Pages 3705 - 3710
Abstract
CAPTCHAs are challenge-response tests to verify that the user is a human (and not a program/robot). CAPTCHAs use problems that are trivial for humans to solve, but are hard for computers. Unfortunately, CAPTCHAs have focused only on one aspect of human ability: image/word recognition. This paper explores the usage of other human abilities: particularly, finding associations between related concepts; to design secure, human-friendly Human Interaction Proofs (HIPs)
In this paper, we present AssoCAPTCHA: CAPTCHAs so designed that they require no greater user-interaction than conventional solutions, yet have orders of magnitude greater security. Preliminary tests confirm user acceptance and efficiency of the system.
