Sound-Based Authentication Challenge System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems struggle to effectively distinguish between human and automated users, leading to potential unauthorized access to computer resources. Current CAPTCHA methods, such as text-based and photo-based challenges, can be bypassed by sophisticated agents and are often frustrating for human users.
Innovation Solution
An authentication challenge system that uses sound-based challenges, where users are presented with a playback of multiple sounds and must select the correct sounds from a multiple-choice answer area, thereby requiring human auditory recognition and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If text-based or photo-based CAPTCHA methods are used, then automated access can be blocked to some extent, but these methods can be bypassed by sophisticated agents and are frustrating for human users
Solution Approach 1:
The patent replaces visual-based authentication (text/photo recognition) with auditory-based authentication (sound recognition). This substitution leverages a different human sensory capability that automated agents lack, thereby improving authentication effectiveness while maintaining ease of use for human users.
Solution Approach 2:
The patent changes the fundamental parameter of authentication from visual processing to auditory processing. By playing sounds through speakers and requiring users to identify them, the system exploits a parameter (human auditory capability) that automated agents cannot replicate, resolving the contradiction between security and user experience.
2Reliability
If sound-based challenges are used, then differentiation between human and automated users is improved, but the system complexity increases
Solution Approach 1:
The patent leverages the universal capability of human auditory processing, which all human users possess. By using sound recognition, the system creates an authentication challenge that is universally solvable by humans while remaining infeasible for automated agents, achieving high differentiation without requiring complex user-specific adaptations.
3Object-affected harmful factors
If traditional CAPTCHA methods are used, then automated scraping can be reduced, but human users experience frustration and difficulty
Solution Approach 1:
The patent substitutes visual recognition tasks with auditory recognition tasks. This replacement effectively blocks automated scraping agents that cannot process sound, while simultaneously improving user experience by providing a more intuitive and less frustrating authentication method for human users.
Data Source
AI summary
A method includes sending a challenge data structure to a user computer system. The challenge data structure defines a challenge user interface to be presented to a user of the user computer system. The challenge user interface includes a playback control area for playing an audio clip comprising a plurality of sounds. The challenge user interface prompts the user to select two or more answers corresponding to two or more sounds from a multiple choice answer area of the challenge user interface. The method includes obtaining a user input to the challenge user interface that represents a selection of at least one image from the plurality of images, and providing access to a computer resource for the user computer system based on whether the at least one image is consistent with the correct image.
