Word-List Authentication Mapping for Voice-Friendly User Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods relying on complex numeric or alphanumeric references, such as account numbers and passwords, are challenging for users to remember and result in increased computational burden and customer frustration, especially in voice-based interactions.
Innovation Solution
Utilizing an ordered word list (OWL) as a memorable identifier, processed through speech or text recognition, which is converted into an identification number and validated by a third-party system without altering existing customer information systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex numeric or alphanumeric references (account numbers, passwords) are used for authentication, then security is maintained, but user memorability and ease of operation deteriorate
Solution Approach 1:
The patent introduces an intermediary service that translates between memorable word-based identifiers and internal numeric/account references. Users interact with the system using natural language words they can easily remember, while the intermediary handles the conversion to secure internal identifiers, thus resolving the contradiction between security and memorability.
Solution Approach 2:
The system changes the parameter of authentication from numeric/alphanumeric references to word-based identifiers. By transforming the authentication input from hard-to-remember numbers to easy-to-remember words, the system maintains security through the intermediary translation layer while significantly improving user memorability and ease of operation.
2Reliability
If long numeric or alphanumeric references are used as identifiers, then unique identification is achieved, but user experience and engagement deteriorate
Solution Approach 1:
The intermediary service acts as a bridge between the user-friendly word-based input and the system's internal long numeric references. This allows the system to maintain unique identification through its existing numeric reference structure while providing users with an engaging, simple word-based interaction experience.
Solution Approach 2:
The system creates a copy or mapping between word-based identifiers and numeric references. Instead of requiring users to directly handle long numeric strings, the system maintains both representations, allowing users to interact with simplified word copies while the original numeric references ensure unique identification.
3Ease of operation
If speech recognition is used to process user input, then voice-based authentication is enabled, but recognition accuracy may deteriorate with complex identifiers
Solution Approach 1:
The system changes the parameter of speech recognition input from complex numeric strings to simple word-based identifiers. Words are naturally easier for speech recognition systems to accurately transcribe and interpret, thereby improving recognition accuracy while maintaining voice-based authentication capabilities.
4Productivity
If automated authentication procedures are used, then efficiency is improved, but customer satisfaction deteriorates when authentication fails
Solution Approach 1:
By changing the authentication parameter from complex numeric codes to simple words, the system maintains high automated processing efficiency while significantly improving the success rate. Users can easily provide correct word-based identifiers, reducing authentication failures and the need for manual intervention.

AI summary
A method of authenticating a user to a third party using a computing device is disclosed, the method comprising: receiving an input comprising one or more words from the user; obtaining an identification number corresponding to the one or more words; transmitting the identification number to a third party device associated with the third party; and receiving a message from the third party device that indicates whether or not the identification number corresponds to a valid identity. A suitable system and computer program for implementing the method are also disclosed.
