Narrative Authentication Using Voice Semantics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data access control systems face challenges in securing online accounts due to users' difficulty in remembering complex passwords and security questions, which can lead to compromised accounts and increased risk of unauthorized access.
Innovation Solution
A data access control technique that utilizes narrative responses to security questions, analyzed using natural language processing (NLP) to determine similarity scores, allowing for secure and memorable authentication without the need for exact repetition of responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional passwords and security questions are used for account access control, then account security is maintained, but users face difficulty in remembering complex passwords and security questions
Solution Approach 1:
The patent replaces traditional mechanical password entry systems with voice-based narrative authentication. Users record and provide voice narratives instead of typing passwords or answering security questions, substituting the mechanical typing process with voice input that is naturally more memorable and easier to provide, especially for users with typing difficulties
Solution Approach 2:
The system changes the authentication parameter from fixed-string passwords to variable narrative voice responses. By allowing natural language narratives with semantic equivalence rather than exact string matching, the system transforms the rigid password parameter into a flexible narrative parameter that users can more easily recall and provide
2Reliability
If users create accounts following service provider rules requiring numbers, symbols, and upper case characters, then account security is improved, but usernames and passwords become less personal and harder for users to remember
Solution Approach 1:
The patent replaces the mechanical process of creating complex passwords with voice-based narrative authentication. Instead of forcing users to construct passwords meeting specific character requirements, the system captures natural voice narratives that inherently satisfy security needs while being personally meaningful and easily memorable for users
3Extent of automation
If predetermined security questions are used for password reset, then automatic password resetting is enabled, but the method becomes insecure as answers may be available online or guessed by hackers
Solution Approach 1:
The patent replaces text-based security questions with voice-based narrative authentication for password reset. The voice narrative format creates more secure authentication because spoken narratives are harder to guess or obtain through online searches compared to text answers, while maintaining automatic reset capability through voice recognition and semantic analysis
Solution Approach 2:
The system combines multiple authentication factors including voice characteristics, narrative content, and semantic meaning to create a composite authentication mechanism. This multi-layered approach maintains automatic reset functionality while significantly increasing security against guessing and online information harvesting
4Measurement precision
If users are required to provide exact repetition of security question answers, then authentication precision is maintained, but users with impaired dexterity or typing skills face difficulty
Solution Approach 1:
The patent replaces the mechanical typing process with voice input for authentication. Users with impaired dexterity or typing skills can provide voice narratives that are transcribed and analyzed for semantic equivalence, eliminating the need for precise manual typing while maintaining authentication accuracy through natural language processing
5Ease of operation
If simple or repetitive passwords are used by users, then ease of remembering is improved, but account security is compromised
Solution Approach 1:
The patent replaces password-based authentication with voice narrative authentication. Users can provide personal, memorable narratives in their own words without being constrained by password complexity rules, achieving both ease of remembering and strong security because the narratives are unique to each user and harder to guess or brute-force
Data Source
AI summary
A system and method for data access control using narrative authentication questions can include a server containing a database storing login credentials for an account associated with a user, and the login credentials can include a narrative authentication question and an authentication response associated with the narrative authentication question. A system and method for data access control using narrative authentication questions can include a user device in data communication with the server, and the user device can receive and transmit user input from the user. Upon receipt of a request to access the account from the user, the server can transmit the narrative authentication question to the user device, receive a user input by the user transmitted from the user device in response to the narrative authentication question, compare the user input to the authentication response stored in the database, calculate a similarity score based on the comparison, and approve the user's request to access the account if the similarity score exceeds a threshold.
