Voice-Controlled Password Submission via Audio Candidate Ranking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when repeatedly entering passwords for network access, especially in password-protected wireless networks, as existing technologies lack efficient methods to accurately and reliably submit candidate passwords for successful connection.
Innovation Solution
A voice-controlled computing device that captures audio input from users, performs speech recognition to identify a list of candidate passwords with varying probabilities, and submits them sequentially until access is granted, thereby reducing the need for repeated user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition is used to identify candidate passwords from audio input, then the ease of operation is improved, but the reliability of password submission deteriorates due to inaccurate recognition
Solution Approach 1:
The system performs preliminary speech recognition to generate multiple candidate passwords before the actual authentication attempt. By pre-processing the audio input and creating a ranked list of possible passwords, the system prepares multiple options in advance, allowing the most likely correct password to be submitted first while having backups ready if the initial attempt fails.
Solution Approach 2:
The system dynamically adjusts the password submission process by ranking candidate passwords based on recognition confidence scores and submitting them in order of likelihood. The system adapts to the quality of audio input and user speech patterns, flexibly selecting from multiple candidates rather than relying on a single static recognition result. This dynamic approach allows the system to handle varying recognition accuracies effectively.
2Reliability
If multiple candidate passwords are submitted sequentially, then the reliability of access is improved, but the loss of time increases due to multiple submission attempts
Solution Approach 1:
The system performs preliminary ranking and scoring of candidate passwords before submission. By pre-calculating confidence scores and establishing a ranked order of candidates based on speech recognition accuracy, the system ensures that the most likely correct password is submitted first. This preliminary organization minimizes the expected number of submission attempts, reducing time loss while maintaining high reliability.
Solution Approach 2:
The system autonomously manages the password submission process without requiring user intervention. It automatically submits candidate passwords in ranked order, monitors authentication results, and proceeds to the next candidate if needed. This self-service capability eliminates delays caused by user re-entry and allows rapid sequential submission of multiple candidates, optimizing the balance between reliability and time efficiency.
Data Source
AI summary
A computing device configured to request a password from a user, capture audio after issuing the request, and determine a number of alternative candidate passwords most likely represented by the audio. After identifying the number of candidate passwords, the computing device may submit these candidate passwords, one at a time, to an entity until the entity grants the device access to an account associated with the user or until the device has submitted each candidate password. The account may comprise a network account (e.g., a wired or wireless network account), an online account (e.g., an email account, an account an online merchant, etc.), or the like.
