Audio Security Code Delivery for Mobile Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-factor authorization systems face inefficiencies when users cannot immediately access a secondary device for security codes, leading to delayed authentication and potential expiration of codes, causing authorization failures.
Innovation Solution
The system outputs an audio representation of the security code if the user does not access it within a predefined time, using a first device to determine if a second device is within range for audio delivery, eliminating the need for physical access and reducing expiration risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security code is sent via SMS to a secondary device, then the authorization security is improved, but the authorization time increases and the code may expire before the user can access it
Solution Approach 1:
The patent introduces an intermediary audio output mechanism that mediates between the SMS security code delivery and the user's access. Instead of requiring direct physical access to the SMS message on the secondary device, the system uses audio synthesis as an intermediary channel to deliver the security code information to the user, thereby reducing access time while maintaining security through the original SMS delivery mechanism
Solution Approach 2:
The patent replaces the mechanical interaction of physically accessing and reading the SMS message on the secondary device with an automated audio output system. The authorization application automatically detects unread SMS messages containing security codes and synthesizes audio representations, eliminating the need for manual device handling and reducing authorization time
2Reliability
If the user must physically access the secondary device to retrieve the security code, then the security code delivery is reliable, but the ease of operation deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the authorization application automatically monitors for unread SMS messages containing security codes and proactively synthesizes and outputs audio representations without requiring user intervention. The system serves itself by automatically detecting, processing, and delivering the security code information, thereby improving ease of operation while maintaining reliable code delivery
Solution Approach 2:
The audio synthesis and output system acts as an intermediary that bridges the gap between the SMS message delivery and the user's perception of the security code. This intermediary layer automatically converts the text-based SMS into audio format and delivers it through the device's speaker, eliminating the need for physical device access while maintaining the reliability of the original SMS delivery mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for faster and more reliable user authorization by enabling code access without physical retrieval of the secondary device, significantly reducing the likelihood of authorization failures due to code expiration.
Implementation Method 1
synthesizes an audio representation of the security code (e.g., using a test-to-speech algorithm). The audio representation is then outputted using a speaker of the first device
Data Source
AI summary
Systems and methods are described for providing a security code to a second device. A first device receives a textual representation of a security code that is required for authorization of a second device with a remote application server. The first device checks if the textual representation of the security code is accessed during a predefined time period. If not, the first device also checks if the second device is within an output range of the first device. If so, the first device outputs an audio representation of the security code.
