Mobile App Voice Insertion for Confidential Call Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Confidential information shared during voice calls in public places is at risk of being overheard by third parties, and whispering or speaking clearly may not be practical due to background noise or accent issues.
Innovation Solution
A mobile application that securely provides confidential information by inserting a voice sample of the information into the audio stream of a voice call, ensuring it is audible only to the intended recipient, while preventing unauthorized access and eavesdropping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If confidential information is spoken out loud during a voice call, then the recipient can clearly hear and understand the information, but third parties in close proximity may overhear and misuse the information
Solution Approach 1:
The patent introduces an intermediary system (mobile application with audio processing capabilities) that mediates between the speaker and the audio environment. The application captures the spoken confidential information, processes it through security protocols, and transmits it through secure channels, thereby preventing direct acoustic propagation that would allow third-party overhearing while maintaining clear transmission to the intended recipient
2Object-affected harmful factors
If confidential information is whispered during a voice call, then third parties are less likely to overhear the information, but the recipient may not clearly hear the information due to background noise
Solution Approach 1:
The patent replaces the mechanical/acoustic system of whispering with a digital signal processing system. Instead of relying on reduced acoustic volume, the system uses software-based noise cancellation, audio enhancement, and secure transmission protocols to ensure clear delivery of confidential information without requiring the speaker to whisper, thus avoiding both overhearing risks and clarity loss
3Ease of operation
If a person speaks clearly during a voice call, then the recipient can easily understand the information, but the information may be overheard by third parties in public places
Solution Approach 1:
The mobile application serves as an intermediary that captures clear speech through the device microphone, processes the audio signal through security protocols, and transmits it via encrypted channels. This allows the speaker to maintain natural clear pronunciation while the intermediary system prevents third-party interception through secure digital transmission rather than acoustic propagation
Solution Approach 2:
The patent substitutes the acoustic transmission mechanism with a digital communication mechanism. Clear speech is captured and converted into digital signals that are transmitted through secure protocols, replacing the physical sound wave propagation that would allow overhearing while maintaining the ease of clear speech production

AI summary
Systems and methods disclosed herein securely provide confidential information associated with a user during an active voice call conducted using the user's mobile device. The confidential information may be provided by generating the information in spoken form and inserting the spoken information into an audio stream of the voice call. For example, a customer may be on a phone call with a customer agent. The customer agent may ask the customer for a credit card number in order to process a financial transaction. The customer may select the credit card number via an application executing on the customer's mobile phone. The application may cause the credit card number to be spoken out loud during the voice call. A voice sample of the spoken credit card number in inserted into the audio stream of the voice call and is therefore, audible to the customer and the customer agent without being overheard by a third party.
