Mobile Device Panic Recording with Audio Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular telephone systems lack a reliable method to record unwanted or harassing conversations, which can be crucial for evidence in cases of potential violence or missing persons cases, as users often cannot initiate recording in time.
Innovation Solution
A system and method for recording conversations on portable communications devices, allowing users to activate recording via a panic button or code, with an optional buffer feature to capture previous conversation segments, storing the recordings on device memory or a network database for later use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually initiate recording by pressing a panic button or entering a code, then the recording can be activated on demand, but the user may not have time to start recording when a threat occurs suddenly
Solution Approach 1:
The system performs preliminary action by continuously buffering recent conversation segments in memory before the user activates recording. When the user presses the panic button, the buffered content is immediately appended to the recording, eliminating the delay between threat detection and recording activation. This ensures that even sudden threats are captured without requiring the user to wait for recording initiation.
2Reliability
If the recording buffer stores recent conversation segments, then sudden threats can be captured, but the device complexity increases
Solution Approach 1:
The recording system is segmented into distinct functional components: a continuous buffer that stores recent conversation segments, a trigger mechanism that detects panic button activation, and an appender that combines buffered content with new recording. This segmentation allows each component to perform its specific function efficiently, managing complexity through modular design while ensuring reliable capture of sudden threats.
3Loss of information
If conversations are recorded and stored, then evidence can be provided for law enforcement, but the storage requirements and data management complexity increase
Solution Approach 1:
The system extracts and stores only the relevant portions of conversations - specifically, the segments surrounding threat events triggered by panic button activation. Rather than storing entire conversations, the buffer captures only recent segments (e.g., last 1-2 minutes) that are likely to contain evidence, reducing storage requirements and data management complexity while preserving critical evidence for law enforcement.

AI summary
Devices, systems and methods are disclosed which relate to recording a conversation on a portable communications device. This allows the user to press a panic button or a series of buttons on their portable communications device to begin recording the conversation. This conversation may be stored on a memory of the portable communications device or in a network in communication with the portable communications device. With the conversation recorded, there is a record of what was said during the call. This record may later be used if necessary.
