Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security technologies for mobile devices lack effective solutions for quickly connecting users in dangerous situations to appropriate responders, such as emergency services, and for securely recording and storing incident data for evidence.
Innovation Solution
A method and device that enable two-way audiovisual teleconferencing between mobile computing devices, using peer-to-peer connections to identify and select suitable responders based on location, ratings, and situation type, while recording and transmitting video data with encryption for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security systems are used for mobile devices, then basic surveillance is possible, but rapid connection to appropriate responders and secure evidence collection is not achieved
Solution Approach 1:
The system pre-establishes peer-to-peer network connections with multiple potential responders before emergencies occur. When a user activates security features, the connection is already in place, enabling immediate video communication and evidence transmission without delay for responder selection or connection establishment.
Solution Approach 2:
The mobile device acts as an intermediary between the user and responders, capturing video evidence locally and transmitting it through the established peer-to-peer connection. This intermediary role enables simultaneous evidence collection, secure transmission, and real-time communication without requiring traditional centralized server mediation.
2Productivity
If peer-to-peer connections are established for rapid responder connection, then response speed improves, but system complexity increases
Solution Approach 1:
The system performs connection establishment and responder selection in advance, before the emergency occurs. Multiple peer-to-peer connections are pre-configured with potential responders, so when activation happens, the system simply activates an existing connection rather than establishing new ones under pressure.
Solution Approach 2:
The system dynamically adjusts connection parameters based on the emergency situation. When a peer-to-peer connection is available, it is activated immediately; otherwise, the system falls back to traditional server-mediated connections, changing the operational parameters based on real-time conditions.
3Loss of information
If video recording and transmission is implemented for evidence collection, then evidence availability improves, but data security risks increase
Solution Approach 1:
The mobile device serves as a secure intermediary that captures video evidence locally using the device's camera and processing capabilities, then transmits it through encrypted peer-to-peer connections. This approach avoids uploading raw footage to potentially insecure cloud storage while maintaining evidence integrity through local control and secure direct transmission.
Solution Approach 2:
The system replaces traditional centralized video storage and transmission infrastructure with a distributed peer-to-peer architecture. Instead of relying on server-based storage and transmission protocols, the system uses direct device-to-device connections with end-to-end encryption, substituting mechanical/centralized systems with decentralized cryptographic protocols.

AI summary
In one implementation, a computer-implemented method includes determining a location of a mobile computing device using one or more of a plurality of data sources; communicating, by the mobile computing device, with another computing device as part of a two-way video chat session over a first network connection, the communicating including transmitting the location of the mobile computing device; displaying, as part of the two-way video chat session, real-time video from the other computing device; recording video using one or more cameras that are accessible to the mobile computing device; and transmitting, over a second network connection, the video to a remote storage system for persistent storage.
