Secure Voice Channel Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for secure data transmission on mobile devices are cumbersome, requiring additional hardware, password entries, and public key/private key systems, making it difficult to establish secure voice and data connections between users.
Innovation Solution
Establishing a secure voice communication session using existing voice call channels, allowing secure data transfer through the same or separate channels, with the option to automatically delete data after a set time period, simplifying the process and reducing user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional secure data transmission systems are used, then security is achieved, but device complexity and ease of operation deteriorate due to additional hardware, passwords, and key systems
Solution Approach 1:
The patent combines voice communication and data transmission into a single integrated secure channel. The voice call establishes a secure communication path that automatically enables encrypted data transfer without requiring separate security systems, hardware tokens, or key management infrastructure. This merging eliminates the complexity of multiple security layers while maintaining end-to-end encryption.
Solution Approach 2:
The voice communication channel serves multiple functions: it provides both voice transmission and a secure authenticated data transmission path. The same communication infrastructure that carries voice traffic also establishes cryptographic credentials that enable secure data sharing, eliminating the need for dedicated security hardware or separate authentication systems.
2Reliability
If conventional secure data transmission systems are used, then security is achieved, but ease of operation deteriorates due to password entry and key system setup
Solution Approach 1:
The system automatically performs authentication and establishes secure credentials through the voice call process itself. Users do not manually enter passwords or configure key pairs; the voice communication protocol automatically exchanges and verifies cryptographic credentials, and the secure data channel is automatically established based on the authenticated voice connection.
Solution Approach 2:
The secure authentication credentials are established in advance during the voice call setup phase. Before any data transmission occurs, the cryptographic handshake and credential verification are completed automatically, so that when data needs to be transmitted, the secure channel is already prepared and authenticated, eliminating the need for users to perform security setup steps at the moment of data sharing.
3Reliability
If secure data is transmitted during communication sessions, then data security is improved, but loss of time increases due to establishing secure connections in advance
Solution Approach 1:
The secure communication channel established during the voice call remains active and authenticated for the duration of the call, allowing data to be transmitted at any point during the conversation without interrupting the flow or requiring additional setup. The cryptographic credentials remain valid throughout the call, enabling seamless data sharing whenever needed during the communication session.
