Voice-Controlled Message Delivery via NFC Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-controlled sharing systems for information between paired devices lack efficient time-shifted delivery of messages and secure, context-aware output, particularly in shared networks, which can lead to irrelevant or private information being delivered at inappropriate times.
Innovation Solution
A method where a common computing device in a shared network receives message content from one device, detects the intended recipient, and outputs the message audibly in natural language, using NFC for authentication and secure access to personal information, allowing delayed delivery based on user commands and context awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If message content is transmitted immediately upon receiving in a shared network, then information delivery speed is improved, but privacy and context-appropriateness deteriorate as messages may be delivered at inappropriate times without user presence verification
Solution Approach 1:
The system performs preliminary actions by storing message content and delivery instructions in advance, then waits for the appropriate condition (user presence detection via NFC) before executing the actual message delivery. This resolves the contradiction by decoupling message receipt from message delivery, allowing speed improvement through immediate storage while ensuring reliability through condition-based delivery execution.
2Ease of operation
If voice-controlled sharing is implemented in shared networks, then ease of operation is improved, but security and accuracy worsen as personal information may be accessed without proper authentication
Solution Approach 1:
The system introduces NFC authentication as an intermediary step between voice command issuance and personal information access. The voice command initiates the process, but the NFC authentication intermediary verifies user identity and authorization before allowing the common computing device to access and output personal information from the personal computing device. This resolves the contradiction by maintaining voice command ease of operation while adding a security layer that prevents unauthorized access.
3Productivity
If personal information is accessed and output without authentication, then productivity is improved through rapid information delivery, but harmful factors increase due to privacy violations and inappropriate information disclosure
Solution Approach 1:
The system performs preliminary authentication via NFC chip detection and verification before accessing personal information. This preliminary action ensures that only authorized users can trigger information delivery, preventing privacy violations while maintaining efficient information delivery for authenticated users. The authentication step is performed in advance, allowing rapid information delivery subsequently without compromising security.

AI summary
A voice-commanded common computing device may be selectively paired other computing devices in a shared network. The common computing device may detect co-presence of paired devices on the shared network, and may determine when audio and/or video content may be cast to devices on the shared network based on the detected co-presence. Audio content may include messages composed by a first user of a first device in the shared network, to be audibly output to a second user of a second device in the shared network. Casting of personal information may include positive authentication and verification prior to audible output of the personal information.
