Audio Signal Authentication for Streaming Media Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in automatically identifying and connecting to suitable streaming media content devices, as existing methods lack effective authentication mechanisms to distinguish between devices, potentially leading to unauthorized connections.
Innovation Solution
The method involves identifying candidate streaming media content devices using detected beacons, transmitting instructions for them to broadcast a signal containing an identity value, and processing an audio signal to authenticate the connection between a user device and the selected device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic device detection and connection is implemented, then ease of operation is improved, but security and authorization control deteriorate
Solution Approach 1:
The patent introduces an authentication intermediary mechanism that mediates between automatic device detection and connection establishment. The system detects candidate devices automatically but requires authentication verification through exchanged signals before establishing the connection, thus preventing unauthorized access while maintaining ease of operation.
Solution Approach 2:
The patent performs preliminary authentication actions before final connection establishment. The system exchanges authentication signals and verifies device identities in advance, ensuring authorization security is established before the actual media streaming connection is formed.
2Reliability
If device authentication mechanisms are added, then authorization security is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex manual authentication mechanisms with automated signal exchange and electronic verification processes. The authentication system uses automated signal processing and digital verification methods, substituting mechanical or manual authentication steps with electronic automation to reduce overall system complexity.
Solution Approach 2:
The authentication system operates autonomously through self-service mechanisms where devices automatically exchange authentication signals and verify identities without requiring complex external authentication infrastructure or manual intervention, thereby reducing system complexity.
3Measurement precision
If signal processing for authentication is implemented, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic signal exchange and authentication verification rather than continuous monitoring. The system performs authentication signal processing at specific intervals and only when needed, reducing continuous energy consumption while maintaining sufficient measurement precision for accurate device identification and authentication.

AI summary
Mechanisms for authenticating a connection between a user device and a streaming media content device comprising: identifying a collection of candidate streaming media content devices based on beacon(s) detected by a user device; receiving an indication that one of the content devices is to be selected for connection to the user device; transmitting instructions to the content devices to broadcast a signal, wherein the signal broadcast by each of the content devices contains a value that indicates an identity of the content device; receiving, from the user device, an audio signal that includes a detected signal; processing the audio signal to extract the value indicating the identity of a particular content device associated with the detected signal contained in the received audio signal; identifying the particular content device based on the determined value; and transmitting an indication that the user device and the particular content device are authenticated to communicate.
