Skull Conduction Headset Biometric Access Control

The patent introduces a server as an intermediary that handles the complex biometric identification and content filtering tasks. The server receives skull conduction frequency data from headsets, identifies participants, determines their authorization levels, and filters confidential content accordingly. This mediator approach transfers the computational complexity from client devices to the server, improving information security while minimizing the impact on device complexity.

The patent replaces traditional mechanical or manual identification methods with skull conduction frequency biometric identification. This substitution uses acoustic/physiological properties (skull conduction frequency) instead of physical tokens or manual verification, enabling automatic participant identification and authorization verification, thereby improving information security without requiring complex hardware changes at the client end.

The patent implements preliminary action by pre-processing and indexing voice content as it is generated, rather than waiting for complete sentences or pauses. The system continuously analyzes speech-to-text conversions in real-time, identifying confidential keywords and contexts as they appear. This allows the filtering to keep pace with the conversation flow, minimizing delays while maintaining information security.

The system employs skipping by rapidly processing and filtering content in real-time without waiting for complete turns or pauses in conversation. When confidential content is detected through keyword matching and natural language processing, the system immediately mutes unauthorized participants, rather than waiting for the natural end of a speech segment. This rushing through the processing pipeline minimizes the perceived delay while ensuring security.
