Patent Searching and Data


Title:
The audio data collection privacy in a mobile device is protected.
Document Type and Number:
Japanese Patent JP5937202
Kind Code:
B2
Abstract:
Techniques are disclosed for using the hardware and/or software of the mobile device to obscure speech in the audio data before a context determination is made by a context awareness application using the audio data. In particular, a subset of a continuous audio stream is captured such that speech (words, phrases and sentences) cannot be reliably reconstructed from the gathered audio. The subset is analyzed for audio characteristics, and a determination can be made regarding the ambient environment.
