Abstract: Examples disclosed herein provide the ability to identify the location of an individual within a room by using a combination of microphone arrays and voice pattern matching. In one example, a computing device may extract a voice detected by microphones of a microphone array located in a room, perform voice pattern matching to identify an individual associated with the extracted voice, and determine a location of the individual in the room based on an intensity of the voice detected individually by the microphones of the microphone array.

Abstract: An example non-transitory computer-readable medium includes instructions that, when executed by a processor, cause the processor to receive a request for data. The instructions also cause the processor to determine a region containing the data based on the metadata. The instructions cause the processor to traverse a tree in the metadata to determine key generation information relating a decryption key for the region to a root key.
