Technologies are generally described for systems, devices and methods effective to identify an individual. In some examples, a microphone may receive sound data such as sound that may be present in a mall. A processor, that may be in communication with the microphone, may determine a name from the sound data. Stated differently, the processor may determine that the name is part of or included in the sound data. The processor may generate a query based on the name and may send the query to a social network database. The processor may receive a response to the query from the social network database and may identify the individual based on the response.
