1. A method, in a data processing system, for utilizing a voiceprint to authorize a user to perform an operation restricted to authorized users, comprising: a first computing device transmitting an utterance request; the first computing device processing a first utterance in reply to the utterance request to create a voiceprint; a storage system storing the voiceprint in an audio attribute file; the storage system associating the voiceprint in the audio attribute file with a user of a virtual universe provided in the data processing system; the first computing device receiving a second utterance associated with the user; and performing identification of the user based on the second utterance by comparing the second utterance to the voiceprint; if the identification is successful, allowing the user to access services or authorizing the user to perform operations that are restricted to authorized users; detecting a movement of an avatar representing the user in a first virtual environment provided by the first computing device to a second virtual environment of a second computing device, different from the first computing device; and in response to detecting the movement of the avatar from the first virtual environment to the second virtual environment, transmitting the audio attribute file to the second computing device, wherein the audio attribute file is used by the second computing device to identify the user for accessing services or authorizing the user to perform operations that are restricted to authorized users on the second computing device.
