Abstract
There is provided a system and method for secure voice identification in a medical device. More specifically, in one embodiment, there is provided a method comprising receiving an audio signal, identifying one or more frequency components of the received audio signal, determining a permission level associated with the one or more frequency components, determining a medical device command associated with the one or more frequency components, wherein the medical device command has a permission level, and executing the medical device command if the permission level of the medical device command is at or below the permission level associated with the one or more frequency components.
Claims24
A method comprising:
- receiving an audio signal in a medical device;
- identifying a voice of a user from the received audio signal;
- determining a first permission level based at least in part on a role associated with the user;
- determining a medical device command associated with the audio signal, wherein the medical device command has a second permission level;
- and
- executing the medical device command if the second permission level is at or below the first permission level.
A medical device comprising:
- an audio processing system configured to process a voice command into voice command data;
- an audio recognition system configured to identify the voice command as spoken by one of a plurality of voices based at least in part on the voice command data, wherein the audio recognition system is configured to determine a command for the medical device from the voice command data, wherein the command has an associated permission level;
- a permission database configured to store a permission level associated with one or more of the plurality of voices, wherein the permission level is based at least in part on a medical role associated with the one or more of the plurality of voices;
- and
- a control system configured to determine the permission level associated with the medical role based on the permission database, wherein the control system is configured to execute the determined command if the permission level of the determined command is at or below the permission level associated with the medical role.
A method of operating a medical device comprising;
- receiving an unlock signal in the medical device, wherein the unlock signal is configured to allow operational parameters of the medical device to be altered;
- determining a permission level associated with the unlock signal;
- receiving a voice command in the medical device;
- determining permission level associated with the received voice command;
- and
- executing the received voice command in the medical device if its permission level is at or below the permission level associated with the unlock signal.
A medical device configured to:
- receive an unlock signal configured to allow operational parameters of the medical device to be altered;
- determine a permission level associated with the unlock signal;
- receive a voice command;
- determine permission level associated with the received voice command;
- and
- execute the received voice command if its permission level is at or below the permission level associated with the unlock signal.
