Abstract
A device for authenticating a user is described that comprises a sensor configured to measure the movement of a user in response to the interaction of the user with a displayed image and controller circuitry configured to authenticate the user in response to a positive comparison between the movement of the user and a stored movement associated with the user.
Claims14
A device for authenticating a user, comprising:
- microphone circuitry configured to capture an ambient sound over a predetermined period, and
- controller circuitry configured to:
- measure the energy of the ambient sound over a predefined period;
- compare the time series of the measured energy with a received time series of the measure of the energy of the ambient sound from a second device known to be close to the user, wherein the measured energy includes no personal information from the ambient sound;
- and
- authenticate the user of the second device as the user of the device in the event of a positive comparison.
A method of authenticating a user of a device, the method comprising:
- storing a table that includes a device identifier for each device associated with the user and a location that indicates whether each device is close to the user;
- capturing, using microphone circuitry, an ambient sound over a predetermined period measuring the energy of the ambient sound over a predefined period;
- comparing the time series of the measured energy with a received time series of the measure of the energy of the ambient sound from a second device known to be close to the user;
- and
- authenticating the user of the second device as the user of the device in the event of a positive comparison.
A device for authenticating a user, comprising:
- a memory that stores a table that includes a device identifier for each device associated with the user and a location that indicates whether each device is close to the user;
- microphone circuitry configured to capture an ambient sound over a predetermined period, and
- controller circuitry configured to:
- measure the energy of the ambient sound over a predefined period;
- compare the time series of the measured energy with a received time series of the measure of the energy of the ambient sound from a second device known to be close to the user;
- and
- authenticate the user of the second device as the user of the device in the event of a positive comparison.
A non-transitory computer readable storage device having computer readable instructions that when executed by circuitry case the circuitry to:
- capture an ambient sound over a predetermined period
- measure the energy of the ambient sound over a predefined period;
- compare the time series of the measured energy with a received time series of the measure of the energy of the ambient sound from a second device known to be close to the user, wherein the measured energy includes no personal information from the ambient sound;
- and
- authenticating the user of the second device as the user of the device in the event of a positive comparison.
